California Earthquakes: San Bernardino, San Diego, Los Angeles

USGS Earthquake Reports 4.5 San Bernardino Earthquake and 6.1 Costa Rico Earthquake

Maggie Ray
Californians returned to rock and roll state on Thursday night when a 4.5 San Bernardino earthquake was registered. The San Bernardino earthquake followed just hours behind a 6.1 Richter Costa Rico earthquake. As aftershocks continue to follow the Costa Rico earthquake, California residents in San Bernardino and Los Angeles checked for damages. USGS reports the San Bernardino earthquake was felt as far south as San Diego and as far north as Palmdale. No damages have been reported. SoO far no casualties have been reported in the Costa Rico earthquake.

A San Bernardino earthquake is certainly nothing new as the San Andreus fault runs at the base of the San Bernardino Mountains. Earthquakes rattled strong and deadly in 2008, killing more than 88,000 people world wide according to the US Geological Survey (USGS). This is the highest number of earthquake casualties since 2004 when the tsunami hit Asia. The strongest earthquakes in the US for 2008 were in Alaska's Aleutian Islands and while the USGS earthquake reporting indicated they measured at 6.6 the impact was low because of the low population.

California earthquakes have historically been some of the most deadly in the United Stated. According to the USGS, earthquakes in California account for 5 out of the top 10 deadliest US earthquakes. The most deadly California earthquake was in 1906 in San Francisco when about 3000 people died. The Northridge earthquake of 1994 claimed 60 lives.

The San Bernardino earthquake and the Costa Rico earthquake serve as reminders to the populations of California and Central America to remain prepared for earthquakes at all times. Recent California earthquake drills due media attention when more than 5 million residents took part in a drill scenario based on a 7.8 magnitude earthquake. The drill was a part of the Great Southern California Shake Out.

USGS Earthquake hazard service offers an online map which shows the latest earthquakes in the world for the past 7 days. The map can be viewed at http://earthquake.usgs.gov/eqcenter/recenteqsww/.

USGS Earthquake services provide a wealth of information to residents looking for status on recent earthquakes as well as historical information.

    why has'ent the city provided the city of san bernadino about the land that they live on. The whole city is in a trough and the city say's only that they want to make money. There is a residential community fifty feet away on both sides since the city deem's that to be the safe distance from a fault line and on both side's live residential communities with children. The fault line is visable you can jump across it and they decised it with a park wtf?

    Great reporting. It's good to know that Cali building have gotten good enough to handle that magnitude of earthquake. We had a 4.1 nearby in Wells, Nevada and it destoyed the town.
