Newberry earthquakes, 2011 - 2013 Map showing earthquakes located within the Newberry caldera from 2011 - 2013. Earthquakes from April 08-12, 2013, are colored orange or red (for April 12 events) (map: USGS)
Newberry (Oregon): A cluster of earthquakes has occurred during the past days under the caldera. USGS reports:
"Between 8-12 April, five earthquakes were located within or along the margins of the Newberry caldera by the Pacific Northwest Seismic Network (PNSN, www.pnsn.org). The first two occurred at 04:19 & 04:20 PDT on 04/08 and were followed over the next 20 minutes by eight smaller (and therefore unlocatable) earthquakes.
