Geoscience applications of satellite earth observations
Michael G. Sideris
Department of Geomatics Engineering, University of Calgary

This talk will introduce the International Union of Geodesy and Geophysics (IUGG) and its eight Associations and their Earth observation activities and Services. Emphasis will be placed on satellite Earth observations, their contributions to geosciences and their applications, including their societal impacts. Current research challenges will be highlighted, together with the need for continuous, long-term, sustainable satellite observations, and hence also satellite missions such as, e.g., the altimetry, gravity and magnetics ones, which would help us meet these challenges now and in the future by addressing important UN priorities such as the sustainable development goals, the Sendai framework and the Paris agreement.

How to generate a large earthquake
John Mackrain Fletcher
Departamento de Geología, CICESE

Regardless of global tectonic regime, most large earthquakes activate slip on more than one fault. Likewise, earthquake magnitude increases with the number of faults activated. Despite the importance of multifault ruptures for forecasting seismic hazard, their genesis remains poorly understood and classical applications of static yield criteria are inadequate to describe the mechanical conditions required to prepare multiple faults with diverse orientations to fail simultaneously in a single earthquake. This is because the critical stress level for fault failure depends greatly on fault orientation and is lowest for optimally oriented faults positioned approximately 30° to the greatest principal compressive stress. The most popular explanations of fault network stability call upon variations in pore pressure and/ or friction such that misoriented faults are systematically weaker than other more optimal faults. However, there is no reason why the internal strength of a fault should vary with its orientation and thus we reject all such hypotheses. In this talk I will present a new explanation of multifault ruptures called the keystone fault hypothesis, which provides new insight into mechanics of large earthquakes and the role of misoriented faults in controlling the limits of lithospheric stress (Fletcher et al., 2016, Nature Geoscience).

Global advancements in forensic geology
Laurance Donnelly
Initiative on Forensic Geology, IUGS

Although the origins and applications of geology to police and law enforcement criminal investigations has been documented since the middle part of the 19th Century, during the past few decades there have been significant advances in forensic geology (known also as ‘forensic geoscience’ or ‘geoforensics’). The objective of this presentation is to provide an overview of these recent developments.

Crime scene examination is the application of geological knowledge at crime scenes. A forensic geologist may be required to assist law enforcement at a crime scene to; collect geological samples and provide interpretations of the soil, sediment, rocks, and man-made materials.

Geological trace evidence involves the collection, analysis, interpretation, presentation and explanation of geological evidence. This evidence could become transferred onto the body, person or the clothing of a victim or offender, or onto vehicles, or other objects from and to a crime scene to help with crime reconstruction. This may also be admissible as evidence in a court to support a prosecution or defence.

Ground searches for burials are designed and implemented to locate homicide graves or items buried as part of a criminal or terrorist act. As such, searches may be protective or detective and take place in urban, rural or remote locations, on land or in water. The geoforensic search strategy (GSS), which developed over a period of 25 years provides a framework for a high assurance strategy. This is based on law enforcement search methods and an understanding of the ground and target conditions to produce a preliminary conceptual geological model. Upon which, the diggability of the ground, detectability of the target can be evaluated. This then enables the most suitable array of search assets (e.g. remote sensing, drone, geophysics, geochemistry, victim detector dogs and auguring) to be chosen. The GSS provides a proportionate, pragmatic and cost-effective method for a buried target to be detected and located, or prove (so far as is reasonable practicable) that is not present. The GSS is a blended geological and law enforcement strategies the requires effective collaboration and communication with between the forensic geologist law enforcement officer.

Crime in the minerals and mining industry occurs world-wide, in particular throughout Mexico and South America. This involves criminal and illegal mining, conflict minerals, theft of refinery and smelter products such as mineral concentrates, fraudulent activities including sample switching or adulteration to falsify assays (also known as ‘saltation’), cross border minerals smuggling and minerals fakery. These are usually controlled by illegal armed gangs, cartels and organised syndicates. Forensic geologists in collaboration with law enforcement are developing methods to deter or detect these crimes. This includes the adaptation of international guidance, elemental and mineralogical profiling, now used by some companies and governments to track and verify precious metal trading such as, gold and platinum group metals. Other techniques may include; field portable x-ray fluorescence, x-ray diffraction, conventional microscopy, automated scanning electron microscopy, the use of microtaggants and an auditable chain-of-custody.

This presentation will also provide an overview on the ongoing professionalisation of forensic geology, the establishment and progress of formal international working groups, such as the International Union of Geological Sciences (IUGS), Initiative on Forensic Geology (IFG). The need for regulation, accreditation, training and continuation of professional development within the forensic geology professional is also highlighted. Operational case examples are provided throughout with emphasis on Mexico and South America.

Rising green tides and brown tides: an oceanographic regime shift?
Chuanmin Hu
University of South Florida, USF

Blooms of Ulva and Sargassum macroalgae, often called green and brown tides, respectively, have been reported in many places around the world. These macroalgae provide important ecological functions in the ocean, but can cause many problems when large quantities are washed ashore. Using satellite data, field and laboratory measurements, and novel macroalgae-specific algorithms, we show bloom patterns of Ulva prolifera and Sargassum between 2000 and 2019 in the western Pacific (Yellow Sea and East China Sea) and tropical Atlantic. While their seasonality indicates algae growth cycles, large quantities detectable in satellite imagery only occurred in recent years. In particular, a continuous Sargassum belt extending from west Africa to the Gulf of Mexico is found to be recurrent every summer since 2011 (except 2013). Analysis of environmental conditions suggests that these recent large-scale blooms may be a result of both human activities and climate variability. We further hypothesize that these recurrent blooms may become a new norm in future years, thus representing potentially a regime shift. Given the significant impacts of these blooms on the coastal environment sand coastal communities, how to adapt to such a regime shift and what are its ecological/biogeochemical consequences all remain to be studied.

Space weather: who cares?
Clezio Marcos De Nardin
Instituto Nacional de Pesquisas Espaciais, INPE

Space Weather effects on the Earth and near-Earth assets has become of a large interest in the last decade, which motivate also studies on the economic impacts and risk assessment. As a result, several economic sectors that depend on the space weather condition are driving a growing demand for global indices to represent the impact of the solar-terrestrial interaction (external effects of the space weather) as well as the “extreme” variation of the near-Earth environment (internal effects of the space weather). This speech intends to compile the experience attained with developing the Space Weather Regional Warning Center in Latin America (especially at the Brazilian Studies and Monitoring of Space Weather -Embrace Program, from the Portuguese acronym Estudo e Monitoramento Brasileiro de Clima Espacial). Also, a revision of the principles associate with space weather phenomena, effects and the economic impacts to the current society are briefly review, as well as the efforts of transiting from research to operations in space weather in Latin America.

Title:
Modeling of atmospheric processes: theory and applications

Description:
The study of the dynamics of the atmosphere requires a balanced relationship between theory and experimentation. This area of ​​research has a well-documented set of conservation laws, which allows a rigorous theoretical treatment. However, the theoretical results refer mainly to idealized situations and, therefore, in real cases these results are only valid with some degree of approximation. However, the exact results obtained analytically under several simplifying assumptions are important not only as basic elements in the creation of a theory, but also to test computational algorithms and computer programs in numerical simulation. Therefore, it is necessary to supplement the theory with computational experiments.

The dynamics of the atmosphere is an exciting subject, with important practical applications ranging from weather forecasting and climate change to the dispersion of air pollutants and control of pollution sources.

We invite you to participate in this special session of the Annual Meeting of the Mexican Geophysical Union (RAUGM-2019), dedicated to the problems of mathematical and numerical modeling of atmospheric processes.

Basic topics:

1. Dynamics of the atmosphere (theory and experiments)
2. Atmospheric models of different levels of complexity
3. Exact solutions of the models
4. The asymptotic behavior of solutions of a model (attractive sets)
5. The stability of atmospheric flows
6. Chaos in the dynamics of the atmosphere
7. Weather Forecast (models and methods)
8. Climate Models (numerical experiments)
9. Pollutant dispersion models
10. Methods of estimating the pollutants
11. Methods to control emissions from sources of pollution
12. Methods of identification of unknown sources
13. Numerical methods and algorithms (approximation, stability, convergence)
14. Analysis of observation data
15. Comparison of the results of numerical models with observations
16. Methods of data assimilation (initialization of numerical models)
17. Methods of identifying the internal parameters of a model

Earth Science communication, outreach and education

Description:
We welcome communicators, research teams, institutions, students and professors that are involved in geoscience education, communication and/or outreach.

In the academy, a significant portion of time and resources are invested in communicating research topics. However, the spaces within disciplines to disseminate, dialogue and see from other perspectives the practice and outcomes of communication activities are not always easy to find. In this special session, we intend to provide a space for sharing and critically reflect about Earth Science communication, outreach and/or education experiences and projects, with the aim of spreading the best practices in the field and creating links that promote collaborations among participants. As a result, we expect that those dialogues will help strengthen geoscience communication in Mexico.

Title:
Regional climate modelling and CORDEX

Description:
Regional climate models are a powerful tool to improve knowledge of the physical, chemical and dynamic processes of the ocean-atmosphere-continent system that regulate the weather and the present climate and its possible changes. Computational growth has favored the development of a large number of global and regional climate models. Multi-institutional intercomparison projects of regional models such as CORDEX (Coordinated Regional Climate Downscaling Experiment) have generated outputs of regional climate models at 50 km and are generating simulations at even finer scales (25 km) forced with global models in a historical period and under different emission scenarios. This information is available to the scientific community and is relevant to process studies, to assess the possible impacts of climate change in different regions and for decision making and adaptation to climate change.

Papers in English and Spanish will be received in topics such as:
1) Implementation and validation of regional climate models in various regions of the world, with particular emphasis on CORDEX domains.
2) Studies of different present physical regional processes and their possible changes in different climate change scenarios, using regional climate models (dynamic or statistical downscaling).
3) VIA studies (vulnerability, impacts and adaptation) to climate change.

Title:
Physical Limnology

Description:
The research of physical limnology has been scarce compared with biochemical and ecology studies in several Mexican lakes.

The main purpose is to bring together diverse studies, from research projects as preliminary and published, focused on studies (water quality and biota) related to physical processes (wind driven currents, thermal structure, internal waves, mixing processes, transport, etc.).in lakes.

Also, it is to outline that tropical limnology is poorly understand compared with temperate limnology paradigms that are not observed in tropical lakes (such as the concept of thermocline).

In this session we are happy to cordially invite all scientist and students to participate in the conference and share the latest interdisciplinary issues about observational data, experimental, theory and numerical modeling, in different world lakes.

Title:
Deepwater oil spills: Looking to the future

Description:
The increasing demand for oil and gas is moving exploration and extraction into deeper ocean waters resulting in historic oil spill events. Two of the largest oil spills occurred in the Gulf of Mexico, Ixtoc 1 (1979-1980) and the Deepwater Horizon (DWH) in 2010. These events highlighted the necessity for sound scientific baseline data to assess the impact on the marine ecosystem, measure ecosystem resiliency and contribute to restoration strategies. The DWH event generated a considerable body of scientific data which will serve as basis for better preparation for the next mega-blowout, potentially in even deeper waters. The goal of this session is to present the state-of-the-art research in deepwater oil behavior and spill response. Contributions about the impact of mega oil spills on marine ecosystem, baseline data collection, ecosystem resiliency and integrated-comprehensive studies that could contribute to better preparation for a future spill are invited.

Title:
Disaster prevention for megathrust earthquakes and tsunamis in Mexico

Description:
The Pacific coast of Mexico faces a high risk of disasters for natural phenomena owing to the frequent occurrence of megathrust earthquakes and tsunamis. We require urgent attention to mitigate such a risk including Mexico City, where large subduction earthquakes may produce significant devastation. To this purpose we urgently need developing earthquake/tsunami hazard maps and tsunami evacuation guidelines to mitigate the damage caused by future megathrust earthquakes. A relevant educational program for disaster prevention in the coastal communities is also needed. Disaster prevention is only possible if we develop also a deep understanding of the physics governing the threatening phenomena. Thus, in this multidisciplinary session we welcome contributions from different disciplines leading to the mitigation of earthquake and tsunami disasters, such as investigations of the mechanisms behind earthquake and tsunami in subduction zones worldwide, leading instrumentation and methodologies for detecting and analyzing precursory processes, computational modeling of plausible scenario earthquakes and tsunamis for hazard assessment, risk estimation and educational methodologies for reducing the population vulnerability.

2017 Mw 8.2 Tehuantepec Earthquake

Description:
The 2017 Mw 8.2 Tehuantepec earthquake was one of the largest deep normal earthquakes ever recorded. Nonetheless it caused a tsunami and the largest number of aftershocks ever recorded in a Mexican earthquake. Plus there was the Mw 7.1 Puebla earthquake 11 days later (UTC), which it is still unclear if there was some interaction between the two. Shortly after the Tehuantepec earthquake, the University of Texas at El Paso together with the Universidad Autónoma de la Ciudad de Juarez and the Universidad Nacional Autónoma de México installed temporary broadband and short period networks to record aftershocks and develop local crustal models. This session will explore that data set. We also invite submissions studying this unusual earthquake beyond this unique data set. This includes studies of the resulting tsunami and any interactions with slow slip events in addition to the event itself.

Title:
Monitoring mass movements and transport processes in volcanic environment

Description:
Documentation and monitoring of mass wasting phenomena along active volcanos requires scientists to adopt a variety of methods. The difficulties in directly detect the initiation and the propagation of mass movement and transport processes, have progressively prompted research into surrogate monitoring technologies, such as photogrammetry and seismic techniques. Nowadays, the combination of distributed sensor networks and remote sensing techniques represent a unique opportunity to gather direct observations in such harsh environments. Consequently, a growing number of scientists with diverse backgrounds are dealing with the monitoring of processes ranging from lahars to pyroclastic flows. However, there is a need of standardization and validation of methods, techniques, and procedures to collect reliable monitoring data in a cost-effectiveness way. Participants are encouraged to present their results based on different methodologies, instruments and sensors, including remote sensing, flow modelling, monitoring and early warning system.

Title:
25 years of eruption at Popocatépetl Volcano: one of the Earth’s most dangerous volcanoes

Description:
Popocatépetl volcano (5,452 m a.s.l. central Mexico), woke up on December 21, 1994, after several years of increasing seismic and fumarolic unrest, and has been in a continuous eruptive period since then. The volcanic activity has been characterized by cycles of lava dome building and destruction, and has been slowly filling its 850 × 600 m wide summit crater. The intensity of the eruption has increased and waned over time, reaching its peak in 2000–2001, when a large lava domes grew rapidly, before being destroyed by a powerful sub Plinian phase that sent an ash column up to 17 km a.s.l. and produced 5 km long pyroclastic flows. Several other phases of strong activity have occurred since then, such as in March-June 2012, April-July 2013, or January-May 2015, September-November 2017, and February-April 2019. Arguably the most distinctive aspect of the whole eruptive period has been the extremely high emissions of volcanic gases, and the extreme disproportion between the emitted gas and the erupted lava. Popocatépetl is one of the strongest permanent emitters of volcanic gases, and the amount of gas produced over the whole eruptive period would have been enough to fuel a VEI6 eruptions had it been emitted in a few days instead of being emitted passively and permanently over 25 years.

However, Popocatépetl is capable of producing much stronger eruptions than the current one or those who have occurred since the Spanish colonization. Large effusive eruptions, five powerful Plinian eruptions and one massive sector collapse have occurred at the volcano during the last 25,000 years. This violent past, together with the extraordinary large population living around, makes of Popocatépetl volcano one of the highest-risk in the world. The hazard map, produced initially at the beginning of the eruption, was recently updated and improved, thanks to new geological surveys, and numerical modelling.

For this symposium, we are inviting any contribution related to Popocatépetl volcano, from geological study, inter-correlation of monitoring parameters, and modelling of volcanic processes, to civil protection and social response, in order to foster interaction between the numerous scientists, civil protection authorities, and communities that have been involved in the study or crisis management of this unique 25 years long eruption.

Title:
Risk analysis of the oil system

Description:
The work of the engineer must also be administrative and economic, and should not be oblivious to the estimation and risk management. The concept of risk is based on probability, because when working with the subsoil we are dealing with the unknown. That is Why the risk is higher than in other industries, but it is also more profitable, as long as it is handled well.

Oil Exploration in any place, region or country is a difficult task involving large capital and especially high risk. There Are different types of risks in the oil industry, however, the most relevant is the so-called Geological Risk or Exploratory Risk that directly involves the presence or not of hydrocarbons in an exploratory opportunity. In Order to produce an accumulation of hydrocarbons, a chain of processes must be fulfilled, ranging from the presence of a generating rock to the existence of “traps”, if a single link fails, the exploratory well to be perforated will not have successful results.

The objective of the course is to make known the elements of risks that are evaluated in the exploratory projects and to mention the different methodologies of analysis.

Title:
Acquisition of bathymetric data using a multibeam system, survey technics under different scenarios

Description:
During a bathymetric survey, the project faces different scenarios and complications during the acquisition process, this represent a challenge for the hydrographer, who is working to get the most sounding data and under the better levels of uncertainty. The objective of this course is to cover the themes of hydro-acoustics and their application to the multibeam systems, with the aim of get a better understanding of the process involved in the multibeam data acquisition. This will provide a set of tools for the hydrographers, so they can take all the needed decision to change the campaign plans and/or the run time parameters to ensure the quality of the data under any conditions. This change of conditions can be a consequence of the morphological changes of the sea bottom, environmental changes, type of installation, type of sea bottom, among others.

The specification and characteristics of a hydrographic survey can change according the needs and the type of data, such as: mapping of habitat, nautical charts, underwater archeology, bathymetry, bottom classification with backscatter, characterization of objects in water column, among others, consequently the survey plan and the operational parameter should be adjusted in concordance with the properties of the system. For this reason, during the course we will cover the requirement and demands of the main types of survey, estimating the proper configuration for each scenario.
