How do you know when a volcano is about to erupt?

Answer 1

Volcanoes erupt because of the plates under the Earth's Mantle crash into one another, which causes an earthquake, which also causes eruptions. Yes, it is possible to determine whether a volcano will erupt or not. It is notpossible, however to determine when to any degree of accuracy! There are many signs that, when interpreted correctly can make a convincing indication of a coming eruption. The people who study volcanos (Geologists & Siesmologists) have lots of ways of attempting to predict an eruption, however, the science is still in a "Best-guess" state, and any prediction can be proven wrong either way. This is why there is no "early warning" systems for volcanos. Animal behaviour patterns are increasingly monitored around active volcanos these days; it's been observed that many species have instinctive ways of knowing when an eruption will occur.

Answer 2

Fundamentally we are not able to predict eruptions. However we can detect when the ground area inflates and seismically detect the noise of the lava moving in the volcanoes Plumbing. These give us some indication that an eruption is imminent but not as to its scale or exactly when.

Answer 3

Predicting volcanic eruptions is very difficult and depends on a number of factors. Scientists look at gas emissions, small earthquakes, and ground deformation, all of which can be affected by the movement of magma. It is not an exact science as no two volcanoes are quite the same. A volcano may show signs of unrest then quite back down, or it may erupt with no discernible warning.

Answer 4

Scientists monitor changes in seismic activity, gas emissions, ground deformation, and temperature to predict volcanic eruptions. Sudden increases in these parameters may indicate an imminent eruption. Advanced warning systems are put in place to evacuate populations at risk.

Answer 5

it will get really hot. you will burn to death

Answer 6

Scientists haven't found a sure fire way to detect when exactly a volcano will erupt but one sign of such an occurance would be increased seismic activity around the volcano.

Answer 7

a volcano is about to erupt if there are puffs of ash or sulfer exsplosins, then BOOM

Answer 8

ground shaking,earthquake
