Seismometer

December 26th, 2004 marks the day a 9.1-9.3 magnitude earthquake triggered arguably the deadliest tsunami of the twenty-first century. The 1,300 km fault zone spawned a wave reaching fifty meters in height and five meters inland. Fourteen countries worldwide lost an estimated 230,000 people [Geist et al., 2015] and a devastating ten billion dollars to the colossal Indian Ocean swell. The devastation kick started efforts to create better technology and innovations so that when the next disaster…

According to USC Viterbi “School of Engineering…

easier to predict volcano eruptions correctly. In 1991 Mount Pinatubo in the Philippines erupted causing many tribes to evacuate their homes. Researchers from the Philippines decided to study Mount Pinatubo with the help of the United States. A seismometer is placed near the mountain and within two days it records about 400 earthquakes underground. Around the world about 50 volcanic eruptions occur a year but only a small amount of them are investigated. About 10 million people and two United…

earthquakes always hit some areas while others have never experienced even the slightest of the earth tremors. The process of measuring the type, size and frequency of earthquakes in a given area is vital to identify the seismic activity of the area. Seismometers are the instruments used to measure earthquakes that occur in various parts of the…

1 Camila Rejalaga Sept 24,2017 Earth 101 Volcano Project 2. What we learned from Mount Saint Helens: Surprises and New Science from the Eruption (Brochure) Welcome to Mt. Saint Helens Park Visitor Center! To better understand Mt. Saint Helens we must first go back to 1980. Although some of you might not have been born yet it was in that year that the US experienced its most destructive volcanic eruption in its history. Most of you might have already guessed it but it happened right here…

Apollo 13 was the seventh manned mission in the American Apollo space program and the third intended to land on the Moon. The craft was launched on April 11, 1970, at 13:13 CST from the Kennedy Space Center, Florida, but the lunar landing was aborted after an oxygen tank exploded two days later, crippling the Service Module(SM) upon which the Command Module (CM) depended. Despite great hardship caused by limited power, loss of cabin heat, shortage of potable water, and the critical need to…

oil underground. This is usually done with the help of a geologist who is usually employed directly by the firm. Some of the tools that the geologist might use to help them with this job include satellite images, gravity meters, hydrophones and seismometers. Before they begin to drill they must obtain a permission from the owner of the onshore or offshore land and conduct mandatory geological and geophysical surveys. There is uncertainty within these surveys so the only way to be sure that the…

earthquake. In fact, many were not built to regulation at all as the government did not have the resources to enforce building regulations. Given the area’s lack of frequent earthquakes there were no warning systems in place, and there was only one seismometer in the entire country. The lack of warning or preparation for this catastrophe greatly increased its impact and worsened the long-term…

Mount St. Helen's is an active stratovolcano in the Cascade Range in Skamania County, Washington and is part of the Ring of Fire centered around the Pacific Ocean. Mount St. Helen's was created when the oceanic Jean de Fuca plate subducted beneath the North American Plate and has a long history of eruptive periods followed lengthy dormancies. Her volcanic activity was marked by thousands of years of lava and pyroclastic flows only to fall silent and then reawaken to begin her destructive cycle…

Sidebar: The largest tsunami wave ever recorded happened in 1958. An earthquake triggered a massive rockslide on the shore of Lituya Bay in southeast Alaska. Almost forty million tons of rocks splashed into bay. The sudden impact generated a tsunami that crashed against the other shoreline, flooding the area. The local tsunami traveled down the length of the bay and into the Gulf of Alaska, taking millions of trees as it blasted through the water. The wave reached a run-up height of 1,720 feet.…
