In response to the 2019 Ridgecrest Earthquake Sequence, the California Earthquake Clearinghouse activated and established a physical clearinghouse location in Ridgecrest, CA from July 5 to July 9, 2019. Over the course of the weeklong activation, the scientific and engineering communities came together in clearinghouse briefing calls to coordinate, collaborate, and share information.
On August 14, 2019, the California Earthquake Clearinghouse hosted the Ridgecrest Earthquake Sequence Reconnaissance Briefing Webinar. The webinar provided an overview of the earthquakes, geological observations, Geotechnical Impacts, and Structural Engineering Impacts.
Many clearinghouse participants contributed to the Ridgecrest Earthquake Sequence Reconnaissance Report. This report captures reconnaissance findings from the first months following the main shock and includes sections from over 30 contributors. The multi-disciplinary report includes sections on geosciences, geotechnical impacts, lifelines, structural impacts, emergency response, clearinghouse operations, and data collection methods and products. The report features a close look at the extent of damage to manufactured homes, which emphasized the vulnerability of these structures, given the limited occurrence of damage to structures overall in the City of Ridgecrest. The report also includes several sections on data collection methods and products that show progress in collecting and coordinating post-earthquake data.
8 months after the earthquake sequence began, a series of one-year anniversary sessions were held as part of the 2020 National Earthquake Conference. The session topics included Science Findings and Lessons, Engineering Findings and Lessons, a poster session, and several other presentations.
The Ridgecrest Earthquake Sequence Virtual Clearinghouse Website contains more information about the earthquake, including, reports, updates, links, and information about how to contribute data. The site continues to be updated.
