Seismologist with the United States Geological Survey are usually the first to arrive in volcanic areas, to predict volcanoes eruptions and to alert people so they can get evacuated safely. One problem with the predictions is that the size and direction can’t be predicted. With the new technology and equipment, it's becoming 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 States military bases are located near Mt Pinatubo from 10 to 25 miles away. They are trying …show more content…
There are four levels that the volcanologist use which are Level One: Activity Detected (Eruption not Imminent), Level Two: Activity more intense(Eruption probable), Level Three: Eruption likely within two weeks, and Level Four: Eruption within 24 hours. They alerted the population near the volcano with a level two and about 20,000 Filipino families moved to a safer area. The Clark military bases was nearby and had millions of dollars of equipment, planes, pets, hospitals that could get destroyed and with a population of about 14,500 people. The Volcanologists goal was not to underestimate or overestimate the possibility of an eruptions but to accurately predict the volcanoes. They flew over the Mt Pinatubo to check out the visible magma and dust. The volcanic activity was very frequently increasing at massive rates then subsiding. 120,000 people, 12 miles from the mountain is evacuated and a level 4 is alerted. The Clark military based was postponing the evacuation for a couple of
