0 a mountain with a large, circular hole at the top through which lava (= hot liquid rock) gases, steam, and dust are or have been forced out:

Erupting volcanoes discharge massive quantities of dust into the stratosphere.
1 a mountain made from burned materials that may throw out hot rocks and lava (= hot liquid rock) from a hole in its top
The long-dormant volcano has recently shown signs of erupting.
The pictures were an eloquent reminder of the power of the volcano.
Since the volcano last erupted, many houses have been built in a dangerous position on its slopes.
The volcano there, after being dormant for 400 years, erupted in 1995.
The study of these very small volcanoes is often complicated by the limited distribution of their deposits and by reworking/erosion processes.
Further we compare and discuss magnetic reversal time scales with biodiversity and the outbreak of super volcanoes, which affected the biosphere.
