Clouds of hot ash shot 1,000 meters (3,280 feet) into the sky and an avalanche of lava and scorching gases has spilled at least six times over the shaking slopes of Mount Merapi up to 3 kilometers (1.8 miles) since that morning as the volcano groaned and rumbled. said Hanik Humaida, the director of the Center for Volcanology and Geological Security in Yogyakarta.

A series of strong pyroclastic flows were released from the actively growing lava dome in the inner summit crater of the 2,968 meter high volcano, said Humaida.

Pyroclastic flow is a volcanic phenomenon that mixes turbulent and hot avalanches of hot lava rock, ash, and volcanic gases.

She described the volcano’s lava dome as rapidly growing, causing hot lava and gas clouds to flow on its slopes. Parts of the lava dome collapsed, sending rocks and ash down the southwestern flank of the volcano.

Mount Merapi has seen increased volcanic activity in recent weeks, and ash clouds stretched about 1.8 kilometers (1 mile) before sunrise. 2 miles) southwest of the volcano, said Humaida.

The Indonesian Center for Volcanology and Geological Security has not raised Merapi’s alert status, which is already at the second highest of four levels since the eruption began last November.

Villagers who live on the fertile slopes of Merapi are advised to stay 5 kilometers (3.1 miles) from the mouth of the crater and be aware of the danger of lava, the agency said Vulkan is located on the densely populated island of Java near the ancient city of Yogyakarta. It is the most active of more than 120 active volcanoes in Indonesia and has recently erupted repeatedly with lava and gas clouds.

Indonesia, an archipelago of 270 million people, is prone to earthquakes and volcanic activity as it is located along the Pacific Ring of Fire, a horseshoe-shaped series of seismic fault lines around the ocean.
