2014 Unrest
Ambang volcano was raised to level 2 alert on 3rd July 2014 after an increase in shallow earthquakes. A 1.5 radius exclusion zone was placed around the crater.

2013 expedition
Ambang volcano was climbed by John Seach during June 2013. Two areas of strongly active fumaroles were observed on a fissure zone visible on the southwest side of the volcano. The westernmost fumarole emitted a thin white plume to a height of 100 m. The easternmost fumarole emitted pulses of white vapour to a height of a few tens of metres. The summit of ambang volcano was reached after a climb from the northeast side. The summit area was heavily forested. During the descent of the volcano on the northeast flank, a strong smell of sulphur was detected but the source not identified. The high levels of fumarolic activity at Ambang volcano indicate future eruptions are possible. A magnitude 5.7 earthquake hit 116 km SSE of Ambang volcano on 27th June 2013.

2005 Activity
A phreatic eruption was reported at Ambang volcano in 2005.
