	Left: 3 Aug. 2003 morning. T56B's activity, seen from the W, undergoes fluctuations on a time scale of 30-60 minutes. Here, strombolian eruptions have gained in violence with individual jets reaching around 50m height. (1.17 MB) Right: 3 Aug. Similar activity during the night. (273 MB)

	Left:5 Aug. 2003 day. Violent spattering occurs in episodes, piling up fresh material on the steep top of T68B. (1.04 MB) Right: 5 Aug. 2003 day. After its first collapse on late 2 Aug. the cone has fully re-grown by 5 Aug., ready for the next collapse... (684 KB)

		7 Aug. 2003 morning just before (l) and after (r) sunrise. Extremely close footage of the erupting lava lake inside the new crater. Now in daylight, the lava is appearing black and spatter from exploding lava bubbles from the boiling lava lake quickly builds up a parasitic flank cone - note the different morphology of the cone between these clips ca. 15 minutes apart!
