Monday June 2, 2014
Inaugural session
Ismael Herrera (Geophysics Institute UNAM) . My life in science, as I understand it today

1 .- Monday June 2, 2014

Computational seismology
Convener – Jacobo Bielak (Carnegie Mellon University)
Convener – Héctor Benitez (IIMAS, UNAM)
Invited speaker: Víctor Cruz Atienza
Invited speaker:  Leonardo Ramírez-Guzmán  (IINGEN, UNAM)

In this session we will cover different aspects of computational simulation in seismology, including both forward and inverse problems in earthquake seismology. Priority will be given to contributions that show innovative mathematical, numerical, or computational methods, especially those that address verification or validation. Applications may include, for example, rupture dynamics, ground motion in complex geological systems with small- scale heterogeneity, and full 3D tomography for crustal structure.

Four paradigms in predicting extremes: Legacy of Vladimir I. Keilis-Borok
Conveners - Alik Ismail-Zadeh,Karlsruhe Institute of Technology, Germany
Ilya Zaliapin, University of Nevada Reno, USA
Yehuda Ben-Zion, University of Southern California, USA
Invited speaker: George Molchan, Russian Ac. Sci., Russia
Invited speaker: Andrei Gabrielov, Purdue University, USA 
Invited speaker: Maxim Arnold, Russian Ac. Sci., Russia       
Invited speaker: Antonella Peresan, University of Trieste, Italy
Invited speaker: Jorge Ramirez, National University of Colombia, Colombia
Invited speaker: Robert Shcherbakov, Western University, Canada

Natural and socio-economic disasters pose an intolerable threat to society. The most damaging and least understood in this realm are extreme events, also called critical transitions, disasters or catastrophes. The symposium will review the state of the art and outline directions for future research in the science of forecasting extreme events.  The symposium will bring together the world-leading experts in the field as well as researchers from the new generation to discuss the mathematical problems of risk assessments, forecasting, impact evaluation, and designing the corresponding mitigation strategies. The goal is to showcase the recent progress, share the knowledge among different disciplines, and develop tools that can be used by disaster management authorities. The symposium is dedicated to the memory of Professor Vladimir Keilis-Borok who passed away on October 19, 2013. During the 20th century, Vladimir Keilis-Borok has pioneered applications of mathematical, probabilistic, and computer methods in seismology.  Vladimir Keilis-Borok has founded the Working Group on Geophysical Theory and Computers (WGGTC), which later had transformed into the IUGG Commission on Mathematical Geophysics (CMG). Professor Keilis-Borok was Vice President of the International Association of Seismology and Physics of the Earth Interior (IASPEI). During 1987-1991 he was the President of the IUGG.

3.- Tuesday June 3, 2014

Nonlinear phenomena in the climate system
Convener- Henk Dijkstra (Institute for Marine and Atmospheric research Utrecht - IMAU)
Convener- Chris Jones (University of North Carolina, USA)
Invited speaker: Mickael D. Chekroun (University of California, Los Angeles USA)
Invited speaker: Michael Högele (Universität Potsdam)

Nonlinear processes affect the behavior of most phenomena in the geosciences. The climate system, in particular, is an example of a nonlinear system in which
interactions  between many different processes take place on a multitude of temporal and spatial scales.  These nonlinear interactions lead to strong internal variability, due to the existence of substantial instabilities and related feedbacks. The resulting, highly complex intrinsic variability interacts in turn with  the time-dependent  variations in the forcing and gives  the rich and intriguing behavior that is documented in the instrumental data and proxy records.
The theory of  nonlinear, stochastic dynamical systems provides a systematic methodology,  as well as a  synthesizing framework to understand the behavior of complex  systems. Over  the last  decades, the application of this theory to climate variability has provided many  new  insights into mechanisms of internal variability. In addition,  many of the concepts  are used now in nonlinear methods of data analysis, stochastic  parameterizations, data assimilation techniques and predictability studies. In this  session, we welcome work related to the broad theme of nonlinear phenomena  in the  climate system or any of its components (ice, ocean, air, land, life), preferably studied within the nonlinear stochastic dynamical systems framework.

4.- Tuesday June 3, 2014

Mathematical and numerical modeling of enhanced oil recovery
Convener – Luis Miguel de la Cruz (Geophysics Institute UNAM)
Convener – John Chen (University of Calgary)
Invited speaker: Dr. Renee Perez Rodriguez. Information about the speaker can be found at:

Enhanced Oil Recovery (EOR) is a term used to identify sophisticated techniques to increase the recovery of hydrocarbons from oil fields.
Complex chemical and thermal effects are the main processes used in several different EOR methods. Numerical simulation of these processes is required to design new technologies for exploration and production of oil and gas.
The complexity of the mathematical models of EOR requires devising of sophisticated and efficient numerical strategies to obtain accurate solutions of these models. EOR is a large-scale problem with growing computational demands; therefore, parallel computing is a practical route to effectively solve these kinds of problems.
The objective of this session is to bring together researchers from several fields of knowledge, with interest in oil recovery applications. Works covering different aspects of computational modelling of hydrocarbons recovery are welcome, such as: mathematical formulations of the involved phenomena; devising of new numerical strategies; computational implementation, serial and parallel, of algorithms; analysis and validation of numerical results.

5.- Wednesday June 4, 2014

Fluids, friction and rheology, in rocks and porous media
Convener - Renaud Toussaint (Univ. Strasbourg, France)
Convener – Graciela Herrera-Zamarrón (Geophysics Institute UNAM)
Invited speaker: Stefan Nielsen
Invited speaker: David Sparks

Understanding friction and the localization of deformation is essential in Earth science systems. Notably, it is key to understand the initiation and the mature functioning of faults, in more or less permeable and fractured rocks (as e.g. in reservoirs). Different types of friction and rheological changes are also at the heart of numerous surface phenomena: to name a few, avalanches and gravitational instabilities in soils and granular media, or liquefaction events, some types of eruptions. They also impact problems related to industry and geotechnics, as during drilling activities and reservoir exploitation.
In many of these systems, fluids and their transport play a key role: both from a physical point of view, to exchange momentum while fluid seeps through pores and fractures, or from a chemical point of view, to dissolve and precipitate material, change the physical properties of the medium, transport material, clog porosity. It also plays a key role in the transport of energy and in the determination of the temperature field. In many physically coupled systems, the presence of fluids and fluid interfaces, their composition and temperature can affect frictional properties and trigger phase changes in the material, e.g. during thermal pressurization episodes.
This session welcomes contributions on this wide range of phenomena related to rheology, friction and fluids in rocks and soils: We wish to gather several points of views, and welcome contributions on diverse angles on this topic, or a combination of such - between physical and analytical theory, numerical modeling, experimental approach, and field characterization and observation.

6.- Wednesday June 4, 2014

Ambient seismic noise, diffuse fields and interferometry
Convener – Francisco Sánchez Sesma (Engineering Institute UNAM)
Convener – Michel Campillo (ISTerre, University J Fourier, Grenoble)
Invited speaker: Nishida Kiwamu, Earthquake Research Institute, University of Tokyo
Invited speaker: Joost van der Neut Delft University of Technology

The retrieval of Green´s functions from the average of cross-correlations of ambient fluctuation within a diffuse field has attracted considerable attention from different areas of geophysics. In fact, ambient seismic noise and coda waves can be used to infer information of mechanical properties of Earth. For a variety of linear systems the formal derivation can be obtained from representations in normal modes and plane waves. Time-reversal and representation theorems have been used as well. Closely related is interferometry in which cross-correlations are useful to produce virtual sources and to improve the illumination for imaging purposes. This session is concerned with theory and applications of diffuse fields and interferometry in geophysics. The emphasis will be laid to mathematical, numerical or computational innovative contributions.

In this session we accept contributions analyzing all the exchanges and feedbacks at the surface interfaces of the planet. These include physical and biogeochemical processes happening at the most diverse time and space scales, involving the interaction of the atmosphere with the continental land surface and the oceans. Priority will be given to contributions showing innovative mathematical, numerical or computational methods. Applications may include for example the atmospheric interactions of surface hydrology and vegetation, the urban atmosphere dynamics, land-use change effects and extreme weather events.
