JAKARTA - The Klyuchevskaya volcano in the Kamchatka region, Russia, erupted again and spewed volcanic ash up to a height of 7.5 kilometers above sea level.

The eruption has the potential to disrupt air traffic, the Institute of Volcanology and Seismology said in a statement from the Far East Branch of the Russian Academy of Sciences on Monday, August 4.

"At 15:55 local time (10:55 WIB), the eruption lifted ash from Mount Klyuchevskaya to a height of 7.5 kilometers above sea level with volcanic ash spreading stretching as far as 50 kilometers northeast of the mountain," the academy said.

"Flight color coding: orange. Mountain activity is harmful to local and international flights," he continued.

This marks the second ash eruption from the volcano on Monday. The previous eruption, recorded hours earlier, reached an altitude of 6.5 kilometers.

On August 2, the regional branch of the Russian Ministry of Emergency Situation reported ash bursts from active volcanoes, namely Klyuchevskaya, Badminton, Karymsky, Bezymianny, and Kambalny with a height of between six and 10 kilometers.

Tourists and residents of Kamchatka are advised to avoid travel and climb within a radius of 10 kilometers from the top of the volcano.

On July 30, an earthquake measuring 8.8 magnitude occurred off the coast of the Kamchatka Peninsula which became the strongest earthquake in the region since 1952.

The Klyuchevskaya Volcano has a height of 4,850 meters above sea level and is located in the Ust-Kamchatsky district, Kamchatka. The previous eruption was recorded in April 2025.
