Learning From Earthquakes
Recordings and Q&A from the Kahramanmaraş Earthquakes Reconnaissance Briefing Webinars
In May, Learning From Earthquakes (LFE) hosted a weekly webinar series featuring briefings from the three LFE teams that traveled to Turkey to collect reconnaissance data on the impacts to lifelines, hospitals, and buildings from the February 6 2023 Kahramanmaraş Earthquake Sequence. A fourth webinar featured members of the Geotechnical Extreme Events Reconnaissance (GEER) Association's reconnaissance teams and focused on geotechnical impacts. Video recordings of all the webinars, as well as the March webinar with members of the joint LFE-GEER advance reconnaissance team, are now available as a playlist on EERI's YouTube account here. Copies of the written questions and speaker responses from each webinar are also available on the LFE virtual clearinhouse website in the Resources section (select a webinar recording entry and click on the "Read webinar Q&A" link below the embedded video for a PDF of the Q&A).
Thank you to all the speakers, team leads, team members, and moderators for contributing to this series! LFE is planning an additional webinar later this summer focusing on the impacts of the earthquakes in Syria. Stay tuned for announcements in future editions of the Pulse.Back to top >

YMC Webinar: Training and Communication for Earthquake Risk Assessment Project and Applications for Urban Risk Assessment
Wednesday June 7, 2023
10:00-11:30 AM Pacific Time
EERI’s Younger Members Committee (YMC) invites you to a FREE webinar on the the Training and Communication for Earthquake Risk Assessment (TREQ) project and urban risk assessment. Experts from GEM, PartnerRe, and USGS will introduce TREQ, which aims to demonstrate how earthquake hazard and risk assessment can inform decision-makers in the development of risk reduction policies, as well as how earthquake risk can be properly communicated to stakeholders and the public in general. The project is organized into two main parts. The first one aimed to develop capacity for urban earthquake hazard and risk assessment in Latin America, Quito (Ecuador), Cali (Colombia), and Santiago de los Caballeros (Dominican Republic); while the second part developed training, educational and communication material to enhance the understanding of earthquake risk worldwide.
Moderator: Prajakta Jadhav, University of British Columbia
- Catalina Yepes-Estrada, Senior Risk Scientist, GEM Foundation
- Kendra Johnson, Seismic Hazard Analyst, GEM Foundation
- Robin Gee, Seismic Hazard and Risk Modeler, PartnerRe
- Alejandro Calderón, Seismic Risk Engineer, GEM Foundation
- Kishor Jaiswal, Research Civil Engineer, USGS
- Robert Chase, Research Civil Engineer, USGS

Reminder: Call for Papers for Spectra Special Collection on Turkey Earthquakes
The 2023 Kahramanmaraş earthquakes occurred in a region of significant prior study by Earthquake Spectra authors. In recognition of this legacy of work, Earthquake Spectra has compiled a special collection of some previously published papers from this region. These papers can be found at the collection page here, and will be freely available to readers for until November 1, 2023.
In addition, Earthquake Spectra is opening a new special collection: Impact of the February 6, 2023 M7.8 and M7.6 Earthquakes in Turkey on the Built Environment, and Implications on Seismic Hazard
Two devastating earthquakes occurred within 9 hours of each other on February 6, 2023 in Turkey, along the Southern part of the Eastern Anatolian Fault Zone. The ruptured fault segments, exceeding 300 km in total length, had been silent since 1511. The impacts of these two sequential earthquakes were enormous: the number of people who lost their lives in 240,000 collapsed or severely damaged buildings in eleven provinces has exceeded 50,000. More than 500 strong motion stations in Turkey have recorded the ground motions. Earthquake Spectra invites earthquake researchers to contribute to its “Special Collection” for sharing their valuable observations and discussing all aspects of these earthquakes. This Special Collection will include original articles on topics including (but not limited to) reconnaissance reports, characteristics of fault ruptures, analysis of ground motions, site amplification, geotechnical deformations, performance of buildings and infrastructure, economic losses, risk analysis, and insurance issues.
EERI would like to announce this collection on the one-year anniversary of the earthquakes in February 2024. To be included in this announcement, papers should be submitted no later than October 1, 2023, though submissions will continue to be accepted on a rolling basis after that date and added to the collection once published.
For the list of guest editors and more information on the submission process, visit the news post on the EERI website here.
Don't Miss the May Issue of Earthquake Spectra!
Have you explored the May 2023 (Volume 39, issue 2) issue of Earthquake Spectra? Editor-in-chief Jack Baker selected "Seismic loss and resilience assessment of tall-coupled cross-laminated timber wall building," by Tian You, Biniam Tekle Teweldebrhan, Wei Wang, and Solomon Tesfamariam, as the editor's choice paper for this issue.
Editor's Recommendation: “You et al perform an integrated response history analysis and FEMA P-58 loss assessment to quantify the seismic performance of a tall cross-laminated timber wall building. The study involved developing an OpenSEES model of a 20-story case study building, performing incremental dynamic analysis using 30 pairs of ground motions, and using the FEMA P-58 methodology to compute repair costs and repair times. Analyses show that the structural repair costs are dominated by damage to steel coupling beams. Fortunately, these coupling beams are more easily replaceable than many of the other structural components in the building. The study is noteworthy for the holistic analysis of a structural system that is of significant interest at present, providing helpful insights and demonstrating the utility of the FEMA P-58 loss assessment methodology.”

Kinemetrics Webinar: Looking Inside the Earth and Planets
Join Kinemetrics on June 7 (9:00 AM Pacific) for a free webinar: “Looking Inside the Earth and Planets: Improved Coverage, Advanced Instrumentation, and Innovative Methods.” Global seismology has come a long way in providing insights into Earth's internal structure and dynamics. However, progress in imaging the Earth's inner core has been impeded by the lack of geometric coverage of body waves from large earthquakes. It was only recently confirmed that its innermost part contains distinct seismic anisotropy. Further experiments with earthquake coda correlation contributed to the rise of a new paradigm—the coda-correlation wavefield, utilized for important studies of the Earth and Mars cores. In this webinar, Professor Hrvoje Tkalčić of the Research School of Earth Sciences at Australian National University will show how coda-correlation studies— and further development and the proliferation of seismic sensors—can play a central role in global and planetary seismology in the coming decades. Register here to attend the webinar!
