An earthquake with a magnitude of 3.9 occurred about 4 miles north of Fontana. It struck at 1:22 a.m. Local time on March 9, 2008. An aftershock measuring 3.1 occurred about a minute later.
A quake of this size is not expected to cause damage or injuries. It was widely felt throughout the Inland Empire, Riverside and parts of Los Angeles and Orange counties.
Quakes in this area are not uncommon. A 4.4 in
January of 2005 was preceded by several smaller foreshocks.

Format Change
I have made an adjustment to the data as it is displayed on our map pages. The time and date for each quake will now be listed as local (west coast) time.
It will take some time for all the maps to be converted to the new time format. Most of our historical maps may continue to show the times as UTC time. Refer to the column heading to see which time format is used for that particular page.

A strong 6.0-magnitude earthquake struck a sparsely-populated region of northern Nevada on Thursday, damaging buildings and rupturing water and gas mains. Fortunately there were no serious injuries reported.
This quake occurred outside of our regular map coverage area. However, I have prepared a special report for this quake. You can view it by

The sequence of earthquakes coming out of Northern Baja is quite impressive and is not showing any signs of slowing down. It resembles an aftershock sequence you might see after a 6+ earthquake. But there was no 6+ earthquake. In fact, the quake which started this was only a 5.4.
The quake was originally posted as a 5.4 and later downgraded to a 5.1. There is still some debate over the true magnitude of this quake. It will take some time to determine the actual magnitude. It should be somewhere between 5.1 and 5.5.
As of the time of this report the 5.4 quake has been followed by at least 35 aftershocks with a magnitude of 3.0 or greater. Five have been greater than 4.0 and two have been 5.0 or greater. In total there have been over 200 aftershocks.
How does this compare with previous quakes in the area? Data from previous years shows that in
May of 2006 a 5.4 earthquake produced 16 aftershocks of 3.0 or greater. In
February of 2002 a 5.7 quake in the same area produced nearly fifty 3.0+ aftershocks.
The question that I'm sure everyone is asking is whether something bigger and more destructive is on the way. Nobody can say for sure. The 5.7 quake in 2002 was preceded by increased seismic activity which started in December of 2001.
It is always best to be prepared. Plan as if a stronger quake is on the way. Make sure you are prepared by having a supply of bottled water and non-perishable food. Always sleep with a pair of shoes and a flash light near your bed. Make sure there are no loose items or furniture that could fall and hurt someone.
It's a good idea to always be prepared. The mainshock is usually the largest and most destructive, and waiting until after the mainshock to get prepared is a bad idea.

The area between Vancouver Island and Queen Charlotte Islands off the west coast of British Columbia was the location of two quakes. The first, a 5.3, struck at 2:39 am Saturday morning and the second and much stronger 6.5 quake struck about 20 minutes later at 3:01 am.
To soon to know if there is any significant damage or injuries. The quake was about 75 KM (48 miles) off the southern tip of Kunghit Island, which is part of the Queen Charlotte Islands.
The quakes were about 155 KM (95 miles) north-northwest of Scott Islands, Just north of Vancouver Island. This location is about 575 miles NNW of Seattle Washington.
A 6.5 earthquake is not likely to produce any damaging tsunamis.
As I'm typing this, a second 6.5 quake has been reported in the same area. This new quake truck at 3:44 AM. I will update the maps later today, when more information becomes available.
