Activity levels at Semeru have picked up pace the last months, as was observed last month visually and also seen trough continious hotspot activity by the MODIS thermal monitoring system. Rockfall from the growing lava-dome was observed on this visit as well, and the activity level looked similar to my visit on 27-28th August. I did not manage to view of photograph the volcano during the night, as the area was covered in fog all night until early morning after sunrise.

Activity levels at Semeru have picked up pace the last month. During a visit on 27-28th June I observed a contant crater glow caused by incandescent material in the crater, small strombolian activity and rockfall from the crater-area/lava dome.

Semeru volcano have shown a increase since last visit. The eruptions are more frequent (every 30min to 1 hour) and it`s plumes are more ash-rich than the ones observed during 2013.
9th March 2014.
Only witnessed two small eruption plumes from Semeru on this visit, and those happened with approximately 1 hour between them. The eruption clouds seem to contain little or no ash, these days. Recent reports, however, states that a lava-dome is growing in the crater of Semeru.

Photos taken from villages in the district of Lumajang, south of Semeru. With the month of october marking the start of this year`s rainy season, unfortunately the weather wasn`t optimal, had no possibilitiy to catch any eruptions during night time.
Type of activity: Mt. Semuru sent up ash cloudes every 30+/- minute.
Trucks collecting fine volcanic sand/dust of at the base of Semeru. The sand is used locally to produce cement for house building, however mostly transported to large cirtes in the vicinity, like Malang or Surabaya, to be sold for the same purpose. The riverbed seen on the photo contains not only sand/ash brought by lahars from Semeru but also bigger volcanic blocks.
