San Andreas fault is cracking and it will cause floods on a record level
Показать описание
California, home to millions of people and numerous cities, sits atop a fault line that spans over 800 miles from Cape Mendocino to the Mexican border. The San Andreas fault has a long history of creating high-powered earthquakes, which is why it is closely monitored by the US government and all Californians alike. But now, a recent discovery in the San Andreas fault area has revealed that a section of the fault has undergone something called a seismic creep, which is when the plates move gradually, releasing stress without causing large quakes. But, as researchers looked back millions of years, they found evidence that this section of the fault may have experienced earthquakes of a magnitude of 7 or greater. That's stronger than the infamous Loma Prieta earthquake that shook the Bay Area in 1989.
But the question is!
When is the San Andreas fault going to crack?
Will California slide into the sea when it happens?
When massive and powerful earthquakes are discussed, the San Andreas fault automatically comes to mind, especially for those living in California. It is a significant fracture of the Earth's crust in extreme Western North America. This fault is divided into three segments: the northern segment from Hollister to the Mendocino Triple Junction, the central segment from Park field to Hollister, and the southern segment from Park field to the Salton Sea.
The San Andreas fault is greatly feared because of the tectonic movement detected around the foot as it's been associated with periodic earthquakes said to often develop near the surface along its path. When Geoscientists drilled into the earth's surface nearly 2 miles below as part of the SAFOD (San Andreas Fault Observatory at Depth) project, they discovered something incredible - a zone of the fault that has experienced not just one or two, but potentially more than 100 earthquakes!
A perfect example Americans aren’t going to forget so soon is the disastrous earthquake that happened in 1906. Another one occurred in 1989 but wasn't as severe as the first one. Five years later, a more powerful and destructive earthquake happened in the Los Angeles suburb of Northridge along one of San Andreas larger secondary faults. The fact that these earthquakes happened and affected cities does not mean the San Andreas fault went through the town.
But what type of fault is the San Andreas fault?
San Andreas fault would be classified as a strike-slip fault. This means the fault's two sides move horizontally past each other rather than vertically. It's this movement that creates the directivity pulse and allows energy to be transmitted down the fault. Many people believe that tectonic plates move at an incredible speed, but the reality is quite different. These plates move past each other at a sluggish pace of just a few inches per year - equivalent to the rate at which your fingernails grow. Despite this slow rate, plate movement is far from steady. In some years, the plates can be locked in place, pushing against one another with no motion. However, strain gradually builds up over time until the rock breaks along the fault, and the plates suddenly slip a few feet. This sends out waves in all directions. While the San Andreas fault runs underground, it is visible in some places #sanandreas #tsunami #flood #earthquake
