Map of the Oroville Dam showing location Feb 14, 2017 earthquake

aerial map showing lake, dam, and land around it with earthquakes plotted as circles

Detailed Description

Map of the Oroville Dam showing maximum‐likelihood location of the 14 February 2017 MD 1.0 event (confidence ellipsoid east–west: 2.6 km; north–south: 0.8 km; vertical: 1.6 km). Lines represent the particle‐motion backazimuths for the 10 largest magnitude events in February 2017. The maximum‐likelihood location of the 25 April 2017 controlled blast (star) (confidence ellipsoid east–west: 3.7 km; north–south: 1.8 km; vertical: 2.2 km) and the true blast location (circle) are also shown.
