Sinabung , Indonésie :  White plumes rose as high as 500 m above the crater.

 

PVMBG reported that foggy weather sometimes prevented visual observations of Sinabung during 22-29 June. White plumes rose as high as 500 m above the crater, and lava flows on the flanks were incandescent as far as 3 km S and SE. Multiple pyroclastic flows per day during 22-26 and 28 June traveled 2.5-4 km down the flanks from the SSE to the SE. One pyroclastic flow was observed on 27 June. Ash plumes rose generally 3.5 km on most days, drifting E, SE, and S, although an ash plume rose as high as 5 km on 25 June.

Seismicity consisted of avalanche signals, low-frequency and hybrid events, tremor, tectonic events, and volcanic earthquakes; RSAM values increased due to an increase of avalanche signals. Deformation data showed a trend of inflation. The Alert Level remained at 4 (on a scale of 1-4), indicating that people within 7 km of the volcano on the SSE sector, and within 6 km in the ESE sector, should evacuate.
