What type of volcano is characterized by currently erupting or showing signs of future eruption?

An active volcano is defined as one that is currently erupting or shows signs that it may erupt in the near future. Characteristics of active volcanoes include ongoing lava flows, ash emissions, or seismic activity that suggests magma movement beneath the surface. These volcanoes are part of the geological processes that can continuously reshape the Earth’s landscape and pose significant hazards to nearby populations.

In contrast, inactive volcanoes do not display any activity and have not erupted for a considerable time, while dormant volcanoes are those that have not erupted in a long time but have the potential to erupt again. Extinct volcanoes are those considered unlikely to erupt again due to the absence of geological activity that could lead to an eruption. Understanding these classifications helps in assessing the risks associated with living near volcanic regions.
