Compare And Contrast Landforms And Mauna Loa

Volcanoes. The naturally forming landforms that can look remarkably beautiful. Gentle slopes, or high rising heights with snow caps and greenery that seems to attract many tourists and sightseers around the world. These magnificent landforms can also cause major destruction and can produce forces that can explode, burn, and create a great deal of damage. Two of these extravagant wonders of the world is the Mount Saint Helens composite volcano in Washington, US, and the Mauna Loa shield volcano in Hawaii, US. These landforms have a eruption history of many colors. One has a great power in eruption, but another has a eruption that is quiet and gentle. In comparing these two volcanoes there are many likes, and dislikes, to consider. So the following…show more content…
Mauna Loa is the largest volcano in the world measuring 2,000 miles². Mauna Loa is 13,677 feet tall, 74 miles long, and 64 wide. On March 24, 1984, at 1:30 in the morning, Mauna Loa began to erupt. This eruption is known as a quiet eruption. The eruption does not cause the volcano to explode or make much of a loud noise. This is due to the basaltic lava and a low amount trapped gases. It just flows a low viscosity lava out of the volcano. When the eruption started, lava started pooling out of the top of Mauna Loa. Within 2-3 hours about 80% of the crater on top of the volcano was submerged in lava. Many worried that the lava would overflow and run to the Mauna Loa Observatory, but the eruption shifted to go northeast rift zone instead. This instead threatened the nearby city of Hilo, populating 40,000 people. The lava headed straight for the town. On the way, the lava reached a generator and left it destroyed. This took out the power for the observatory on the other side of the volcano. This lava that Mauna Loa erupted is a basaltic lava. Basaltic lava silica content is low and only contains 45-55% silica. This makes the magma more liquid and gives it the ability to move quickly. As the lava approaches the vulnerable city of Hilo, many of the people began evacuating. Luckily, the lava stopped at the outskirts of town, burying 16 miles of land owned by the state, never to be seen again. The…show more content…
These differences are in the makeup of the volcano, the impact on society, and the eruption itself. Mount Saint Helens, used to be a wonder of the world, but now a damage site of what happened on May 18, 1980. Mauna Loa is a tourist destination and one of the most active dispensers of lava and magma in the world. As shown, these volcanoes can’t be more different. Yet, each volcano has been a culprit to destruction, and have similarities within themselves. This report has expressed many similarities and differences and brought facts and knowledge to the historical eruptions by these impressive and ancient structures of
