Lawrence Berkeley Nat’l Lab: New Sensor Could Shake Up Earthquake Response Efforts

After the most recent series of earthquakes in Southern California, Lawrence Berkeley National Labs has put out a news release describing their recent work (in conjunction with University of Nevada-Reno) developing optical sensor technology that can be used to speed up the time needed to evaluate the post-earthquake damage to buildings, and assess whether they are safe enough to enter or require red-tagging.

For more information, the full article can be found on the Lawrence Berkeley National Lab website.

The National Development Council has provided their final report to the City of Seattle on URM retrofit funding. With the completion of this report, along with the recommendations of the URM Policy Committee, the City will begin developing high-level policy recommendations to the Mayor’s Office for their review later this year.

The report is available on the Seattle Department of Construction and Inpections’ Unreinforced Masonry Buildings website.

The city continues to be interested in hearing your thoughts on this issue. You can contact the URM Policy Committee at: SCI_URM_Policy_Committee_Comments@seattle.gov

AIA Oregon: URM Seismic Resilience Symposium

EERI Washington Chapter members may be interested in attending The American Institute of Architects Oregon Chapter’s URM Seismic Resilience Symposium. Event details are included below:

URM Seismic Resilience Symposium
July 18-20, 2019 

Unreinforced Masonry (URM) buildings present a challenge for earthquake-prone communities. There are over 1,650 URM buildings in Portland and millions around the world. These structures are important historic, architectural, cultural, and economic landmarks, but their vulnerability to earthquakes imperils them and the people that live and work in them.

The URM Seismic Resilience Symposium, July 18-20, 2019, is a three-day event for architects, engineers, owners, property managers, and anyone that might deal with URM buildings. AIA HSW and Engineering continuing education credits will be available.

Visit the AIA Oregon website for details on the agenda, speakers, and special events.

Registration is now open.

The Seismological Society of America will be hosting a town hall meeting on earthquake early warning systems in the Pacific Northwest as part of their 2019 Annual Meeting in Seattle. This event is free to attend!

For more information, please visit the Seismological Society of America Website

The Why, How, Where and What of Earthquake Early Warning Tuesday, 23 April 6-7:30 p.m. Westin Seattle, Rooms Cascade I & II Why should we prepare for earthquakes in the Pacific Northwest? How could seconds of warning help make us less vulnerable to damage and injury? How do earthquake early warning (EEW) systems work, and when might we have one?

Seismic Landslide Assessments: Bridging the Gap between Engineers and Earth Scientists

Earthquake-induced landslides represent a significant seismic hazard, as evidenced by recent earthquakes in Kaikoura, New Zealand and Gorkha, Nepal, and proper planning/mitigation requires accurate evaluation of the potential for seismic landslides.
Engineers often tackle this problem through a detailed evaluation of individual slopes and more recently have introduced performance-based engineering (PBE) concepts into the analysis.
Recognizing the compounding effects of multiple landslides across an area, earth scientists often evaluate seismic landslides at a regional scale. This approach sacrifices details, but provides a broader assessment of the impacts of earthquake induced landslides.
This presentation will describe the integration of performance-based engineering concepts into regional-scale seismic landslide assessments. The basic PBE framework for seismic landslides will be introduced along with the modifications required to apply it at a regional scale. The application of the approach for a seismic landslide hazard map will be presented. The use of seismic landslide inventories to validate regional landslide assessments will be discussed, along with advancements in developing seismic landslide inventories using remote sensing techniques.
Finally, research needs required to further advance regional seismic landslide assessments will be presented.


Ellen M. Rathje is the Warren S. Bellows Centennial Professor in the Department of Civil, Architectural, and Environmental Engineerin
g and also a Senior Research Scientist at the Bureau of Economic Geology at the University of Texas at Austin. Her research interests include seismic site response analysis, earthquake-induced landslides, field reconnaissance after earthquakes, and remote sensing of geotechnical phenomena.

She is a founding member of and current co-chair of the Geotechnical Extreme Event Reconnaissance Association (GEER) which coordinates National Science Foundation-sponsored geotechnical investigations around the world after major earthquakes and other natural disasters such as floods, to advance research and improve engineering practice. Rathje is also the Principal Investigator of the DesignSafe cyberinfrastructure project, a web-based research platform for the National Hazards Engineering Research Infrastructure (NHERI) that provides computational tools to manage and analyze critical data for natural hazards research. Closer to home, Rathje is co-principal investigator for the Center for Integrated Seismicity Research and the TexNet Seismic Monitoring Program, both housed at the Bureau of Economic Geology at UT.


The William B. Joyner Lecture is jointly awarded by EERI and SSA to those who have provided outstanding earth science contributions to the theory and practice of earthquake engineering or outstanding earthquake engineering contributions to the direction and focus of earth science research—together with demonstrated skills of communication at the interface of earthquake science and earthquake engineering.
