Earthquake activity this week

Use the graph and map below to explore the earthquake activity during the past seven days in southern California. This is a change to the previous display, we now show a rolling seven day period rather than a fixed Thursday to Thursday week. For further information, links will take you to the USGS page for each event. Events are color-scaled by the time they occurred (blue is early in the period, red is late) and size-scaled by their magnitude.

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.
