Russia’s Most Active Volcano Spews Massive Ash Cloud

Overview of the Shiveluch Volcano Eruption

On April 11, 2023, the Shiveluch volcano, located on Russia’s Kamchatka Peninsula, erupted, sending an ash plume up to 10 kilometers high. This eruption prompted schools to close and residents living nearby to stay indoors. The Kamchatka Volcanic Eruption Response Team (KVERT) issued a code red Volcano Observatory Notice for Aviation, warning of a large ash cloud moving west of the volcano.

Massive Ash Cloud Poses Threat to Air Traffic

The eruption of the Shiveluch volcano produced ash explosions that could reach up to 15 kilometers high, potentially affecting international and low-flying aircraft. KVERT’s warning highlighted the ongoing risk posed by this activity and emphasized the need for caution in the region.

Precautions Taken by Local Authorities

In response to the eruption, Oleg Bondarenko, head of the Ust-Kamchatsky municipal region, ordered the closure of schools and advised residents in nearby villages to stay indoors. The ash cloud from the eruption spread over the villages of Klyuchi and Kozyrevsk, both more than 70 kilometers apart, according to Reuters.

Shiveluch Volcano: A History of Eruptions

The Shiveluch volcano is one of Russia’s largest and most active volcanoes, with an estimated 60 eruptions in the past 10,000 years. Its last major eruption occurred in 2007. The volcano’s frequent activity and potential for disruption make it a focal point for researchers and authorities monitoring volcanic activity in the region.

Studying the Shiveluch Volcano

The ongoing study of the Shiveluch volcano provides valuable insights into the causes of volcanic eruptions and their potential impacts on the environment and human populations. Researchers are constantly working to develop more accurate methods for predicting eruptions and mitigating their effects.


The eruption of the Shiveluch volcano on April 11, 2023, serves as a reminder of the potential dangers posed by active volcanoes. With the ash cloud reaching up to 10 kilometers high and posing a threat to air traffic, authorities were quick to take action, closing schools and advising residents in nearby villages to stay indoors. As one of Russia’s most active volcanoes, the Shiveluch continues to be closely monitored by researchers and authorities alike, who strive to better understand and predict volcanic activity in the region.
