you are asking a seemingly simple question but it has a complex answer. Prior to an eruption you have the forming of the caldera. Then you have the eruption: here are some effusive eruption, central vent eruption,fissure eruption, subaqueous eruption, sub glacial eruption, pyroclastic eruption, ash-flow eruption. The most spectacular of all of them is the pyroclastic eruption. It throws off viscous gas-rich magmas and producesw a great deal of solid volcanic fragments. A volcanic eruption after is called clean up. The included link about Mt St Helens eruption will give you an idea on the potentially explosive power of a volcano.
lapilli. Lapilli are small fragments of magma expelled during a volcanic eruption that solidify before hitting the ground. They are larger than volcanic ash but smaller than volcanic bombs.
Before a volcanic eruption, updates typically include seismic activity monitoring, gas emissions measurements, ground deformation analysis, and visual observations of the volcano's summit. These updates help scientists to assess the volcano's behavior and provide early warnings to at-risk communities.
Not usually. Although earthquakes often occur before a volcanic eruption, they are not the cause. The earthquakes are the result of magma (molten rock) moving underground leading up to an eruption. A few volcanic eruptions are thought to have been triggered or initiated by earthquakes, but this is not the typical case.
The earthquakes are caused by the movement of magma underground and the breaking of rocks by that magma.
Before a volcanic eruption, it is important to evacuate to a safe location if advised by authorities, create an emergency preparedness kit, and have a family emergency plan in place. After the eruption, individuals should stay indoors to avoid ashfall, wear protective gear if venturing outside, and follow local guidelines for cleaning up ash and debris.
