[2015] Erik Newman: Mt. Rainier

Mount Rainier

Mount Rainier is a volcano located in Washington, USA. Its coordinates are 46.8529 degrees North and 121.7604 degrees West. It is along the ring of fire, which makes it very deadly to its surroundings. This volcano is VERY active, and is on the watchlist.

The mountain we call Mount Rainier was once called Talol by the first native Americans in the area. The name Talol means "Mother of waters". The natives who named this this mountain were the Puyallup people, who spoke Lushootseed language.

Mount Rainier has erupted, but the last eruption was in the 19th century, about 150 years ago. Before it erupted then, it had erupted a few times, all being in the 1800s. If Mount Rainier erupted today, it might take out the city of Seattle.

Mount Rainier is a very big and old volcano. It is a giant 4,392 meters (14,411 feet) and is about 500,000 years old. Mt. Rainiers compositon is Andesite to DAcite. The reason it is so big is because it's a stratovolcano. Stratovolcanoes are cone shaped volcanoes conducted of one layer of hardened lava, tephra, and volcanic ash. Another name people call the stratovolcano is the "Super volcano".

Mt. Rainier is in the Juan de Fuca plate. The Juan de Fuca plate is in the western part of Washington state. The type of plate boundary is a divergent boundary. A divergent boundary is when magma pushes against Earths crust, splitting it.

Some good things about volcanoes is that they can sometimes produce new land and create good minerals for the Earth. A lot of the times, volcanoes destroy and kill innocent people. If a scientist is saying that a volcano is going to erupt in a matter of days, you should try to evacuate as soon as possible.
