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.

Is Krakatoa a oceanic volcano?
Well after the eruption 1883 eruption Krakatoa was an Oceanic volcano, (around 1889) until it grew and regained it's height. It is now a land volcano.
What happened before mount st helens eruption?
Before the eruption of Mount St. Helens in 1980, there were several smaller explosive eruptions and earthquakes that signaled the volcano's increased activity. The eruption on May 18th, 1980, was preceded by a series of steam explosions, a bulge forming on the north flank, and increased seismic activity. Scientists closely monitored the situation and warned of the impending eruption, leading to the evacuation of the area around the volcano.
What is the name of the Martinique volcano with a violent 1902 eruption?
The name of the Martinique volcano with a violent 1902 eruption is Mount Pelée. Its eruption in 1902 devastated the city of Saint-Pierre, killing around 30,000 people.
What was the amount of materials expelled on mayon volcano eruption?
Around 60 million cubic meters of volcanic material were expelled during Mayon volcano's 2018 eruption. This eruption resulted in ashfall, pyroclastic flows, and lahars.
What does the area around a volcano look like prior to beginning to erupt?
Before a volcano erupts, the area around it may experience increased seismic activity, such as earthquakes, gas emissions, and ground deformation. The volcano may also show signs like steam or ash emissions, increased temperatures, and changes in the volcano's shape. These precursory signs can signal the potential for an eruption.
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.
Are there signs for the eruption of volcanoes?
Before a volcano erupts, there is normally an increase in earthquakes, you might see some volcanic ash come out, you might see an increase in gas or steam around the volcano, and you might see a change in height or shape of the land around the volcano.

What are the effects and cause of a supervolcanol?
A super volcano is a huge sized volcano that can erupt, the eruption will create crater sized holes around the eruption.
Is Krakatoa a oceanic volcano?
Well after the eruption 1883 eruption Krakatoa was an Oceanic volcano, (around 1889) until it grew and regained it's height. It is now a land volcano.
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.
When was the first eruption of the vesuvius volcano?
The first known eruption is around 1800BC, during the Bronze Age.

The name of the Martinique volcano with a violent 1902 eruption is Mount Pelée. Its eruption in 1902 devastated the city of Saint-Pierre, killing around 30,000 people.
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.
What was the amount of materials expelled on mayon volcano eruption?
Around 60 million cubic meters of volcanic material were expelled during Mayon volcano's 2018 eruption. This eruption resulted in ashfall, pyroclastic flows, and lahars.
