Friday, 14 May 2021 | Part 1 - Base Isolation

The Third Kenji Ishihara Colloquium Series on Earthquake Engineering includes a series of three webinars on the topics of Base Isolation, Damping Systems and Soil-Structure Interaction. Three distinguished panelists will be invited to each webinar for a 20-minute presentation each and will be followed by a discussion with questions and answers under the lead of a moderator. This series of webinars targeted structural and geotechnical engineers, architects, students, researchers and building officials. The Kenji Ishihara Colloquium Series on Earthquake Engineering is hosted by the EERI San Diego Regional Chapter. Part 1 speakers included Reid Zimmerman, KPFF; Henry Tatham, Beca; and Michael Constantinou, University at Buffalo.

This webinar, hosted by the Alaska EERI regional chapter, covered the history of seismicity and resilience planning for the state, reviewed tools and guidance that the EERI Public Policy and Advocacy Committee has recently developed for Citizen and Regional Chapter Advocacy, and discussed actions the membership can take today for a seismically safer Alaska. Speakers included Jessica Feenstra, President of the Alaska EERI chapter; Zahraa Saiyed, Co-Chair of the EERI Public Policy and Advocacy Committee; Sterling Strait, Chair of the Alaska Seismic Hazards Safety Commission; and Mike West, Alaska State Seismologist.

The EERI Northern California Regional Chapter and the EERI Learning from Earthquakes Program hosted this webinar on the multiple massive temblors (M8.1, M7.4, M7.3) that occurred in the South Pacific Ocean in early March 2021. The March 5, 2021 M8.1 event was one of the strongest quakes to strike the region in modern history. Earthquakes of this size are capable of creating tsunamis (ocean waves) that can travel thousands of miles causing widespread damage to coastal communities. The quakes were centered northeast of New Zealand. Tsunami warnings were issued throughout the region and as far away as Chile forcing thousands of people to evacuate coastal areas. Fortunately, only small wave surges (about 30 cm) were observed causing little damage. This webinar discussed seismology, tsunamis mechanisms and warning systems. Speakers included Rick Wilson, CGS, and William Power, GNS Science.

This webinar, organized by the EERI San Diego Chapter, provided background and further information on the preliminary review maps of proposed new and revised Alquist-Priolo Earthquake Fault Zones to the City and County of San Diego that were released by the California Geological Survey (CGS) on February 18, 2021. The release by CGS began a 90-day public comment period to provide technical review comments on the proposed Earthquake Fault Zone maps. This webinar helped attendees feel better informed to provide review comments on the maps to the State Mining and Geology Board. Presenters included Thomas Rockwell, Timothy Dawson, and Micahel DeFrisco.
