∙ 14y agoThey may infer that the volcano has become more active - an increase in seismicity (an increase in the number of earthquakes) may be caused by the movement of magma into a high level magma chamber near the earth's surface, causing an increase in the magma pressure which can cause fracturing of the surrounding rock mass.
This may be a warning sign of an impending volcanic eruption.

What will happen to the habitat immediately after a volcano eruption?
It wi be destroyed.
How could a family stay safe during a volcano eruption or an earthquake?
For a volcano eruption, the family can be safe because of the distance between them and the volcano whereas for an earthquake it may happen if the calamity's force is weak.
When did the earthquakes happen in the mount St. Helens eruption of 1980?
March 20, 1980 was the date of the big eruption.
What might happen if more magma is injected into the chamber from below?
A magma is injected into a volcano's plumbing the first thing you see is inflation of the land/volcano surface, this would be accompanied by earthquakes and low frequency harmonic sounds caused by the flow of magma through the volcano's passages (like a flute). There would then be the release of gasses from the vent (a phreatic eruption) as magma heats ground or surface water. This may then be followed by eruption of magma from the volcano's vent.
Why do earthquakes frequently preceede volcanic eruptions.?
Before a volcanic eruption can happen, magma has to migrate form depth into the volcano's magma chamber. This movement of magma inflates the ground round the volcano, and provided the energy to initiate earth movements which cause a swarm of earthquakes.
How can earthquakes be a warning sign that an eruption is about to happen?
The earthquake moves the ground and the movement makes a volcano erupt!
Why can earthquakes be warning signs that a volcanic eruption is about to happen?
A volcanic eruption is a violent event on a very large scale. When a volcano is about to erupt, the immeasurable subterranean forces that had previously been in some kind of equilibrium are now unbalanced. Great masses of material are shifting in reaction to the shift in force, and the shock waves register as earthquakes. Is a nearby volcano letting off steam an gas? Watch your seismograph and get a go bag ready. If the seismograph needle starts jumping, best get to the car and evacuate. Seismologists and volcanologists are always watching the seismographs in addition to making visual observations of the volcano. Earthquakes are common around any volcano that is about to erupt.
Do earthquakes happen while volcano erupts?
yes,they do.
What will happen to the habitat immediately after a volcano eruption?
It wi be destroyed.
Is a volcanic eruption likely to occur on the east coast of the US?
Is a Volcanio eruption likely to occur on the east coast Of the untial States
Are any natural disasters related?
Tsunamis are related to earthquakes in that earthquakes happen underwater, creating Tsunamis. Volcanoes are somewhat related to earthquakes in that some warning signs of volcanoes are tiny earthquakes, created by the movement of magma and the swelling of the volcano. Other than that, I don't think so.
Why can earthquakes be a warning that a eruption is about to happen?
Movement of high pressure magma underground typically occurs before a volcanic eruption. This magma is under such a high pressure that it can cause hydraulic fracturing of the surrounding rocks and even bulging of the crust. Both these events will release seismic waves (cause earthquakes). All these data help geologists predict that an eruption is about to occur.
How could a family stay safe during a volcano eruption or an earthquake?
For a volcano eruption, the family can be safe because of the distance between them and the volcano whereas for an earthquake it may happen if the calamity's force is weak.
How come volcanoes aren't that dangerous as earthquakes and tsunami?
That is because you can predict a volcano eruption before it reupts such as the animals behave differently or ash, lava, smoke, cinda and sand is seen on top of the volcano. There will be enough time to escape before it erupts. However, tsunamis and earthquakes occur suddenly anytime. We will never know when will it happen...

What two types of natural disaster happen in Mexico?
Earthquakes and volcano eruptions.
