Larger earthquakes generate their own media these days. But inquires about the South Napa, California earthquake prompted me to return [briefly] to this blog with a short list of suggested resources related to the event.
Both California Governor Gerry Brown and U.S. President Barack Obama declared an emergency and a major disaster for Napa and Solano counties. Property damage is fairly modest (about US$ 300 million at this time and rising slowly, but well down from a preliminary US$ 1 billion estimate on August 25) although some serious structural and non-structural building damage to older, masonry structures in particular occurred. Casualties are limited to one mortality. Bridge damage appears minimal and other lifeline interruptions appear moderate to light. Cases of soil liquefaction are remarkably rare.
A Pacific Earthquake Engineering Research (PEER) Center Reconnaissance team reported some preliminary observations on Monday, September 15, 2014 in a joint PEER – Earthquake Engineering Research Institute (EERI) briefing . The Geotechnical Extreme Event Reconnaissance (GEER) released an electronic reconnaissance report following their extensive geotechnical observations in the epicentral area. Recently PEER published its preliminary reconnaissance report (PEER 2014/13) of the event. The processed strong motion recordings for the event have been available for some time from CESMD.
