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

Sea - there tends to be abundant sea life near volcanic islands, so there will be lots of seafood Fertile soils - The volcanic ash from eruptions is very fertile and good for farming Tourism - Volcanos are good for tourism, bringing towns lots of money Quarry - There are lots of stone deposits from volcanic eruptions, which can be converted into quarries. Geothermal energy - There will be natural vents near the volcano, in the ground which can be used to provide geothermal energy.

The advantages seem to outweigh the disadvantages, because wherever there is a volcano, people live around it because of the rich fertile soil, despite the threat of an eruption. Examples of this are Naples (Mount Vesuvius), and Fuji City (Mount Fuji)

Volcanoes dominate the landscape in Nicaragua and Costa Rica – big, massive volcanoes rising up out of nowhere. Occasionally, steam or glowing red lava seeps out of tops. How do volcanoes form, anyway? Most volcanoes are formed by the movement of tectonic plates on the surface of the earth. These plates are basically huge pieces of rock that ‘float’ on the mantle (a layer of the earth that is sort-of liquid rock). The tectonic plates are in constant motion, albeit very slow motion. They sometimes move toward each other, other times they’ll move apart, and still other times one will sink while the other rises above it. PLATE TECTONICSr!
