Typical Eruption: (type your description below) – you may include an eruption map with citation (URL)
This volcano has been flowing for 150,000 years creating the volcano, and when it erupted it creates land slides and lahars because of its mud and lake inside off the volcano. It has a high silica content meaning a high viscosity, so the lava doesn’t move fast, creating the dome shape, if we replaced the land that had slipped off from the last eruption. This has also been steaming for a long time, the steam is highly toxic, and if you were to stick your hand in it would instantly burn off. Some other types of typical explosions are just flowing lava normally low-silica magma that will run freely, having a low viscosity, and will cover a big stretch of land, or as big as it can get, and will be very rounded, and sometimes steeper on 1 side then the other depending on the normal land flow. Luckily for the local people this volcano is 50 km off the coast otherwise it could do some sever damage to the every day life of those people in the surrounding area.

Hazards: (type your description below)
My volcano is 48 km off the shore of New Zealand, and is uninhabited. So the only precaution that would or should be made is to keep the boat at a safe distance from the volcano. Or, to prepare for a tsunami caused by the land slide. If there were to be a native tribe on this volcano and no way of telling when it will erupt, then they would most likely not make it off alive, for the last time it exploded it created a lahar that killed 11 unexpecting men. However if the we directly on the ocean they could easily make there way on boats and leave the village until it has ended and they have been told it is safe to go back. If this volcano was to erupt, depending on how high the explosion was, it could stay within the caldera, but it could just flow out the side of the caldera lowest to the ocean level. Some of the hazards of volcano’s are the amount of ash that falls, effecting animals and plants alike, Lahars, creating massive land slides, Volcanic bombs that could land farther than the actual lava goes and kill whatever it touches, the pyroclastic flows, which could come out of any vent in the volcano and you may not know it to be even there.

Typical Eruption: (type your description below) – you may include an eruption map with citation (URL)
The Typical eruption for mount Tambora doesn’t happen very often, the last eruption happened in 1967 and it was a 0 on the VEI test, which means there were no hazards for this eruption. A typical eruption is a huge explosion, with a heavy ash flow in the air it ruins crops and water sources.

Hazards: (type your description below)
Ash flow is one of the major problems, but in 1815 90% of the deaths from the eruption was from famine not the initial eruption. All of the crops were destroyed for many miles and nobody had enough water.
