It is funded by the U.S. Geological Survey (USGS) and the California Office of Emergency Services (CalOES). Its primary mission is to distribute data recorded or processed by the SCSN, a component of the California Integrated Seismic Network (CISN). Recent Earthquakes in the Southern California Region Use the map below to explore recent earthquake activity. This map shows the earthquake feed from the USGS for all earthquakes in the last 7 days with the network codes of CI, NC, or NN, or between the latitude coordinates 32 and 42 and the longitude coordinates -126 and -114. The reporting region of the SCSN is shown enclosed in the orange polyon. Expand the left sidebar to view the event listing; selecting an event will highlight its map location. Once selected, for further information, clicking an event ID (e.g. ci38354200) link will take you to the detailed page for that event. Events are color-scaled by the time they occurred (red: within 1 hour; blue: within 1 day; yellow: within 7 days; grey: older) and size-scaled by their magnitude, as represented in the legend below. The map updates every 5 minutes with the most recent earthquake data available, the same refresh rate as the USGS earthquake feed. Please note that not all earthquake information displayed on this map may have been reviewed by a seismologist, and automated solutions are likely to be updated. sidebar-v2 The SCSN reporting region is enclosed in the orange polygon.
