Chapter 2 - Preparation for an Eruption

Predicting eruptions

 

When a volcano becomes active, it displays a number of warning signs. It is difficult for you to pick up the warning signs. Volcanologists collect the data and verify that a volcano is ready to erupt. They have advanced gear that makes it easy for them to predict a near eruption date. Nonetheless, there are some warning signs that you can keep in mind. If you live near a volcano, you may experience minute earthquakes. They constantly occur as the magma rises slowly towards the Earths crust.

 

Volcanologists use seismometers, thermal imaging technologies, and gas samples to confirm eruption. For example, they use the thermal imaging technology with the help of a satellite to monitor the temperatures around a volcano. Such actions help them issue an early warning. Additionally, the advancement in the technology is helping volcanologists to predict accurate eruption date. The early warning system gives enough time for people living in the surrounding areas of the volcano.
