Probably from the earthquake that happened when the crater hit the earth. The lava rushes to the surface, melting the crater, and it forms a volcano.
a crater volcano is...
It forms by volcanic activity in the vent of a volcano.
A caldera or crater.
The opening of the volcano is called crater. A crater may be large in dimension or deep. This is where the magma erupts.
Crater means in volcano that it is sort of like a not to deep hole either on or inside the volcano
A volcano crater filled with water---CALDERA
a crater can be formed anywhere in a volcano. its usually formed at the top though.
The volcanic craters that contain lakes are not extremely rare, however for a lake to form the volcano must have a low level of activity. If the temperature of the volcano gets too warm preceeding an eruption or shortly after an eruption the water will simply convert to steam and will not become a lake. However if the crater is cool enough and is enclosed, as long as there is a supply of water a crater lake will eventually form within the volcano.
