Find the key to predict the volcanic eruption

Research indicates that the precise determination of how magma moves is the key to predicting volcanic eruptions.

He found the key to predicting volcanic eruptions

Recently, a team of researchers at the University of Liverpool (UK) has discovered a previously activated sign that predicts a volcano about to erupt.

This is believed to be the key to the scientific world to predict the situation, make timely preparations, avoid disasters occur.

Dr Janine Kavanagh, a volcanic researcher at the University of Liverpool, said: "With more than 600 million people around the world living near a volcano, the risk of eruption and disaster will be greater than ever. Understanding the signals, the activation of volcanic eruptions, we will be able to make efforts to forecast and minimize risks. "

In order to come to this conclusion, experts built volcanic models using a tank full of jellies. They inject colored water back to mimic the gradual increase of magma and then observe how they work. All of these processes are recorded by a high-speed camera and synchronous laser.

Experts found a surprising decrease when pressure increased, magma would run horizontally and vertically. That means, the pressure drop can cause magma to create many layers of floating foam. And then the "movie " started.

Professor Sandy Cruden - tectonic and geologist at Monash University in Australia said: "A drop of pressure can" drive "the release of dissolved gas, increasing the ability of magma to explode and erupt. The bottle of carbonated soft drink and then turn on the bottle cap. Pressure drop will create bubbles, increase the volume and eruption link ".

From here, experts can make some predictions about volcanic eruptions. However, the accuracy of these "predictions" depends on the availability of satellite data provided and how to decode that information . Determining exactly how the magma moves is the key to predicting volcanic eruptions.

The study is published in the journal Earth and Planetary Science Letters.
