If your home is near a volcano, you should keep a survival kit. The survival kit should provide fresh water, clean clothes and food. Schools should have volcano evacuation training. If not they should be natural disasters, including volcanoes. If a volcano is starting to interupt, there should be an early warning. Alarms and signals are involved.
you remove the ash
A volcanic eruption starts with the build up of pressure in the magma chamber. A bulge in the crater may indicate a impending eruption. Earthquakes may also precede an eruption.
The loudest sound of a volcanic eruption was heard during the 1883 eruption of Krakatoa in Indonesia. The sound was heard over 3,000 miles away and is considered one of the loudest sounds in recorded history.
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.
The loudest volcanic eruption in recorded history was the 1883 eruption of Krakatoa in Indonesia. The explosion was so powerful that it was heard up to 3,000 miles away and led to the destruction of the island.
Clean up, usually. And rebuild or relocate.
you remove the ash
The eruption of Mount Pelée in 1902 devastated the town of Saint-Pierre on the island of Martinique, killing nearly 30,000 people and burying the city under ash and volcanic debris. While the immediate aftermath was chaotic and the area was largely abandoned for years, efforts to rebuild and clean up began over time. Today, Saint-Pierre has been partially restored as a historical site, with some remnants of the eruption preserved for educational purposes, but the full area affected by the eruption remains a reminder of the disaster.
Lava, cinder, arsh, gases, watervapour.
pressure builds up in the earth and pushes the magma up to the surface.
moving of tectonic plates and the build up of pressure within the volcanic mountain under the dried up lava which became rock after the previous volcanic eruption
The VEI (Volcanic Explosivity Index) of the Eyjafjallajökull eruption in 2010 was 4, indicating a moderate explosive eruption with a volcanic plume rising up to 10-25 km into the atmosphere.

The waters recede, and the people clean up and rebuild.
