Joint EERI-GEER Webinar: 2023 Kahramanmaraş Turkey Earthquake Sequence Reconnaissance Briefing

Joint EERI-GEER Webinar: 2023 Kahramanmaraş Turkey Earthquake Sequence Reconnaissance Briefing

Monday, March 20
11:00 AM-12:00 PM Pacific Standard Time

EERI's Learning from Earthquakes Program and the Geotechnical Extreme Events Reconnaissance (GEER) Assoication invite you to a FREE reconnaissance briefing webinar on the 2023 Kahramanmaraş earthquake sequence in Turkey.

golbasiOn February 6, 2023, a M7.8 earthquake occurred in southern Turkey near the northern border of Syria, followed about 9 hours later by a M7.5 earthquake approximately 90 km to the north of the first. The impacts of these earthquakes were devastating. The number of fatalities in both countries has risen to more than 50,000. According to Turkish government sources, more than 200,000 buildings collapsed or suffered damage severe enough to require demolition. Over a million people have been displaced as a result.

A joint EERI-GEER advance reconnaissance team conducted field visits in the disaster zone in southern Turkey from February 15-20. The team traveled over 1,500 km in the affected areas, first along a north-to-south path, and then east-to-west in the southern third of the region. They collected perishable geotechnical data, made observations of structural damage, and assessed needs and opportunities for future reconnaissance.

The four members of the team will present initial findings on topics including surface fault rupture and liquefaction, impacts to structures and lifelines, and emergency response. As the team was unable to visit Syria, the webinar will focus on impacts in Turkey.

YMC Webinar: Real-time Hybrid Simulation for Earthquake Induced Motions and Cascading Earthquake and Tsunami Events

Wednesday, March 8, 2023
12:00-1:00 PM Pacific Time

Join EERI’s Younger Members Committee for a FREE webinar on Real-time hybrid simulation for earthquake induced motions and cascading earthquake and tsunami events, featuring two speakers:

  • Dr. Barbara Simpson, Assistant Professor, Stanford University
  • Dr. Liang Cao, Advanced Technology for Large Structural Systems (ATLSS) Engineering Research Center, Lehigh University

The first presentation will focus on real-time hybrid simulation (RTHS), a cost-effective cyber-physical simulation method that can be used to examine the behavior of systems too large or complex to test fully in a laboratory setting, alleviating the aforementioned constraints. Hydrodynamic-RTHS, or hydro-RTHS, couples physical waves and a partial structural specimen with a computational structural model in the NHERI-EF Large Wave Flume and Multi-Direction Wave Basin at Oregon State University (OSU). The second presentation will focus on recent developments of new types of high-performance control systems (HPCSs), including robust semi-active friction devices. The vibration mitigation performance of HPCSs is investigated through Real-time Hybrid Simulations (RTHS) on an earthquake-excited two-story reinforced concrete building.

Quick Quake Briefing: Indonesia M5.6 Cianjur Earthquake of 21 November 2022

Thursday February 16, 2023
4:00-5:00 PM Pacific Time

The EERI Northern California Regional Chapter is hosting a FREE webinar on the M5.6 earthquake that struck West Java in Indonesia. 

Cianjur earthquake damage

The earthquake struck near Cianjur in West Java. Between 330 and 640 people died, and over 7,700 were injured. More than 63,000 homes were damaged across the region. The earthquake was strongly felt in the Indonesian capital Jakarta, over 100 km (63 mi) to the North. It is the deadliest earthquake to hit Indonesia since the 2018 Sulawesi earthquake.

Damage evaluated after the quake indicated a maximum Modified Mercalli intensity of VIII (Severe). According to the Meteorology, Climatology, and Geophysical Agency (BMKG), the earthquake had a strike-slip focal mechanism at a depth of 11 km (7 mi), classifying it as a shallow event. Despite the moderate size of the earthquake, its shallow depth caused strong shaking. The National Agency for Disaster Countermeasure (BNPB) described the damage to homes and buildings as "massive."

Two speakers will be joining from Indonesia:

  • Dr. Nuraini Rahma Hanifa, a previous EERI Housner Fellow now with the Research Center for Geological Disaster, Research Organization of Earth Sciences and Maritime, National Research and Innovation Agency (BRIN), will present an overview of the earthquake and its aftermath.
  • Dr. Sigit Pramono of the Engineering Seismology Earthquake Early Warning System Division, Meteorological Climatological and Geophysical Agency (BMKG) will present on the engineering seismology aspects.

Ferndale M6.4 Earthquake Reconnaissance Briefing Webinar

Thursday, February 9, 2023
11:00 AM-1:00 PM Pacific Time

EERI's Learning from Earthquakes Program and the California Earthquake Clearinghouse invite you to a FREE reconnaissance briefing webinar on the earthquake that struck Humboldt County, California in December.


At 2:34 AM on December 20, 2022, a M6.4 earthquake struck offshore near Ferndale, California, causing damage to lifelines and structures in Humboldt County. Structures in the nearby communities of Ferndale, Fortuna, and Rio Dell experienced damage including broken windows, collapsed chimneys, and fallen bricks, and a small number of buildings slid off their foundations. Roughly 150 homes were damaged or destroyed in the earthquake. More than 70,000 people lost power, and there was damage to roads and bridges in the area. The ShakeAlert earthquake early warning system was activated, and approximately three million people in northern California and southern Oregon received warnings.

In this multidisciplinary webinar, speakers will provide information on the science, engineering, and emergency response aspects of the earthquake, and discuss the impact on lifelines and critical infrastructure, including electricity, transportation, and healthcare facilities.

Speakers include:

  • Cynthia Pridmore, California Geological Survey
  • Jason Patton, California Geological Survey
  • Richard Allen, Berkeley Seismological Laboratory and MyShake
  • Maggie Ortiz-Millan, Earthquake Engineering Research Institute
  • Megan Stanton, Pacific Gas and Electric
  • Bob Tanaka and Richard Heninger, Caltrans Division of Engineering Services
  • Speaker TBD from California Department of Health Care Access and Information

Additional speakers will be announced soon. PDH certificates will be available upon request.

2022 Taiwan Earthquakes Reconnaissance Briefing Webinar

January 11, 2023
3:00-4:00 PM PST


The Earthquake Engineering Research Institute (EERI) and the National Center for Research on Earthquake Engineering (NCREE) in Taiwan invite you to a free reconnaissance briefing webinar on the earthquakes that struck Taiwan in September 2022.

Taiwan earthquake train derailment

On September 18th, 2022, at 2:44 pm local time, a moment magnitude 6.9 earthquake struck 42.7 km north of Taitung City, Taiwan. The earthquake followed a magnitude 6.5 earthquake in the same area the previous day. The M6.9 earthquake caused both geotechnical failures and damage to infrastructure, mainly bridges, railroads, and highways. Damage to buildings was primarily concentrated on older non-ductile structures, as well as non-structural component damage. At least one building collapsed and hundreds more suffered some damage. The earthquake resulted in at least one death and 171 injuries.

The earthquake highlighted the vulnerabilities of older non-ductile concrete buildings in seismic regions, concrete bridges, and non-structural building components during an earthquake. This webinar will provide an overview of the event, including the earthquake seismology, emergency management, and geotechnical and structural engineering impacts.
