During 22-27 September, several small explosions occurred at Colima. The largest explosion took place on 27 September at 0507 and produced a plume to a height of ~3.8 km above the volcano (or 25,100 ft a.s.l.). The plume drifted WSW, depositing small amounts of ash in the cities of Colima, Villa de Álvarez, and Comala more than 30 km from the volcano. Due to the threat of lahars forming on the volcano's flanks, Universidad de Colima advised avoiding the ravines of La Lumbre, San Antonio, Monte Grande (in Colima state), and La Arena (in Jalisco state).

A group of scientists assessed the visible changes at Erta Ale on 26 September after activity began around 24 September. In comparison to observations made in November 2004, they found that the southern main crater/pit had widened significantly, with portions of the previous crater walls having collapsed into the lava lake. A new cone-shaped construct had grown within the southern main crater where there had been a platform. Read all- More about Erta Ale volcano

Erta Ale volcano in northern Afar, Ethiopia, well-known for its long-lived active lava lake that had occupied its crater up until 2004, erupted yesterday according to unconfirmed reports from local authorities. The eruption followed a series of earthquakes of up to 5.5. magnitude Richter scale that occurred in the area the day before.

Seismicity at Spurr during 16-23 September remained above background levels, but the overall rate continued to gradually decline. Preliminary data from a gas-sensing flight earlier in the week showed a substantial reduction in gas emissions compared to previous measurements taken in May 2005. The declining seismicity, reduced gas emission, and the changing summit-lake color (thought to reflect lower levels of acidity), all suggested a reduced level of volcanic activity.
