Why do some people live near volcanoes or in flood plains?

Today, many millions of people live close to volcanoes for this very reason. People live close to volcanoes because Geothermal energy can be harnessed by using the steam from underground which has been heated by the Earth's magma. ... Apart from the volcano itself, hot springs and geysers can also bring in the tourists.
