Sinabung (Sumatra, Indonesia): Activity at the volcano has been a bit lower during the past days, especially when compared to the first half of the past week. It is certainly too early to say whether this is a sign of a possible approaching end of the of the eruption or just a temporary or perhapy only apparent decrease.
VSI has published a detailed report about their seismic and other monitoring data up up 17 Jan. It doesn't include the past days, but illustrates the marked peak in activity during 10-15 Jan. Deformation and other monitoring data have been limited by several stations having become non-operational because ash covering the solar panels and other technical difficulties in maintaining them.

Marapi (Western Sumatra, Indonesia): New ash emissions occurred from the volcano's summit crater this morning at 10am local time, Antara News reported. The eruption , back into eruption. Similar small eruptions have been observed during the past years and the current status of the volcano remains at level 2 (out of 4).
Climbers are advised not to approach the crater to within 3 km radius because similar (probably phreatic) explosions can occur with little warning.
