Eruptions happen when magma rises to the surface of the crust and eventually breaks free.
The eruption in Eyjafjallajökull was caused by the interaction of magma rising from beneath the Earth's crust with ice and water, resulting in explosive ash and lava eruptions. The melting of ice due to the heat of the magma led to a rapid buildup of pressure, eventually culminating in explosive eruptions.
Plinian eruptions are more violent than Hawaiian eruptions because they involve highly viscous magma that traps gas bubbles, leading to increased pressure buildup and explosive eruptions. In contrast, Hawaiian eruptions involve less viscous magma with low gas content, allowing the gases to escape easily and resulting in more effusive, less explosive eruptions.
When eruption types are arranged from most destructive to least, it is in descending order.
Violent volcanic eruptions are common where magma has a high gas content and viscosity. The pressure from trapped gases builds until it explosively releases, causing explosive eruptions like Plinian or Pelean eruptions. These eruptions often result in ash plumes, pyroclastic flows, and lahars.
Lahars can occur anytime there is a volcanic eruption or when large amounts of rainfall or snowmelt mix with volcanic debris on a slope. Their frequency varies depending on the volcanic activity and local weather conditions, but they can happen during or after an eruption. Monitoring volcanic activity and having early warning systems in place are essential to mitigate their impacts.
Volcano eruptions happen in many places but they mostly occur in Hawaii.
yes! volcanic eruptions happen on mars NASA
Yes.
Generally not. Explosive eruptions may happen occasionally, but most eruptions are effusive.
once in a decade or so
eruption can happen almost every single day- NBBCRAZY

yes
Earthquakes and volcano eruptions.
Where ever there is a vertical vent fault in the tectonic plates.
