Starter

Look back at your work from last lesson. Describe the spatial distribution of vulcanicity.

Magnitude and frequency

• Magnitude: Volcanic explosivity index (VEI) - a logarithmic scale running from 0 to 8
• Frequency: how often volcanoes erupt and
• Regularity: how consistent the gap between eruptions is.

TASK:
