active volcano
Currently erupting peak
An active volcano is one that has erupted recently or shows signs it might erupt again—seismic activity, gas emissions, or ground deformation.
The distinction from dormant or extinct volcanoes is imprecise; geologists may classify any volcano that has erupted in the past ten thousand years as active.
Mount Etna is one of the world's most active volcanoes.
