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.

Can earthquakes happen in Thailand?
Earthquakes happen everyday everywhere so yes thialand often has earth quakes.
How many earthquakes will happen in the next month?
55 earthquakes happen in the world. small ones though.
Do earthquakes happen in Romania?
Yes, Romania is subjected to earthquakes.
What Stages that lead up to volcanic eruption?
Fire,Ash,smoke clouds, and earthquakes
Did Mauna Loa's last eruption cause earthquakes floods mudslides etc?
there was and earthquake
What are the warning sign of eruption?
changes in the ground, climate changes, patterns of earthquakes, and animals behavior.
When did the earthquakes happen in the mount St. Helens eruption of 1980?
March 20, 1980 was the date of the big eruption.
Why can earthquakes be a warning sign that a volcano eruption is going to happen?
you guy are dumb
Why can earthquakes be a warning that a volcano is about to arupt?
Earthquakes can be a warning sign of an impending volcanic eruption because the movement of magma beneath the Earth's surface can cause the surrounding rocks to fracture, leading to seismic activity. This seismic activity can indicate the movement and pressure of magma within the volcano, suggesting that an eruption may be imminent.
Is there any kind of early warning of volcanic eruption?
Yes, there is early warning before most volcanic eruptions. The primary sign is small earthquakes or land tremors and shakes near the volcano.
How can earthquakes be a warning sign that an eruption is about to happen?
Earthquakes can indicate that magma is moving beneath the surface, potentially leading to an eruption. As magma rises towards the surface, it can cause the surrounding rock to crack and shift, resulting in seismic activity. Monitoring earthquake patterns along with other volcanic indicators can help scientists predict and prepare for potential eruptions.
Were there any earthquakes before the eyjafjallajokull eruption?
Yes, there were several earthquakes leading up to the Eyjafjallajökull eruption in 2010. These earthquakes were caused by the movement of magma beneath the volcano, which eventually led to the eruption.
What happens to the number and intensity or small earthquakes just before an eruption?
Before a volcanic eruption, there is often an increase in the number and intensity of small earthquakes, a phenomenon known as volcanic seismicity. This occurs as magma rises towards the surface, causing pressure to build up and fractures to form in the surrounding rock. The increased seismic activity can serve as a warning sign of an impending eruption, indicating that the volcano is becoming more active. Monitoring these earthquakes helps volcanologists assess the likelihood and timing of an eruption.
What are safer volcanoes or earthquakes?
Volcanoes are safer because they have warning signs and people can get away quicker and happen less often
What time does tsunami usually occur?
Tsunamis can occur at any time of day or night, but they are more likely to happen following an earthquake or underwater volcanic eruption. Tsunamis are most common in the Pacific Ocean's "Ring of Fire." It is important to have an early warning system in place to mitigate the impact of a tsunami.
What can give a warning for earthquakes about one tenth of the time?
If you take the past earthquakes and study them and how they were you can find out about where some future earthquakes might be then you can provide a warning for earthquakes about 10% of the time.
Was there a warning that the eruption was about to happen for eyjafjallajokull?
Yes, there were several warnings prior to the eruption of Eyjafjallajökull in April 2010. Increased seismic activity, including hundreds of small earthquakes, was detected in the weeks leading up to the eruption, indicating that magma was moving beneath the surface. Additionally, researchers noted changes in the geothermal activity and the melting of glaciers, which hinted at an impending volcanic event. These signs allowed scientists to anticipate the eruption and issue alerts, although the scale of the subsequent ash cloud was still surprising.
