There are three main types of volcanic eruptions: effusive, explosive, and collapse. Each type of eruption is characterized by a different style of activity. Effusive eruptions are the most common type of volcanic eruption. In an effusive eruption, lava flows out of the volcano in a relatively calm and steady fashion. The lava is often thin and fluid, and flows down the sides of the volcano in rivers or streams.
Explosive eruptions are much less common than effusive eruptions, but they can be much more violent. In an explosive eruption, magma is blasted out of the volcano at high speeds. The magma is usually thick and sticky, and contains a lot of gas. The explosive force of the eruption can cause the magma to fragment into small pieces, which are then hurled into the air.

What are the different types of volcanic eruptions and what causes them?
The three main types of volcanic eruptions are effusive, explosive, and collapse. Effusive eruptions occur when lava flows out of the volcano in a relatively calm and steady fashion. The lava is often thin and fluid, and flows down the sides of the volcano in rivers or streams. Explosive eruptions are much less common, but can be much more violent. In an explosive eruption, magma is blasted out of the volcano at high speeds.
The magma is usually thick and sticky, and contains a lot of gas. The explosive force of the eruption can cause the magma to fragment into small pieces, which are then hurled into the air. Collapse eruptions occur when the side of a volcano collapses. This can happen due to a number of reasons, including an explosive eruption, heavy rainfall, or an earthquake.
How do scientists study volcanoes to predict eruptions and warn people nearby?
Scientists study volcanoes to predict eruptions and warn people nearby by monitoring seismic activity, ground deformation, gas emissions, and changes in the water level. Seismic activity is monitored using seismometers, which measure the shaking of the ground caused by earthquakes. Ground deformation is monitored using GPS, which can measure changes in the shape of the land. Gas emissions are monitored using gas sensors, which can detect changes in the composition of the gases being emitted from the volcano. Changes in the water level are monitored using tide gauges, which measure changes in the height of the water in a particular location.
