Question 18
Your Answer:
Describe the Mt. St. Helens eruption in detail. Concentrate on
those aspects of the eruption that are most impressive to you.
How does this eruption testify to the awesomeness of the earth
and the God who created it? Your answer must be at least one
paragraph in length.
Mt. Saint Helens erupted on May 18, 1980. It is one of the largest volcanic
explosions recorded in North America. It started in March of 1980 with a
series of earthquakes under the southwest corner of the mountain. On
the morning of the 18th of May 1980, A 5.1 Magnitude earthquake was
recorded underneath the mountain. Shortly after the earthquake about 15
seconds surpassed and the entire north slope started to slide down the
mountain. The movement of the north slope allowed the blast to travel
outwards instead of a vertical blast. The eruption lasted for over nine
hours and the vertical ash cloud still was able to reach over 24KM or
78,748 feet into the atmosphere. The landslide was moving around
80KM/HR or about 50MPH and cause an 820-foot tsunami at Spirit Lake.
Many homes, and bridges were destroyed and 57 people lost their lives to
the eruption.
The volcanic eruption of Mt. St. Helens in 1980 destroyed 390 square
Kilometers of natural habitat area which killed most of the animals and
vegetation. Much of the land was sterilized by hot pyroclastic ±ows
reaching well over 1292 degrees Fahrenheit. Many scientists opined that
was this area would take decades, if not centuries, to recover from the
damage. But to the surprise, within a year, plants began to grow, and
animals returned and lived there. This shows the true awesomeness of
God and that all thigs are possible through him.
