On May 18th, 1980, Mount Saint Helen, a volcano in Washington erupted majorly. The eruption is the most studied volcano eruption. Mt. St. Helen was known as one of the most prestige volcanoes in the Cascade Range before its eruption on May 18, 1980. The eruption made a big blast that destroyed the northern part of the volcano, crushing millions of the trees below the mountain.
During this stage, the volcano erupts small amounts of lava very infrequently, often several million years apart. Eventually, erosion breaks the volcano back down to sea level where it becomes an atoll (coral atoll stage). Because atolls are the growth of coral and marine organisms, when the Pacific Plate carries the atoll to waters too cold for these organisms to survive, they erode away into seamounts and
First, the effect on people was not all that great. People were killed by rocks that fell. This phase was called the plinian eruption, it lasted nearly a day. Some people were also killed by volcanic ash and gas. Second of all, according to History.com, the city was buried by all of the ash from the volcano, dust poured across the land like a flood.
On May the 18th 1980, Mt Saint Helens in Washington State, United States of America erupted covering surrounding areas in ash, mud, toxic gases and lava. Mt Saint Helens is one of many active volcanos in the Cascade Mountain Range that runs along the Pacific Coast of the United States of America, a part of the Pacific Ring of Fire, named due to the many active tectonic plates in the region. The blast devastated an area of 20 square km. Within 10km of the summit, were there had previously been dense forest, no trees remained, beyond this area all trees were blown down. A further 600km2 was covered in ash and debris.
Supervolcanoes are even more powerful than regular volcanoes. This explosion is so powerful that it will destroy most of the northern United States. It would also launch one thousand cubic kilometers (six hundred twenty one cubic miles) of ash into the sky. This is the equivalent of four
Bardarbunga is an example of a type of subglacial volcano as it is underneath the Vatnajokull glacier. This 2,300 feet deep caldera contains many fissures along which eruptions frequently occur. Bardarbunga erupts approximately twice every century with the last eruption having been in 1910 before the more recent eruption in 2014-2015. This subglacial volcano is known for producing the largest lava flow in the past 10,000 years. Bardarbunga is also known as being a composite volcano that produces effusive eruptions.
Tidal waves can likewise be created by submerged volcanic ejections. Volcanic emissions are another catastrophic event, and they are brought on by magma getting away from inside the earth. A blast happens, discharging the magma from a bound space, which is the reason there are frequently likewise gigantic amounts of gas and tidy discharged amid a volcanic emission. The magma goes up within the well of lava, and spills out over the encompassing territory as
00Earthquakes occur almost daily due to the fact that Costa Rica lies between two tectonic plates: the Carribean plate and the Coicos plate. These two plates push and shove each other causing small tremors throughout which can cause landslides,volcanic eruptions and once in a couple years, quakes with devastating results. The strongest earthquake recorded occurred in 1991 with a measure of 7.6 on the Richter scale. This earthquake left 4 dead and buildings as well as bridges and road were completely destroyed. If another Earthquake occurs, the coastal cities would be the most affected ones as they are closer to the plates.
This is important to understand so that we may respect the power and destruction of volcanoes. Powerful civilizations have fallen because of volcanic eruptions and the entire world can be impacted because of a single eruption. Volcanoes can erupt with more power then any human made bomb and can send an array of dangerous hazards down its slopes. It is ironic that mankind knows all of the risks that come with living by a volcano, not only because of scientific research but also because of past volcanic eruptions, and yet people continue to build houses near or next to volcanoes. Volcanoes offer a lot of benefits to society.
