Discovering Geology – Earth hazards

There are more than 1500 active volcanoes on Earth. Around 50-70 volcanoes erupt every year. There are 82 volcanoes in Europe, 32 of these are in Iceland, one of the UK’s closest ‘volcanic neighbours’. Most of the volcanoes on Earth are not well-monitored or even monitored at all. Some volcanoes erupt almost continuously (e.g. Etna and Stromboli) but some don’t erupt for tens, hundreds or even thousands of years.

Why does the BGS study volcanoes?

The BGS have a team of volcanologists that work on various research projects in locations around the world. This research helps governments and local people to:

  • understand the signals that may indicate an eruption will happen soon
  • understand different volcanoes personalities and behaviour
  • understand the potential hazard posed by volcanoes
  • work with communities living near volcanoes, and also further afield, to try and reduce risk from volcanic eruptions
  • understand how best to take advantage of volcanic systems; e.g. geothermal energy

The BGS volcanology team work with government agencies to provide support and scientific advice not only during volcanic unrest or ‘changes from a volcano’s normal state’, but also in preparation for potential future activity.

Understanding sinkholes and karst

Sinkholes are often saucer-shaped hollows that are the result of some kind of collapse, or removal, of an underlying layer of rocks that used to support the layer of material at the surface.
