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

There was also a tidal surge which swept the coastal areas, destroying properties and killed some tourists. 2 years after the earthquake, more than 20,000 people were still living in temp housing- some tents, some in prefabricated huts.
Environmental effects - Oil refinery with 700,000 tonnes of oil was set on fire, polluted air, water + land. Damage to a waste treatment plant + a PVC factory which contaminated rivers and killed fish.

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.
