Huge Eruption of Italian Volcano Sends Ash Hundreds of Feet into the Air


Huge Eruption of Italian Volcano Sends Ash Hundreds of Feet into the Air

The Stromboli volcano launched tons of ash, hundreds of meters high in Italy. It is not uncommon, since it has been in operation for at least 2,000 years, earning the nickname “Mediterranean lighthouse”. In fact, it is considered one of the most active in the world, located in the Aeolian archipelago, on the north coast of Sicily.

Stromboli had a violent outbreak, different from what it had recently been experiencing. The cameras of the Istituto Nazionale Geofisica e Vulcanologia (INGV) managed to catch all the details of this avalanche of overheated ash, fragments of lava and still gas flowing down the hill.

An explosion on the slopes of Stromboli sent an avalanche of pyroclastic flow rushing down the side of the Italian volcano on November 16th.

The stronger-than-usual explosion was captured on cameras operated by the Istituto Nazionale Geofisica e Vulcanologia (INGV). Imagery shared by Il Mondo dei Terremoti on Twitter shows the eruption in real-time; video captured by infrared cameras that shows the ultra-hot initial eruption and the slightly cooler cloud of ash and gases careening downslope. This avalanche of hot ash and gases is known as pyroclastic flow.

Stromboli is a volcanic island 3 miles (2 kilometers) in diameter and 3,038 feet (926 meters) tall. It’s regularly active, belching little bombs of lava and ash from its summit craters on nearly an hourly basis. Monday’s eruption, which occurred at 10:17 a.m. local time, according to Volcano Discovery, was larger than the volcano’s usual fare. It sent a cloud of ash towering several hundred feet into the air. A light rain of ash and pumice then fell on the surrounding area, according to Volcano Discovery. The pyroclastic flow sped down a slope of broken rock, or talus scree, called Sciara del Fuoco. Though a few hundred residents call Stromboli home, the eruption did not affect any homes or buildings.

This is the second above-average explosion on Stromboli in the past two weeks. On the evening of Nov. 10, INGV’s cameras captured another large eruption at the volcano.

It’s not clear whether these explosions indicate a long-term trend toward more activity at the volcano. According to the Smithsonian Institution’s Global Volcanism Project, Stromboli’s northernmost vent area and its south-central vent area were also active as of late October, throwing fine air and rock up to 820 feet (250 m) in the air multiple times an hour over the course of a week.

According to Oregon State University, the volcano rarely causes loss of life. Its most dramatic eruption in recent history occurred in 1930, when pyroclastic flows and scalding seawater killed four people. The most recent death on the volcano was in 2019, when a 35-year-old hiker from Sicily was struck by erupting rock and killed.
