Stromboli, The Volcano Helping To Predict When Others May Erupt

Stromboli, located in Sicily's Aeolian Islands, is one of the most famous volcanoes in the world, attracting tourists for its pristine black sand beaches. Yet due to its characteristics, including its uniquely consistent and predictable eruptions, it has also become an international reference point in the study of explosive dynamics.

Explosive volcanic eruptions can be so violent and sudden that they catch most monitoring networks by surprise. These phenomena pose not only a scientific challenge but a serious danger, especially for those volcanoes located in inhabited areas or visited by hordes of tourists.

Take the sudden eruptions of Mount Ontake in Japan in 2014 and White Island in New Zealand in 2019. Despite being constantly monitored, these volcanic eruptions resulted in more than 80 deaths among unsuspecting hikers.

One of the most famous explosive volcanoes in the world is Stromboli, located in the Aeolian Islands, off of Sicily. Its gentle yet spectacular explosions, which launch lava and incandescent fragments to several hundred meters in height, have been occurring at a nearly constant rate every 10-20 minutes for thousands of years.

This ongoing, moderate explosive activity is unique and allows for close observation of an erupting volcano. This is how Stromboli has become an international reference point in the study of explosive dynamics. Many of the technological innovations and methodologies commonly used in volcano observatories today were developed and/or calibrated on Stromboli.
