Seismic activity at Galeras volcano 28 June 2012
Seismic activity at Galeras volcano 28 June 2012
Tremor and small earthquakes continue to occur at Galeras volcano. Some of the seismic signals (such as the one early on 28 June) look like screw-shaped tornillos, which in the past have often preceded eruptions.
Summary 20-26 June
During 20-26 June, the magnitude of earthquakes detected at Galeras had decreased since the previous week, but seismicity continued to indicate ash and gas emissions. During 19-22 and 24 June cameras recorded gas-and-ash emissions that drifted NW.

during 5-19 June seismicity at Galeras had increased in both magnitude and frequency since the previous week-long period, and indicated continuing ash and gas emissions. On 5, 6, and 12-19 June cameras recorded gas-and-ash emissions; an ash plume rose 1.4 and 2.4 km above the crater on 14 and 17 June, respectively. Ashfall was reported in Sandona (13 km NW), Samaniego (32 km NW), Mapachico (8 km NW), and Genoy (5 km NE). Sulfur dioxide emissions were moderate to high. ... read all

The Colombian volcano monitoring institute INGEOMINAS has raised the alarm level for Galeras volcano, after a number of so-called tornillos, a characteristic seismic signal often preceding eruptions at Galeras, were detected in recent days. Tornillos consist of a screw-driver shaped signal of rapdily increasing and then slowly decreasing harmonic tremor and preceded most eruptions of Galeras between 1992 and 2010. ... read all
