What are the signs of a volcano erupting?
Small (minor) earthquakes roughly around 2 magnitude.

Small (minor) earthquakes roughly around 2 magnitude.
What do many small earthquakes near a volcano mean?
Increases in seismic activity around a volcano are typically caused by the movement of magma below the surface into a magma chamber. This causes increases in pressure which leads to fracturing to the rock mass around the magma chamber causing small earthquakes. If the pressure continues to build it would ultimately force the volcano to erupt. As such the small earthquakes are potentially a warning sign of an impending volcanic eruption.
Are earthquakes and volcanoes related?
Earthquakes can cause a volcano to erupt.
What triggers the small earthquakes the occur around a volcano before an eruption?
Increases in seismic activity around a volcano are typically caused by the movement of magma below the surface into a magma chamber. This causes increases in pressure which leads to fracturing to the rock mass around the magma chamber causing small earthquakes. If the pressure continues to build it would ultimately force the volcano to erupt.
Do earthquakes start volcano eruptions?
Yes. Earthquakes can start volcano eruptions. Most of the time they don't, but if you have an ACTIVE volcano in your area then yes they can. What is an active volcano? An active volcano is a volcano that hasn't died off. Just like the volcano in hawii, it's active as it constantly pours hot red lava into the ocean.
What were the warning signs of the paricutin volcano?
The Paricutin is an active volcano located in Mexico. It erupted for the first time in the year of 1943, and the first warning signs of this even were rumbling, thunder-like noises, clouds that overshadows the skies. Then there were small earthquakes that caused a fissure in the earth, which developed in the formation of a small volcano.
Can earthquakes cause a volcano to erupt?
yes
Is there any effect on volcanic eruption by earthquakes?
earthquakes pressurize the main magma chamber in a volcano by the earth crust. as a result the magma comes out of the volcano
When does the volcanoes eurpted?
After the volcano sends warnings,the volcano will erupt.=the main warnings:==increases in the land==increased seismic activity (small earthquakes)==increased production of volcanic gases like sulphur dioxide=
How close can a person get to an active volcano?
An active volcano is just a volcano that can erupt. You can go and walk on it, even stand on the edge of the crater to watch the lava.If a volcano getting closer and closer froman erutpion, you might encounter toxic gaz and small lava flows as well as earthquakes.
Do earthquakes happen while volcano erupts?
yes,they do.
