Recent Earthquake Activity Click for more info

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 within the SCSN reporting region.

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 USGS 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.
