Raung volcano (Eastern Java) - Smithsonian / USGS Weekly Volcanic Activity Report for 27 July-2 August 2022 (New Activity / Unrest)

Thu, 28 Jul 2022, 10:00
10:00 AM | BY: VN
According to PVMBG an eruption at Raung at 1719 on 27 July produced a gray ash plume that rose 1-1.5 km above the summit and drifted W and NW. On 28 July a thermal anomaly in the crater was identified in satellite images and data from the GPS network indicated inflation, likely from an intrusion of magma. Seismicity on 29 July was dominated by continuous tremor.
The Alert Level was raised to 2 (on a scale of 1-4) that same day, and the public was warned to stay 3 km away from the crater.
