Crater.
Calande
The eruption of Toba volcano was caused by the release of built-up pressure from the magma chamber below the surface. This led to a catastrophic explosion that released an immense amount of volcanic ash and gas into the atmosphere.
It is the depression near to the summit of the volcano (or its side-shoot). A mature or eroded volcano may no longer show this. It was the outlet for the ejecta. Normally caused by the caldera (the source bowl of hot fluid) shrinking as the volcano runs out of puff.
The volcano that has caused the ash cloud is called Taal Volcano, located in the Philippines.
Much of the damage caused by Mount St Helens was blast damage from the initial explosion. This explosion was projected northward out of the side of the volcano, unlike other explosions, which have most of their force directed upward.Most of Pinatubo's damage was caused by ashfall, which was exacerbated by heavy rain from Typhoon Yunya, which impacted the Philippines during the eruption.
A "crater" : a hole or pit, caused by an impact (meteor or falling object), explosion, or volcano. Synonyms : cavity, hollow, depression, abyss (volcano only : caldera)

Crater
When you see a volcano there are usually if it is not dormant, hot air flumes, these are emitted by vents. Vents are part of the volcano and are mostly in the crater. A crater is a cup shaped hole, made by the previous eruption. Craters are also caused when an explosion happens.

A caldera is a depression in the land surface caused by the collapse of land into an emptied magma chamber as a result of an eruption of a stratovolcano. A caldera indicates that the volcano produced an extremely violent eruption.Caldera is also the Spanish language word for cauldron.
They are referred to as impact craters.
the effect of a volcano are te blow up , and this is caused by bombs
there is no wave caused by a volcano.
A low or sunken surface feature is called a depression. It can be caused by various factors such as erosion, weathering, or tectonic activity. Depressions can range in size from small dimples to large basins.
