Reventador volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 6 July-12 July 2005 (Continuing Activity)

Mi, 6. Jul 2005, 06:00 06:00 AM | VON: VN
As of 6 July, harmonic tremor, occasional explosions, and long-period and volcano-tectonic earthquakes continued at Reventador. Strong Strombolian fountaining was observed during the evening and one of the lobes of a lava flow (Lava number 5) was advancing down the caldera wall following the Río Marker. The flow abruptly slowed to ~20 m/day in comparison to flow-front velocities of ~70 m/day during 19-23 June, and ~50 m/day during 23-30 June.
Lava number 5 was ~1.2 km from a steep incline, where it could begin to rapidly descend to the alluvial fan where the highway and petroleum pipeline are located.

Based on information from IG, the Washington VAAC reported that an ash plume extended N of the volcano's summit on 11 July. No ash was visible on satellite imagery.
