line is the boundary between the Pacific Plate and the North American Plate. These tectonic plates slide past each other breaking rock, creating shaking and seismic waves in every direction. This shaking is what we know as earthquakes and the seismic waves are how they are rated based on severity. The L.A. area is located where slip rate of the plates is well known. The slip rates of the San Andreas Fault is calculated by its size and the rate that one plate moves compared to the other. The soft soil

space aren’t the only challenges scientists face when trying to obtain measurement data. Earthquakes are a dangerous phenomenon caused by the shifting of Earth’s tectonic plates along its fault lines. Fault lines are many kilometers below the surface of the earth making any direct measurement methods extremely difficult. When the tectonic plates shift to cause an earthquake, energy is released and radiates out from the fault line similar to ripples in a pond. These energy

size of the magnitude despite the area has had a long history of tectonic activity · There were between 64 and 104 major aftershocks, ranging in magnitude from 4.0 to 6.1, within 72 hours of the main quake. Causes: The earthquake occurred along the Longmenshan fault after a northeast striking thrust. The Longmenshan Fault which sits on the Indo-Australian Plate and the Eurasian Plate was ruptured by the quake. · The two plates collided and caused this giant earthquake. About 1.5 km of surface

Subduction and plate convergence off the coast of western North America can also be seen in the Mesozoic Era causing large lateral transport and contrast of the volcanic and sedimentary topographies. The Nevadan orogeny produced mountains such as the great North American Cordillera. This mountain building was also accompanied by immense erosion, a pause in tectonic activity, and the probable beginning of cave development. The Cenozoic Era showed unrelenting intense erosion and slower tectonic activity

Tectonic Hazards: Earthquakes Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other. The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that's built up. When

moving around, sliding past one another and bumping into each other. We call these puzzle pieces tectonic plates, and the edges of the plates are called the plate boundaries. The plate boundaries are made up of many faults, and most of the earthquakes around the world occur on these faults. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. Finally, when the plate has moved far enough, the edges unstick on one of the faults and there is an earthquake. Why

Earth Day, Then and Now Thirty Years ago, 20 million Americans participated in the first Earth Day on April 22, 1970. Fifth Avenue in New York City was closed to automobiles as 100,000 people joined in concerts, lectures, and street theater. More than 2,000 colleges and universities across America paused their anti-war protests to rally instead against pollution and population growth. Even Congress recessed, acknowledging that the environment was now on a political par with motherhood. Since that
