Volcanic eruptions pose a threat to people’s lives and properties. In fact, volcanoes have great possible in causing some of the most intimidating and destructive disasters on the surface of the earth. The occurrence of active volcanoes appear when tectonic plates located under ground are in the slow and long process of collision. Before volcano erupts, there are warning signs that volcanoes display. These signs are closely monitored by scientist in order to predict the timing and seriousness of eruptions. As a supervene of volcanic eruptions, some mountain ranges and landscapes were formed.
In the United States, there are some active volcanoes located at Aleutian Islands, the Alaska Peninsula, Cascade Range of the Pacific Northwest, and Hawaiian Islands. Two of the renowned volcanoes in the Us are as follows:
Considered as the Hawaiian Islands’ youngest volcano, Kilauea Volcano first erupted on January 3, 1983. It was named “Kilauea” which means “much spreading” because of the volcano’s tendency to spew when it erupted. During Kilauea’s eruption, its lava is recorded to spread as far as 75 square kilometers, affecting grassland and forest and destroying 179 homes, and killing many people.
This volcano is regarded as one of the largest active volcanoes in the world. Its height reaches more than 29,527 feet or 9,000 meters and even taller as compared to Mt. Everest. It has recorded a total eruption of 15 since 1900. Its eruption lasted from less than one day to around 145 days. The last recorded eruption of Mauna Loa was on March 25, 1984 and lasted for a period of three weeks.
