Improving Earthquake Resiliency Through the Use of Post-Earthquake Clearinghouses

Thursday, November 14, 2019

Since 2000, there have been 51 significant earthquakes that have caused over $3.4 billion dollars in damages and 31 deaths in the United States.1 While large earthquakes pose a substantial threat along the West Coast and in Alaska, they also can affect the Central and Eastern United States, as they did during the 1811 and 1812 New Madrid earthquakes and 1886 Charleston, SC earthquake. Earthquakes can have wide ranging impacts, such as the 5.8 magnitude earthquake in Mineral, VA that happened in 2011 and was felt across multiple states along the East Coast, causing $200-$300 million in damages and this year’s 7.1 magnitude earthquake near Ridgecrest, CA that was felt in Nevada and Arizona, and cased $100 million in damages.1,2,3 A single event can be devastating: for example, the 1994 Northridge, CA, 6.7 magnitude earthquake caused at least $40 billion in direct damage and killed around sixty people.3

As population continues to expand into risk-prone areas, improved risk management practices are increasingly necessary to improve emergency preparedness and response by providing information on earthquake processes, assessing the adequacy of built infrastructure and building codes, and providing insight on how to improve future recovery and urban development efforts. Post-earthquake technical clearinghouses are a successful strategy for tracking the collection of information about ground failures, structural damage, and other impacts from major earthquakes, reducing duplication of effort in data collection, and disseminating information about events to emergency response managers. In this webinar, our speakers discuss earthquake risk in the U.S., the importance of coordinated post-earthquake response, and the effectiveness of post-earthquake technical clearinghouses in improving earthquake resiliency.

President Trump approves earthquake hazards bill

Cracked road from earthquake

On December 11, President Donald Trump signed a bill to reauthorize the National Earthquake Hazards Reduction Program (NEHRP) through fiscal year 2023. The bill provides the first reauthorization of NEHRP since 2004, while clarifying the responsibilities of the National Institute of Standards and Technology (NIST), the Federal Emergency Management Agency (FEMA), the National Science Foundation (NSF), and the United States Geological Survey (USGS) in carrying out the program. It also calls for a comprehensive assessment of the nation’s earthquake risk reduction strategy.

Congress reauthorizes national earthquake hazards program

Cracked road from earthquake

A bill to reauthorize the National Earthquake Hazards Reduction Program (NEHRP) through fiscal year 2023 passed the House on November 27 and now awaits final approval by the President. The National Earthquake Hazards Reduction Program Reauthorization Act of 2018 (S. 1768) serves as a follow-up to the Earthquake Hazards Reduction Act of 1977, which established NEHRP as the nation’s interagency platform for seismic hazards.
