Constructive effects/Tales and Legends
By Ella Walley
What is the condition? Most recent eruption?
Result of a hot spot or subduction?
-produces pyroclastic flows= ground hugging
-dense clouds of black ash are called ash falls
-dark lava flows
-rocks that are erupted are called andsite, which are intermediate volcanic rocks, made up of 53-63%
Description of eruption
Effects of past eruptions on landscape, people, etc.
Any prevention ideas? What do experts predict for the future?
-Condition- Dormant= has erupted in modern times, but is inactive today.
-Most recent eruption- 1944
-Subduction= African plate is subducted under the Eurasian plate.
-79 AD eruption was responsible for the destruction of Pompeii and Herculaneum
-experienced 8 major eruptions over 17,000

Future- most likely won't erupt any time soon
because of the small magma supply
-if does erupt= very forceful eruption (philnean)
