To know if a volcano is active, scientists usually look for signs of activity such as seismic activity, gas emissions, and recent eruptions. According to the United States Geological Survey (USGS), a volcano is considered active if it is currently erupting or showing signs of unrest, such as an increase in earthquakes and gas emissions. A volcano is considered dormant if it has not erupted recently but still has the potential to erupt in the future. An extinct volcano is one that has not erupted in the last 10,000 years and is not expected to erupt again. It's important to stay informed about the status of volcanoes in your area and follow the guidance of local authorities in the event of an eruption warning or evacuation order.
