Ash emission from Galeras on 7 Aug (INGEOMINAS)
INGEOMINAS reported that during 31 July-6 August the magnitude and occurrence of earthquakes detected at Galeras had increased since the previous week. Gas plumes sometimes containing tephra rose from the crater. Observatory staff working near the crater reported a strong sulfur odor on 1 and 6 August.
On 3 August a steam plume rose 1.1 km above the crater. On 4 August ash emissions were observed in the morning, and at 1519 a seven-minute-long episode of tremor was accompanied by a gas-and-ash plume that rose 1.4 km above the crater and drifted N. Ashfall was reported in Genoy, 6 km NE. An ash plume rose from the crater on 7 August.
