IG reported that multiple lahars and mudflows descended drainages around Tungurahua on 14 October. A majority of the lahars traveled down drainages in the Pampas sector to the S, carrying blocks an average of 30-40 cm in diameter and up to 2 m in diameter. Other lahars and small mudflows descended drainages to the NW and W. On 19 October a small lahar descended the Bilbao drainage to the W.

The IG reported that clouds mostly prevented visual observations of Tungurahua during 3-9 September. On 3 September, a small lahar carried blocks down river drainages to the NW. Steam plumes rose 200 m above the crater on 6 September. On 8 September, a lahar descended a drainage to the S and carried blocks up to 50 cm in diameter.

Tungurahua volcano (Ecuador), activity update: increase in frequency and size of explosions, evacuations
Mon, 7 Jan 2008, 14:11
Tungurahua volcano's activity has been increasing over the past days. The Ecuadorian Insititute of Geophysics (IG) reports an increase in the frequency and size of ash explosions. IG interprets the present style of activity as related to constant degassing in an open-conduit system filled with vicsous magma. Sronger explosions alternate with near-constant emissions of gas and ash. ...more
