Alton Horsfall and Nick Wright found a way to use silicon carbide in the creation of electronic components. They have developed sensors that can work in environments up to 600 degrees Celsius, or more than 1,100 degrees Fahrenheit.The sensors can be lowered into the mouth of a volcano where they will pick up changes in emerging gases. Changes in the composition of the gas mix can portend an eruption.

What actions can be taken to prepare for a volcanic eruption?

During a Volcanic Eruption

Follow the evacuation order issued by authorities and evacuate immediately from the volcano area to avoid flying debris, hot gases, lateral blast and lava flow.

Be aware of mudflows. ...

Avoid river valleys and low-lying areas.

Volcanoes can also have long-term effects on the climate, making the world cooler. Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes.

The Volcanic Explosivity Index (VEI). Volcanic eruptions vary in size and explosiveness. Volcanologists take a number of factors into account when they determine the “bigness” of a volcanic eruption.

earthquakes can be very dangerous if you were in the wrong place.They can make buildings fall down and set off landslides, as well as having many other deadly effects. An earthquake that occurs at the bottom of the sea can push water upwards and create massive waves called tsunamis.

The richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. ... For all other earthquakes, the moment magnitude scale is a more accurate measure of the earthquake size.

volcanoes are formed when Magma from in the earth's upper mantle works its way to the surface. At the surface,it erupts to form lava flows and ash deposits. As the time the volcano erupts and lava flows to the surface so it gets bigger and bigger.
