Give the 3 ways to mitigate tectonic hazards.

1)Early warning systems -networks of seismometers and lazers work together to moniter earths movements andareas of risk (few minutes/seconds before) -quick communication when shaking detected (sms/sirens) -useful as: people get under cover-stop delicate jobs(surgery)-shut of gas 2)Predicting and monitering volcanoes -scientists moniter tell-tale signs before through seismometers lasers, escaping gas and tiny quakes -monitered during eruptions - increase evacuation zone - track ashclouds for aircrafts - use gasmask for ash 3)Building design -buildings which dont collapse - less deaths, cheaper repairs -strengthen building and bridges -flexible pipelines prevents flooding and fires
