It’s not a fault line, but a networkįault lines occur where rocks on two sides push against or slide past each other, displacing the earth’s crust. Here’s what you need to know about that massive fault zone and what it means for future California quakes. In light of this week’s quakes, USGS researchers are reiterating their prediction that there’s a 70% chance an earthquake of a magnitude of 6.7 or higher will strike the San Francisco Bay area along the San Andreas fault zone before 2030. Those earthquakes occurred along a fault centered near Ridgecrest, California, but it reminded geologists of the looming danger of another major quake along the imposing San Andreas fault zone to the west, which could cause significantly more damage. The United States Geological Survey (USGS) warned that another earthquake of a similar magnitude could strike within the next week, while aftershocks have occurred an average of once a minute since Friday night. Residents of Southern California are on high alert after a 7.1-magnitude earthquake rocked communities near the Mojave Desert on Friday, just one day after a 6.4-magnitude quake occurred in the same area. Seismic activity along the San Andreas fault line could trigger a devastating earthquake in California by 2030:

Learning how to shut off gas, water and electricity in case the lines are damaged.

Strapping TVs, computers and other heavy equipment to prevent tipping.

Fastening shelves to wall studs and securing cabinet doors with latches.

Strapping water heaters and large appliances to wall studs.

How can you prevent property damage? The Illinois Emergency Management Agency has a few tips for you: A scientist tells them that the likelihood of an earthquake on the New Madrid fault of a 6.0 during the same timeline is around 40-50 percent. WLOX-TV reports that the risk of another earthquake on the New Madrid fault of the same size is 7 – 10 percent over the next 50 years. It was felt up the eastern seaboard into New York City, Philadelphia, even up to Canada. In 1811-1812 the area in southern Missouri was hit by an earthquake that registered 7.5 on the Richter scale. The New Madrid fault zone is very active. Illinois is flanked on its western and eastern borders by two active seismic zones: the New Madrid Seismic Zone and the Wabash Valley Seismic Zone. They say that the 7.0 magnitude quake that shook California would have a devastating impact on the state. The Illinois Emergency Management Agency is asking people to be prepared for earthquakes. Larger earthquakes are represented by larger circles.

Green circles denote earthquakes that occurred prior to 1974 (USGS Professional Paper 1527). Red circles indicate earthquakes that occurred from 1974 to 2002 with magnitudes larger than 2.5 located using modern instruments (University of Memphis).
