Tectonic hazards are comprised of earthquakes and volcanoes; they are named ‘tectonic hazards’ as it is ultimately the movement of tectonic plates that cause these events. These hazards have the potential to kill thousands and devastate the region it strikes. Although the main hazard causes destruction, events that follow can be equally, if not more, devastating, for example an earthquake can often trigger a tsunami. Many strategies have been put forward to try and minimise the impacts and save lives, some have proved successful however, fighting the forces of nature has proved to be a difficult task.
It’s not possible to prevent volcanic eruptions and earthquakes, however, careful management of these hazards can minimise the damage that they cause. Prediction is the key aspect, as this gives people the time to evacuate and make preparations for the event. As a volcano becomes active, it gives off numerous warning signs that are picked up by volcanologists; hundreds of small earthquakes are caused as magma rises through cracks in the earth’s crust, temperatures rise as activity increases and the volcano will start to release gases. The techniques available for predicting and monitoring volcanic activity are becoming increasingly accurate, and many volcanoes are constantly being monitored, such as Mount Etna. Anyone sharing a region with a volcano should have a detailed plan in preparation for an eruption, which could include having an emergency supply of basic provisions, being able and ready to evacuate residents and emergency funds available as the inactivity of a volcano can provide a false sense of security thus residents should always be prepared for an eruption.
Unlike earthquakes, positive effects can occur as a result of a volcanic eruption as well as negative. However, the devastating effects of a volcanic eruption usually outweigh the positive impacts. Mount St Helens is a volcano
