A volcanic eruptions are devastating events that cause mass destruction throughout our society. Volcanoes are made by lava and ash coming out of the ground and hardening. Then over time, it will create a volcano. Volcanoes kill 540 people each year(Fox News). Volcanoes can be caused by other natural disasters or pressure underneath earths surface but the destruction can be minimized by following the evacuation route.

To begin with, volcano eruptions can be caused by many different things. One way a volcano erupts is when it is located on a boundary line of tectonic plates. In the text, Why Do Volcanoes Erupt it notes When one plate pushes under the other, this forces molten rock, sediment and seawater down into the magma chamber. The rock gets melted to magma, and eventually overfill the chamber until it erupts. Another way the volcano can erupt is when there is a decrease in external pressure in the chamber. An article states A decrease in external pressure on the magma chamber may also allow for an eruption by minimising its ability to hold back increasing pressures from the inside(Why Do Volcanoes Erupt). Usually a natural disaster like typhoon will cause a huge decrease in external pressure in the volcano. Volcanoes also have a huge effect on climate change as well. For example, Mount Tambora's eruption was so big that it put a lot of particles in the air causing it to block the sun so the temperature dipped down. This caused many crops in that area to die. All in all, volcanoes have many ways that they can erupt which can cause major effects in the climate.

There has been many catastrophic volcanic eruptions that has caused mass destruction to our society. Two examples of volcano eruptions are Mount Tambora and Mount st. Helens. Mount Tambora erupted in 1815 at sumbawa, an island in Indonesia. An article notes that The death toll is probably about a million people(Little). That is more than a whole city filled with people. Another huge volcano is Mount st. Helens. This volcano erupted in washington on march 7, 1980. This terrible event killed 57 people and the ash went all the way to Minnesota. The eruption was caused by seismic activity in the state. The text states 4.2 magnitude tremor was recorded four days after the seismic activity(History.com Editors). To prevent any more destruction, many residents evacuated the area and the national guard put up road blocks to prevent people from going into that area. These are only two of the many big volcanic eruptions that can cause a lot of damage if not careful.

One of the most recent volcano eruptions was the volcano in Kilauea, one of the islands in Hawaii. It started in 1983 and has destroyed 35 structors. A website states The good new is that,so far, no fatalities or serious injuries have been reported by this eruption(Whitefield). To make sure there are no deaths, islanders are evacuating. The text states an eruption from Hawaii's Kilauea volcano forced more than a thousand island residents to evacuate their homes(Mexican volcanoes and how volcanoes are formed). All in all, this volcano eruption was a lot smaller than Mount Tambora and Mount st. Helens because of the death toll and other features of a volcano. This volcano is one of the most recent eruptions on this planet.

Finally, there are some safety tips to avoiding an injury during a fierce volcano eruption. In the text, it states Do not drive in heavy ash fall(Volcanoes). Ash is really dense so a certain amount of it can cause your car to cave in which would end up being a terrible car ride. Also, that ash can be really dangerous once it gets into the lungs. The text Volcanoes states Follow evacuation or shelter orders. If advised to evacuate, do so early. This could prevent from having to drive in the ash at all. These are some safety tips to how to survive a volcano eruption.

Volcanoes can be very beautiful but at the same time, they can have the ability to destroy a whole city. Imagine if a volcano just erupted. What safety precautions would be taken place? Would you evacuate the area or try to wait it out? But if volcanoes could be predicted, then it would allow everyone in the area to evacuate a couple days before the eruption begins. This would prevent any fatalilties or any extra damage that could be taken if not evacuating. Volcanoes have way more to them than what meets the eye.
