In 1991, there were reports of volcanic activity but instrumental investigations showed no sign of unusual volcanic activity, such as intense fumarolic activity, felt earthquakes, fissuring at the volcano’s slopes, or smell of sulphur.
Another report of volcanic unrest was reported in 1993 but an aerial survey of the volcano proved no signs of activity.
