DISASTER!

People have been interested in disasters. We are excited and frightened by them. There are many kinds of disasters in the world and some of them were not predictable several years ago, but now computers and many scientific machines can help to give warnings of possible disasters.
A volcano is one of disasters. If erupting, it will blow the cloud of ash in a large area. Sometimes mountains carry away lava. It is dangerous so people are in the panic if lava flows near residential areas. We often classify lava into three types and they are hard one, watery soft one, and those of middle hardness. Hard lava tends to comes out from a global mountain, and watery soft lava tends to come out from a flat mountain, and lava of middle hardness tends to comes out from a mountain of middle height. Therefore we can predict what kinds of lava come out to check the form of the mountain.
A flood is also one of disasters. If a flood happens, many inhabitants die of swallowed in a muddy stream. An infectious disease also causes death because people have to spend in a dirty state for days.
Disasters are very dangerous and they kill many people every year. All we can do is escaping. Even if predicting, we can never control them.
