A New Look for The Pulse and EERI Calendar of Events

eeri logo 3.5x3.5 with backgroundDid you notice that The Pulse newsletter has a new look? The Pulse has been redesigned to be more modern and sleek, easier to read, and to adapt to different devices. We think it makes our overall brand more cohesive and identifiable for our membership, our Board, and our community.

The newsletter is a place for us to showcase our work and connect with each other. To enhance that goal, we've also updated our Calendar of Events.  EERI has created its own Google calendar for events that you can add to your computer, tablet or phone to ensure you have the latest updates. Scroll down to view the calendar and directions for adding it to your device(s). You can also view the calendar on our website.

We've also added something special for those who fondly remember when The Pulse was printed and mailed. Soon to be released is Pulse Digest, a twice-yearly printed collection of recent Pulse articles. EERI regular, affiliate, retired and young professional members will recieve a copy, as well as student members with a domestic U.S. mailing address. Be sure to open the envelope when it arrives in your mailbox for your free EERI sticker!

We invite you to share your upcoming events, announcements, opportunties, and major achievements with us. We also welcome your comments and feedback on the new look.

Vitor Silva to Receive 2017 EERI Shah Family Innovation Prize

Thanks to a generous gift from the Shah family, EERI annually awards the Shah Prize to young professionals and academics for creativity, innovation, and entrepreneurial spirit in the field of earthquake risk mitigation and management. 

Vitor Silva (M. EERI, 2014) has been awarded the 2017 EERI Shah Family Innovation Prize.  Vitor Silva is the Seismic Risk Coordinator at the Global Earthquake Model (GEM) Foundation, a non-profit organization with the goal to calculate and communicate earthquake risk worldwide. He has participated in studies in structural vulnerability and probabilistic seismic risk assessment in dozens of countries such as Portugal, Iran, Peru, Colombia, Costa Rica, and Canada. He is currently leading or participating in international programs supported by the Global Facility for Disaster Reduction and Recovery of the World Bank, the European Commission, and the United States Agency for International Development, which aim at improving the understanding of earthquake risk in regions such as Central America and the Caribbean, Europe, Sub-Saharan Africa and South-East Asia. His activities also focus on the development of tools for seismic risk assessment, and databases of vulnerability and exposure models for multi-hazard risk analysis. 

As part of his role at the GEM Foundation, Vitor has conducted workshops to improve the local capacity in assessing the impact from earthquakes in various parts of the world (e.g. Pavia, Kathmandu, Bogota, Medellin, Santiago, Lima, Addis Ababa, San Jose) for more than 300 participants from 43 countries. Vitor serves as an Associate Editor of Earthquake Spectra, he is a member of the executive committee of the World Housing Encyclopedia, and has documented his research in more than 80 publications in international peer-reviewed journals, conference proceedings and book chapters.

The 2017 Shah Family Innovation Prize will be presented at EERI's 2018 70th Annual Meeting, held during the 11th National Conference on Earthquake Engineering (11NCEE) in Los Angeles, CA. To learn more about the Shah Family Innovation Prize, please visit the EERI website.

EERI Members Elected to the National Academy of Engineering

The EERI Board of Directors is honored to congratulate two longtime members, Peter Fajfar (M.EERI,1981) and Norman A. Abrahamson (M.EERI,1984), for election to the National Academy of Engineering (NAE).

Peter Fajfar is a professor of structural and earthquake engineering, Faculty of Civil and Geodetic Engineering, University of Ljubljana, Ljubljana, Slovenia. The NAE has recognized Dr. Fajfar for "leadership in the development of nonlinear structural analysis methods for earthquake engineering."

Norman Abrahamson, chief engineering seismologist, Pacific Gas & Electric Co., was recognized for "contributions to seismic hazard assessment and for leadership in engineering seismology and earthquake engineering."

Election to the National Academy of Engineering is among the highest professional distinctions accorded to an engineer.  Academy membership honors those who have made outstanding contributions to "engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature" and to "the pioneering of new and developing fields of technology, making major advancements in traditional fields of engineering, or developing/implementing innovative approaches to engineering education."

In February, the NAE announced the election of Fajfar and Abrahamson among 83 new members and 16 new foreign members.  This brings the total U.S. membership to 2,293 and the number of foreign members to 262. Individuals in the newly elected class will be formally inducted during a ceremony at the NAE's annual meeting in Washington, D.C., on Sept. 30, 2018.

Preliminary Reconnaissance Report on M7.3 Ezgele, Kermanshah, Iran Earthquake on November 12, 2017



The earthquake of the evening of November 12, 2017 with a moment magnitude of 7.3 was one of the most destructive earthquakes over the past two decades in Iran. This earthquake was felt over more than a half of the country and resulted in a large number of casualties in Kermanshah province (436 people according to the latest statistics published) in addition to extensive financial losses. This report includes reconnaissance observations on the performance of steel structures, concrete structures, masonry structures, nonstructural components, and also social and organizational aspects of the earthquake impacts.
