Detailed Description

The level of the lava lake sometimes changes abruptly. These cycles of rise and fall, which amount to a vertical change of around 15 m (about 50 ft), are occasionally triggered by rockfalls. Here, a small collapse from the vent wall triggers degassing and a drop in the lava level.
