From noon on Saturday, September 1, 2012, there was an increase in the number of earthquakes associated with the movement of fluids inside the volcano. These earthquakes are long period events of small energy mainly registered by the station located in the northwestern flank of the volcano. The highest value corresponds to 532 long period events recorded between 2 and 3 September. Larger explosions were not generated. On 1 and 2 September, the gas monitoring network detected a SO2 degassing rate of 9000 to 7000 tons per day, respectively. On the surface there has been steam and gas emissions during these days, with sometimes minor ash content. In the evening, the presence of incandescence in the crater and ejections of incandescent blocks could be seen by naked eye. Associated with this activity are generated sporadic mild roar. Between August 30 and September 2 there have been reports of minor ash falls in sectors located southwest of the volcano, as Manzano and Choglontús. Cloud cover conditions in the area of the volcano are almost permanent.

Seismic activity has increased since the beginning of the month again, however not reached previous levels and IG describes it at moderate. Surface activity have been mainly steaming, creating a 300 m high plume, and few weak explosions, causing light ash fall.

Since the beginning of this week Tungurahua's seismic activity was characterized by internal fluid movements (LP events) and volcano-tectonic earthquakes (VT) (rock fracturing within the volcanic edifice). There were 8 quakes under the northwestern flank of Tungurahua at depths between 3-13 km below the summit. It is worth noting that some of these events were felt by residents of CUSU, Juive Grande, Puntzán and Bathrooms in the evening of 26 August at 20h26 (local time) and on 29 August at 18h46 (local time) and 30 August at 09h32 (local time). These local events had magnitudes between 2.5 and 2.6. The other quakes were only recorded instrumentally. ...

A rising tremor signal suggests ongoing ash emissions and small explosions, but bad weather prevents observations. The recent moderate rain falls have fortunately not caused lahars, IG mentions.
