# Wakey Wakey (DD-375)

> A dormant volcano has not erupted in a long time but could again. It can reawaken when new magma rises into its plumbing, when gases build pressure in the chamber, or when tectonic movement opens fractures. Scientists watch for earthquakes, ground swelling and gas changes. Mount Pinatubo, quiet for about 500 years, erupted in 1991. The footage shows an erupting volcano.

## Quick facts

- **DD-375-F01**: Not erupting but not extinct. _(Write-up · Exhibit A (Dormant))_
- **DD-375-F02**: New magma can rise. _(Write-up · Exhibit B (Magma))_

## Write-up

A volcano quiet for centuries can still erupt. Fresh magma and rising gas pressure can reawaken it.

1. **Dormant**: Not erupting but not extinct.
2. **Magma**: New magma can rise.
3. **Gas**: Gas builds pressure.
4. **Monitoring**: Quakes and swelling are watched.
5. **Pinatubo**: Erupted in 1991 after centuries.

### Transcript

Did you know, dormant volcanoes, though seemingly inactive, can be reawakened by changes deep in the Earth's crust. When tectonic plates shift, it can create fractures or increase magma pressure beneath the surface, which could trigger volcanic activity. In some cases, new magma can rise through the existing volcanic pathways, renewing heat and pressure in previously dormant chambers. The buildup of gases within the magma is another critical factor. If pressure becomes too great, it can eventually force an eruption. Dormant volcanoes are closely monitored, as reactive complex and can occur with little depending on geological shifts and movements. NOW YOU KNOW!
