Why can earthquakes be a warning sign that a volcano eruption is going to happen?

you guy are dumb


What is the first sign of a tsunami?

The first sign of a tsunami is often a strong earthquake or underwater volcanic eruption. If you feel strong shaking that lasts for an extended period, see water receding quickly from the shoreline, or hear a loud roaring sound from the ocean, these could be early warning signs of a tsunami. Pay attention to official warnings and evacuate to higher ground immediately if advised to do so.


What was the warning for Mount Tambora?

The warning for Mount Tambora was due to increased volcanic activity leading to a significant eruption. The warning was related to the potential hazards such as pyroclastic flows, ash fall, and possible tsunamis that could result from the eruption. Evacuation orders were issued to nearby communities to ensure their safety.


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.


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.
