Webcam images of Dempo posted in the daily PVMBG reports showed possible patches of discolored water or material floating on the surface of the crater lake during 27-29 August. The Aviation Color Code was raised to Orange (the third color on a four-color scale). The Alert Level remained at 2 (on a scale of 1-4), and the public were reminded to stay 1 km away from the crater and as far as 2 km on the N flank.
PVMBG reported that an eruption at Dempo occurred at 2105 on 21 August, but no ash emissions were observed. A video posted on social media showed a Surtseyan eruption through the crater lake, with steam plumes and dark material being ejected above the lake. The Aviation Color Code was raised to Orange (the third color on a four-color scale).

A explosion occurred yesterday morning inside the summit crater of the volcano. At 9.05 a.m. local time, dense jets of light to dark-gray ash and rocks, mixed with white steam, were ejected in a sudden, violent blast from the crater. The ash plume, also seen from people near the base of the volcano, rose a few hundred meters and quickly dissipated after the end of the eruption.
