Key points

  • Before a volcano becomes active it gives off warning signs such as smaller earthquakes, a temperature rise around the volcano and the release of sulphurous gases.
  • There needs to be a detailed plan for dealing with eruption such as an exclusion zone around the volcano, an emergency supply of basic provisions and an evacuation plan.
  • It is not as easy to predict earthquakes, but there are some ways of monitoring the chances, such as laser beams to detect plate movement, a seismometer to pick up vibrations, and radon gas monitoring.
  • Earthquake proof buildings and bridges have been constructed in many major cities to absorb the earthquakes energy and withstand movement.
