There are many ways to predict when the volcanos is going to erupt. Well, when we predict, we want to know when the volcano is going to erupt, how destructive will that eruption be and many other measures. But before we predict, we need to know why is it that we want to know all those stuff that is going to happen in future. Well, the answer is sinple. so that people can be well prepared. And so that we can minimise the destructions that the lava and that ashes are going to cause.
In predicting an eruption of a volcano, we can use the
seismometer.
A seismometer (or seismograph) is a sensor that detects the intensity of earthquakes caused by magma that is moving. well, the seismometer does not actually 'predict' when the volcano is going to occur but it detect the intensity of earthquakes caused by the magma so we can roughly predict by ourselves when and how the eruption is going to be.
The
tiltmeter is a sensor that uses a laser beam to find the rising or lowering of magma levels by measuring changes in ground elevation. when the scientists finds out that the level of magma is moving upwards, it means, there is going to be an eruption very soon so it can warn people around it.
Scientists also take temperatures and gauge gas by using a
Landsat satellite. The satellite uses infared sensors to detect temperatures and changes in volcanoes. Aircraft monitors the amount of gas released from the ground. An increase in sulfur dioxide and other gases usually means that there could be volcanic eruptions.
Volcanologists use these instruments to successfully predict eruptions which saves many lives. Scientists are trying to develop new ways to predict future eruptions.
For normal people living around the volcano areas, there are many simply ways of predicting the volcanic eruption without using any scientific equipments.
One example is to look for plumes of smoke or clouds of gas on or around the volcano that aren't typically there. As magma flows into the chambers beneath a volcano and rises to the surface, it can cause different gases to be released, which geologists keep a close eye on for changes in quantity or composition.
Look out for any changes in seismic activity near the volcano. Many volcanoes continuously give off rumbles or tremors, but a sudden increase in the number or strength of these quakes can indicate impending eruption
