If you live in or visit a volcanic area:

Prepare by examining the community’s emergency plan, if there is one, together with

your family. Contact the mayor’s office for details.

Monitoring

Fortunately, most of the time, monitoring helps us anticipate eruptions and prepare for evacuation.

Scientists have several types of monitoring and observation systems available.

Timescale

Eruptions can last a few hours to several years. Between erup-tions, volcanoes can remain quiet for several hundred of years.
