From Midnight To This Morning, 5 Times The Lava Of Mount Merapi Has Slid To The Southwest

JAKARTA - The Geological Disaster Technology Research and Development Center (BPPTKG) explained that Mount Merapi on the border of Yogyakarta and Central Java released five incandescent lava flows to the southwest.

The incandescent lava fell on Wednesday, July 6 with a maximum distance of 1,200 meters (1.2 km) to the southwest, starting at 00.00 to 06.00 WIB.

Head of BPPTKG Agus Budi Santoso explained that during the observation period, Merapi also experienced 23 earthquake avalanches with an amplitude of 3-14 millimeters (mm) for 42-111 seconds, one earthquake gust with an amplitude of 3 mm for 18.3 seconds, and two earthquakes with an amplitude of 3 mm. multiple phase earthquakes with an amplitude of 3-4 mm for 7.8-8.2 seconds.

On Wednesday morning, the weather at Merapi was sunny and cloudy. The wind is blowing weak to moderate to the north and the air temperature is 13-19 degrees Celsius with an air humidity of 70-83 percent, and air pressure is 625-687 mmHg.

"The smoke from the weak pressure crater was observed to be white with medium intensity and 20-50 meters high above the crater peak", Agus said, quoted from Antara.

Based on the results of the morphological analysis conducted by BPPTKG in the period 24-30 June 2022, no changes in height were observed, neither the southwest dome nor the central dome.

The volume of the southwest lava dome was recorded at 1,551,000 cubic meters and the central dome at 2,582,000 cubic meters.

It rained at the Mount Merapi Observation Post with an intensity of 40 mm per hour for 30 minutes at the Kaliurang Post on June 24, 2022.

Until now BPPTKG still maintains the status of Mount Merapi at Level III or Alert.

Lava flows and hot clouds from Mount Merapi can impact areas in the south-southwest sector which include the Boyong River (a maximum of five kilometers) and the Bedog, Krasak, and Bebeng rivers (a maximum of seven kilometers).

In addition, lava flows and hot clouds from Mount Merapi can impact areas in the southeastern sector which include the Woro River (a maximum of three kilometers) and the Gendol River (a distance of five kilometers).

If the volcano experiences an explosive eruption, then the ejection of volcanic material can reach an area within a radius of three kilometers from the top of the mountain.
