Precautionary measures that can be taken before and after a volcanic eruption

The most effective precautionary measure is to move far away from any active or dormant volcano, barring that, other precautionary measures for before a volcanic eruption is to constantly monitor the volcano for activity and to have an evacuation plan in place in case the volcano does erupt. During an eruption it all depends on what type of eruption it is. If it is a cinder cone, just staying away is good enough. If it is a lava floe, you can just walk away, most lava moves pretty slowly, do not ever walk on the lava, it may look solid but often has molten lava running beneath it. Stay away from where lava meets water, there can be explosions...

Advantages/Disadvantages of living next to a volcano

Disadvantages Sea - during a volcanic eruption earthquakes happen, and tsunamis may be created. Also, if it is a volcanic island, the island may be destroyed, and there is no escape. Lava flow - these are very slow moving, but destructive as they cannot be stopped and they set fire to everything in their path. Pyroclastic flow - these are impossible to outrun, travelling at about 300 km/h, and are extremely destructive Mudflow/lahar - these are mud rivers that have the consistency of cement, and destroy everything in their path, including buildings Advantages Sea - there tends to be abundant sea life near volcanic islands, so there will be lots...

Structure of a Volcano

A Volcano constitutes a vent, a pipe, a crater, and a cone. *The vent is an opening at the Earth's surface. *The pipe is a passageway in the volcano in which the magma rises through to the surface during an eruption. *The crater is a bowl-shaped depression at the top of the volcano where volcanic materials like, ash, lava, and other pyroclastic materials are released.  *Solidified lava, ashes, and cinder form the cone. Layers of lava, alternate with layers of ash to build the steep sided cone higher and high...

Formation of Volcanoes

Volcanoes form when hot material from below rises and leaks into the crust. This hot material, called magma, comes either from a melt of subducted crustal material, and which is light and buoyant after melting, or it may come from deeper in the interior of a planet and is light and buoyant because it is very hot. Magma, rising from lower reaches, gathers in a reservoir, in a weak portion of the overlying rock called the magma chamber. Eventually, but not always, the magma erupts onto the surface. Strong earthquakes accompany rising magma, and the volcanic cone may swell in appearance, just before an eruption, as illustrated in this picture....
