Learning From Earthquakes
EERI is organizing reconnaissance efforts to study impacts of the M8.1 and M7.1 Mexico earthquakes. Initial reconnaissance teams will be in the field from Sunday, October 1 – Sunday, October 8, 2017.
Gilberto Mosqueda, UC San Diego (M. EERI, 2001), and Lucy Arendt, St. Norbert College (M. EERI, 2008), will serve as EERI’s Reconnaissance Leaders. Together, Mosqueda and Arendt, who represent structural engineering and social science respectively, will conduct an initial reconnaissance trip to identify the major issues coming from these earthquakes, identify gaps in current reconnaissance efforts, and suggest recommendations for further EERI reconnaissance.
EERI is sending an Earthquake Early Warning Team of two seismologists and two social scientists to focus on the implementation of the earthquake early warning system. The team members are: Scott Miles, University of Washington (M. EERI, 2009); Richard Allen, University of California, Berkeley; Elizabeth Cochran, U.S. Geological Survey; and Diego Otegui, University of Delaware. The team aims to understand how well the system worked, who it reached, how people responded to the warning, and what lessons can be learned to inform how similar warning systems are implemented in other countries.
EERI is participating in a collaborative multi-organization effort to conduct quick damage assessments of all buildings in a specific radius or several block area that catalogues structural building types, damage severity, and other details. This effort is being led by Debbie Weiser, OneConcern (M. EERI, 2017), and Jeffrey Hunt, Exponent (M. EERI, 2010).
EERI has launched a new Virtual Earthquake Clearinghouse website for the M7.1 earthquake. This new website features a new resource library that can be filtered by category and a new photo gallery with enhanced search and data download features. The interactive data map is also available to view on the site. The resource library contains content from the Virtual Earthquake Reconnaissance Team (VERT) which includes information gleaned from the media on topics such as housing, ground motion, and social impacts.
With the large number of reconnaissance efforts being organized, EERI is conducting regular coordination calls amongst the teams to share plans and information. A special thanks to Eduardo Miranda (M. EERI, 1987), whose rapid reports from Mexico City helped inform other reconnaissance efforts. EERI is also thankful to the many colleagues in Mexico, including Sergio Alcocer (M. EERI, 1987), Gustavo Ayala (M. EERI, 1977), David de Leon (M. EERI, 2012), Arturo Tena-Colunga (M. EERI, 1989), and Eduardo Reinoso (M. EERI, 2001), who have shared information about the impacts of both earthquakes. Photo Credit (top): Eduardo MirandaBack to top >

Lohrasb Keykhosropour (M. EERI, 2016) and Kristin Ulmer (M. EERI, 2014) have been selected as the 2017-2018 EERI/FEMA NEHRP Graduate Fellows in Earthquake Hazard Reduction.
EERI awards graduate fellowships each year with support from FEMA and the National Earthquake Hazards Reduction Program. The award is given to foster the participation of capable individuals in furthering the goals and practice of earthquake hazard mitigation. The fellowships provide a stipend of $12,000 that can be used for tuition, fees, research expenses, and attendance at the 11NCEE and 2018 EERI Annual Meeting, June 25-29, 2018, in Los Angeles, California.
Lohrasb Keykhosropour from UC Irvine (Geotechnical Engineering) and Kristin Ulmer from Virginia Tech (Geotechnical Engineering) were selected from a group of highly qualified applicants in a variety of disciplines related to earthquake science and engineering at universities across the nation. EERI’s Student Activities Committee, consisting of nine faculty members led by University of Nebraska-Lincoln Associate Professor Terri R. Norton (M. EERI, 2004), reviewed the application packages and made the final selections. The committee awarded honorable mention to candidate AngelPerez Irizarry (M. EERI, 2011) from the University of Wisconsin Madison (Structural Engineering).
Lohrasb Keykhosropour is a Ph.D. student at UC Irvine whose doctoral research is focused on developing a data-driven computational framework to determine the magnitude and distribution of seismic soil pressures for deep flexible underground structures. Keykhosropour was born and raised in Iran. He graduated from Isfahan University of Technology in 2007 with a BS in civil engineering, and from Amirkabir University of Technology in 2011 with an MS in geotechnical engineering. Having spent three years working at a geotechnical firm in Iran, he realized his passion for research and desire to pursue an academic career, and immigrated to the U.S. to work towards a Ph.D. at UC Irvine. His goal is to become a professor, teach future engineers, and continue doing research work that can be directly translated into practice.
Kristin Ulmer is currently working toward her Ph.D. in civil engineering at Virginia Tech with Professors Russell Green (M. EERI, 1993) and Adrian Rodriguez-Marek (M. EERI, 1999) as her advisors. Her doctoral research is focused on developing an energy-based liquefaction evaluation procedure through laboratory testing and analysis of liquefaction case histories. One of Ulmer’s main career goals is to become an exceptional educator and mentor to the next generation of engineers. As an undergraduate at Brigham Young University she worked as a TA and math tutor, and currently serves as a peer mentor to undergraduate women in engineering disciplines.
The Institute looks forward to highlighting Lohrasb Keykhosropour's and Kristin Ulmer's research at the 11NCEE and EERI 2018 Annual Meeting. To learn more about the EERI/FEMA NEHRP Graduate Fellowship, visit this link: https://www.eeri.org/about-eeri/honors-awards/graduate-fellowship/
