Join EERI's San Diego Chapter for the 2023 Kenji Ishihara Colloquium: Advancing Earthquake Engineering in the Wake of the Turkey-Syria Earthquake. This year's colloquium will take place virtually, as a webinar series on the lessons learned from the 2023 Kahramanmaraş, Turkey Earthquake Sequence. Researchers, expert engineers and social scientists will come together in this Kenji Ishihara colloquium to discuss structural engineering and the far-reaching social implications of the Turkey earthquake sequence. Experts will share their insights on the lessons learned from the Turkey earthquake and how these are shaping the future of earthquake engineering, disaster preparedness, and response to enhance engineering practices and expedite seismic functional recovery.

The webinars will take place on Thursday October 5, Thursday October 12, and Friday October 27, each starting at 11:00 AM Pacific Time. The webinar lengths will vary by session but will run no later than 2:00 PM. Registering once at the link above will allow you to attend all the sessions.

The EERI Northern California Regional Chapter is hosting a FREE webinar on the earthquakes that struck Turkey. The topic deals with how earthquake losses are covered by insurance in Turkey and contrast to that in United States.

On 6 February 2023, a M7.8 earthquake struck southern and central Turkey and northern and western Syria. It was followed by a M7.5 earthquake later the same day. There was widespread damage and tens of thousands of fatalities. The total cost of earthquake damage in Turkey was estimated by TÜRKONFED at $84 billion US dollars ($71B on rebuilding, $10B loss in national income, and an additional $3B loss in workforce). The Turkish government released a preliminary report estimating the total damage cost at $103.6 billion, corresponding to 9 percent of its GDP in 2023. About half of residential property in the affected area is thought to be covered by Turkish Compulsory Earthquake Insurance (source: Wikipedia).

Speakers:

• Dr. Ufuk Yazgan is a Professor at Istanbul Technical University, and will pro-vide an overview of the damage to the building stock.
• Mr. Erdem Karabostan is the General Manager at the Turkish firm T-Rupt that advises on loss estimates for the Turkey Reinsurance Industry. He will explain how the insurance industry operates and responded to the earthquakes.
• Dr. Patxi Uriz is a Director at Moody’s Risk Management Solutions (RMS) Corporation (USA) focusing on catastrophic risk management. Dr. Uriz leads the earthquake and wildfire vulnerability teams at Moody’s RMS. He will contrast the Turkish and US construction and insurance practices.

The webinar will include time for participants to ask questions of the speakers.

EERI’s Younger Members Committee (YMC) invites you to a FREE webinar on August 30th! This webinar will introduce and summarize a series of tools that Pacific Gas and Electric Co (PG&E) is developing for performing regional risk assessments in the San Francisco Bay Area. These tools are developed for earthquake scenarios that capture the spatial correlation of realistic ground motions associated with a rate of occurrence at each selected location. Amongst others, the speakers will discuss (1) a raster-based landslide model based on multi-modal analysis that provides the likelihood of earthquake-induced slope failure and estimated runout, calibrated based on historical data; (2) a raster-based model of liquefaction that provides likelihood, vertical settlement, and lateral displacement, based on a 3D geological model, a CPT and SPT dataset, and an updated regional groundwater model; and (3) an example application that highlights the importance of correlated ground motion for quantifying risk and impact of risk attitude on the risk scores. These tools will help prepare for earthquakes in the Bay Area.

Speakers:

• Dr. Alidad Hashemi, Hashemi & Elkhoraibi Earthquake Engineering Inc.
• Dr. Melanie Walling, GeoEngineers
• Dr. Nico Kuehn, UCLA
• Dr. Michael Greenfield, Michael Greenfield Engineering
• Dr. Albert Kottke, Pacific Gas & Electric
• Moderator: Renmin Pretell, University of Nevada, Reno

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

Speakers:

• 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

EERI's Learning From Earthquakes (LFE) Program invites you to a FREE webinar series this month with the LFE and GEER reconnaissance teams that traveled to Turkey in March to assess the impacts of the February 6, 2023 Kahramanmaraş Earthquake Sequence.

GEER Kahramanmaraş Earthquakes Reconnaissance Webinar: Geotechnical Impacts

Tuesday, May 30, 2023
10:00 AM-11:30 AM Pacific Time
REGISTER HERE 

On May 30, in the final webinar in this series, the Geotechnical Extreme Events Reconnaissance (GEER) Association will share reconnaissance findings on the geotechnical impacts of the February 6, 2023 earthquake sequence. GEER and EERI sent an advance reconnaissance team to Turkey in mid-February, a week after the earthquakes, to collect perishable data and identify areas for further research. A Phase I GEER team followed to collect data along extensive fault ruptures, inspect affected dams, and map areas with variable levels of liquefaction-related damage. A Phase II GEER team later performed reconnaissance of liquefaction-related damage to port facilities and foundations. Members of all teams will join the webinar to present on their findings and respond to questions from the audience.

Moderator: Jonathan Stewart, UCLA

Speakers:

• Kemal Önder Çetin, Middle East Technical University
• Özgür Kozacı, Pacific Gas & Electric
• Tristan Buckreis, UCLA
• Diane Moug, Portland State University
• Kristin Ulmer, Southwest Research Institute
• Robb Moss, California Polytechnic State University San Luis Obispo
• David Frost, Georgia Institute of Technology

Registering once at the above link will allow you to attend any of the webinars in the series.

PDHs for each webinar will be available at no charge to EERI members, and at a fee of $35 per webinar for non-members.
