Volcanoes – Mt . Saint Helens Mt . Rainier


No matter how much power humanity has accumulated , natural calamities are still stalking humans in many parts of the planet . The Washington State is no exception . One of the foremost potential sources of disaster is the two mountains located within the state bs – Mt . Saint Helens Mt . Rainier . These two giants have the explosive power possessed by all volcanoes , even if they are sleeping . Exploration of the challenge posed by these two natural objects is the way to prepare effectively for the possible calamity in [banner_entry_middle]

case it strikes unexpectedly

Mount Rainier

Mount Rainier was called the sleeping giant ‘ since it has not had an eruption for 150 years . This is not , however , such a long time from the geological point of view , and most scientists expect the mountain to come to life again some day . In the USGS survey , it comes up as the 3rd most dangerous mountain in the US because of its proximity to a large number of people

The disaster can happen not just because of a large-scale explosion . The top of Mt . Rainier is crowned with a larger accumulation of ice and snow that of any other of the Cascade volcanos and even all of them together Therefore , it would not take an explosive 1980-style St . Helens eruption to create a disaster for people downstream of Mount Rainier even if just part of the huge ice cap were to melt ( Mount Rainier The sleeping giant . There is also the danger that a portion of the mountain will break off from the crater if the mountain starts to heat up and will destroy communities in dangerous proximity to Mt . Rainier . A stream of lahar , or the mixture of mud and water can come down resulting in the flow thicker than the one that slid down the slope of Mt . St Helens in 1980

Surprising or not , evacuation danger signs posted on settlements do not prevent people from settling in the area that enjoys lower housing prices than in the surrounding pricey Puget Sound . As a result of thriving construction , roughly 30 ,000 Puyallup River Valley residents are in direct danger in a volcanic eruption , along with more than 100 ,000 people living in Mount Rainier ‘s six other valleys ( Mount Rainier : The sleeping giant . Despite the authorities ‘ strenuous efforts to integrate the latest scientific discoveries with evacuation plans , Puyallup remains their big public safety issue ( Mount Rainier : The sleeping giant

Mount Saint Helens

Mount St . Helens demonstrated its danger in 1980 when a massive eruption killed 57 people when it blew 1 ,300 feet off the volcano ‘s top devastating a vast landscape and spewing ash around the world (Paulson 2005 . Although from these days scientists moved forward with their predicting technology , one still remembers that 1980 was a failure for seismologists eager to avert the calamity

In 2004 , there was a red alert as there occurred a series of earthquakes and a steam rose over the mountain . The authorities… [banner_entry_footer]
