The Bezymianny volcano experienced an eruptive episode on March 14-15, 2022 in Kamchatka. VAAC Tokyo detected an ash cloud at 4900 m. He drifted west.

Already in the past few days there have been signs of an impending eruption. Petropavlovsk volcanologists have warned that the volcano's seismicity has increased.

The Mirova site reports for these 14-15.03 weak to moderate thermal anomalies, between VRP 3 and 85 MW.

According to the Global Volcanism Program, the last period of volcanic activity in Bezymianny began on 05.21.2010 and is currently continuing, and is VEI 3.

This year, Indonesia is hosting the G20 Presidency. Yogyakarta Special Region is one of the venues where the G20 Presidency will be held.

With the effusive eruption of Mount Merapi, is it safe to visit the city of Yogyakarta? The PVMBG answers in the form of FAQs, of which here is the summary.

News of Bezymianny, Ili Lewotolok and Merapi

Based on current monitoring, there is no indication (as of 14.03.2022) of the possibility of a strong Merapi eruption.

Yogyakarta is safe. However, volcanic ash can reach the city, depending on the intensity of an eruption, and the direction of the winds.

Most tourist attractions are located outside the Merapi danger zone.

The Borobudur temple, located 27 km southwest of the volcano, is in a safe area. Volcanic ash can however reach it, always depending on the intensity of a strong eruption and the direction of the winds.
