What signs indicate an imminent volcano eruption?
Signs of an imminent volcano eruption can include increased seismic activity, such as volcanic tremors, ground deformation, and gas emissions. In the case of Mount Etna, tremors were reported before the eruption, indicating heightened volcanic activity. Observing these signs can help authorities and residents prepare for potential eruptions.

How are scientists monitoring volcanic activity?
Scientists monitor volcanic activity using a combination of seismographs, satellite imagery, and gas emission analysis. These tools help detect changes in the volcano's behavior, allowing for timely warnings. For instance, the National Institute of Geophysics and Volcanology closely tracks Mount Etna's activity to provide updates and safety information.

What precautions should residents take during a volcanic eruption?
Residents near active volcanoes should have an emergency plan in place, including evacuation routes and supplies. It's essential to stay informed through local authorities and news updates. During an eruption, individuals should avoid areas near the volcano, wear masks to protect against ash inhalation, and follow evacuation orders promptly.

How does Mount Etna compare to other volcanoes?
Mount Etna is one of Europe's most active volcanoes, known for its frequent eruptions. Unlike some volcanoes that may remain dormant for long periods, Etna's activity is almost continuous, making it a significant focus for volcanologists. Other volcanoes, like Mount Spurr in Alaska, may show signs of unrest but are currently less threatening.
