12 December

Arrived at the village of Cemara Lawang midday, which are located 2km from Bromo. The weather was cloudy/foggy, and only allowed sporadic views of Bromo today.

Activity of the Volcano

When observable, the volcano was seen emitting ash plumes, that reached heights of 200-400m. The ash-plumes seem to contain only small amounts of ash. However some ash-fall was reported in Malang today, 50km SW of Bromo. The intensity of the eruption seemed to be the same throughout the day. No crater glow was observed.

14 December

Activity of the Volcano

Activity is still high, but the activity seem the same as yesterday. The eruption plume didn’t seem to reach the same heights as yesterday. Today I believe it varied between 300-700m above the volcano. Wind levels was a bit stronger today, and this element might have contributed to the decreased height of the plumes.
