So what geological happenings have
occurred over the festive season? Well this story caught my eye…
- The Chaparrastique volcano in eastern El Salvador has erupted!
Volcanoes can go off as and when they choose and this one has been
looking quite restless for a while now. The volcano began spewing hot ash and
smoke into the air but no-one has been hurt and anyone living within a 3km
radius (shown below) of the volcano has been evacuated and moved to temporary shelters to
minimise the risk. In this part of the world though there are more than 20
volcanoes in close proximity, so an impending volcano eruption is truely old
news.
This volcano is a stratovolcano built up
by many layers of lava, tephra, pumice, and volcanic ash. This volcano and the
many others lie on the ‘Pacific Ring of Fire’ which is a very large area of
subducting tectonic plate. The region contains the most active volcanoes on Earth
which are capable of great explosive eruptions.
