Why people live in places with volcanic activity:
Economic: Volcanic soils v. fertile e.g- worlds best coffee grown in Columbia on volcanic soils. Minerals such as tin, silver, gold, Cu and diamonds can be found in volcanic rocks so money outweighs the risks. Volcanoes provide cheap geothermal ener

predicting + preventing volcanic eruptions
Hot springs are measured, tunnels in volcanoes with seismometers, aircraft used to measure amount of gas being given off, tiltmeters detect when volcano swells up as it fills with magma.
