Up-to-the-minute Southern California
Due to a variety of maintenance and technical issues, the earthquake lists used by this page uses are
no longer being updated, making this map functionally worthless.
It will be taken down or replaced with a referring link in the near future.
At some point we may take another stab at developing a replacement for "webquakes" but there is nothing
planned at this time.
Please visit the Recent Earthquake Activity site hosted by the
Southern California Earthquake Center (SCEC) for accurate and current earthquake information.
Thanks you for visiting this page and sorry for any inconvenience.
This map shows the last approximately 500 earthquakes detected
by seismographs in southern California.
Earthquake locations are updated based on Caltech's
real-time picker. These locations are received over e-mail,
usually within a few minutes of the earthquake's occurrence.
Note that since these locations have not been human-reviewed,
they may contain errors.
- To zoom in on an area: Click and drag a rectangle with the mouse around the area to zoom in on.
The same image is used for all zoom levels, so if you zoom way in, the map will be very pixellated.
If the rectangle you drag is exactly the shape you get, so if you drag a very narrow rectangle down
one side, you will get a narrow triangle. We may try to modify this behavior at a later date, but
for now that is just the way it is.
- The fifty most recent earthquakes are shown in orange, except
the most recent earthquake which is shown in red.
Earthquake faults are also shown in red.

All email will be read, but, because of the volume of email,
we will not be able to respond to every email. Unfortunately,
we are unable to respond to requests for additional information about particular earthquakes. Look in our list of "Other Web sites of interest" below
for other sites that may have pertinent information.
If a particular earthquake you are interested in does not show up right away
at the USGS or Caltech sites, check in on those sites later.
Sometimes there are delays for those sites to post information. But
when info is posted there, it is much more accurate than the information
shown at this site.
