San Andreas Fault

What are some examples of supervolcanoes? Mount Toba is a supervolcano in Indonesia. This volcano spewed out 700 cubic miles of magma, equal in mass to 19 million empire state buildings. This eruption was so big that scientists found ash from Toba in an East African rift valley. A massive plume eruption took place right at the P-Tr boundary. A new plume burned through the crust in what we now know as Western Siberia to form the "Siberian Traps," gigantic flood basalts that cover 2.5 million sq km

1906 San Francisco Earthquake was in the outermost shell of earth consisting of rigid plates that have been moving for hundreds of millions of years. Two of these moving plates meet in western California; the boundary between them is a zone of faults, the principal one being the San Andreas fault. The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault

historic earthquake epicenters but also a detailed map of every single fault line. Not until the deadly Long Beach earthquake of 1933 did politicians and engineers feel the need to start earthquake proofing the structures around them (Mualchin 2011). With the passing of the Field Act school buildings in particular were constructed with earthquake safety in mind. But the Field Act only covered schools. It wasn't until the San Fernando earthquake of 1971 where major infrastructure and hospitals were

or family homes to shower or get water in any way. Another reason why we should include laws is people can’t sell their homes by cause of there bring absolutely no water in their city. “Groundwater pumping could also put more stress on the San Andreas Fault” (Source 3). From my point of view, we do need laws

San Francisco is a mountainous city in northern California with a population of approximately 805,000 people, who are under the constant threat of tectonic natural disasters [1]. An estimated 10,000 earthquakes, holding a magnitude of 1.5 or above occur annually in California, with 387 of them centered in the northern region of San Francisco [2]. The Californian earthquake of April 18, 1906 was one of the deadliest natural disasters of all time, carrying an estimated moment magnitude of 7.8 and an

outpatient care to thousands of clients in 21 states. In San Francisco, where the healthcare provider is headquartered, the question of a large earthquake hitting the area is not if, but when. In the past, the area has experienced numerous catastrophic earthquakes. In 1906, an earthquake with an estimated magnitude 7.8, which occurred as a result of a rupture of 296 miles of the San Andreas fault (USGS and UC Berkeley, n. D), struck the greater San Francisco area causing wide spread damage and igniting

Geological history and hazards in San Diego The formation of San Diego region involved numerous activities which varied from volcano activities, the formation of Gulf, uplifting and tilting among others. These activities happened in a long span of time creating three distinct geomorphic regions: the west of peninsular rangers, peninsular ranges region, and the Salton Trough region. The geomorphic division reflects the basic difference amid geographic parts containing Mesozoic metavolcanic, metasedimentary

One of the main lessons is that the tectonic forces are still highly active. This is because the quake happened near the fault lines of the Pacific and the North American plate. It shows that scientists are actually right in their findings that state that the world is ever changing. Another example of the lessons learned from the earthquake is the fact that the Earth is a

release of energy in the Earths crust. There are various ways this energy is released. Manmade explosions, dislocation of segments of the crust or volcanic eruptions are all triggers for an Earthquake; however, most are caused by a slippage of faults. A fault is a fracture in the Earths crust along which two blocks of the crust have slipped within one another.

1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future. The 1906 San Francisco Earthquake tectonic setting was in the outermost shell of earth known as the crust this is composed of rigid plates that have been moving for hundreds of millions of years. Two of these moving plates meet in western California; the boundary between them is a zone of faults, the
