As of the 8th of June, the Universidad de Colima has reported that the seismic signals tremor type have remained in low levels. In the last week the signals associated to landslides remain stable as far as so large number and. In the nocturnal registry of images in infrared an increase in the incandescence in the top of the volcano with intense degasificacion was detected. They mainly continue the landslides towards the South, Southwestern sectors and the West. The measurements of inclinometry show a stable behaviour.
As of the 30th of May, the Universidad de Colima has reported that the seismic signals tremor type presented/displayed a greater amplitude with respect to reported day 28. They continue the signals associated to landslides and degasifications. The nocturnal registry of images in infrared detected around 70 landslides in 11 hours. 6 exhalations with incandescence were observed in addition. The landslides continue appearing by the South sector - Southwestern.
As of the 28th of May, the Universidad de Colima has reported that they continue registering seismic signals tremor type with presence of signals associated to landslides and degasificaciones. The camcorders registered in last the 24 hours incandescence and landslides by the south/west sector, with presence of sudden increases in the incandescence with permanence of several hours. The registry of COSPEC of the 26 of May was of 700 tons per day. In the last 24 hours the measurements of inclinometer did not show deformation of the volcanic building.
A strong increase in volcanic tremor at Colima caused the Scientific Committee on 18 May to evacuate hundreds of residents from several towns on the SW and SE flanks. Scientists also recorded changes in deformation, the chemistry of spring water near the volcano, and the composition of ejected rocks. In addition, heightened temperatures were recorded on infrared imagery. As of the 23rd of May, the Universidad de Colima has reported that during last the 24 hours tremor type as well as events of degasificaction with levels of the previous days continue the seismic signals such.
As of the 18th of May, the Universidad de Colima has reported that the associated seismic activity to the volcano has increased its level with respect to the last days. Also events have been registered daily explosive type and remarkable variations in associated seismic events to landslides. In the last days a greater frequency in landslides generated from the lava fronts has been observed. The lava front that lowers by the Southwestern flank, on the high parts of the ravine El Cordobán, has reached a distance of 1000 meters from the top.
As of the 2nd of May, the Universidad de Colima has reported that as of 29 April volcanism continued at Colima with incandescent lava avalanches travelling down the volcano's flanks and seismicity occurring that was indicative of small explosive events and landslides.
As of the 11th of April, the Universidad de Colima has reported that as of 6 April volcanism continued at Colima and more small explosion earthquakes were recorded than during the previous week. Incandescent lava avalanches, generated from the fronts of block-lava flows, continued to travel 2-3 km down Colima's S, SW, and W flanks, and sporadically down the E flank. In addition, block-lava flows extended 550 m down the SW flank and 2 km down the W flank
As of the 18th of March, the Universidad de Colima has reported that some ash and steam were observed over the volcano at 1750 GMT. This steam and ash was observed extending 30nm east of the volcano between 4,000 and 17,000 ft. Ash and steam can be seen in the Colima web-cam, however this emission is too small to be seen in satellite imagery through 1845 GMT. A faint hotspot is observed in the shortwave imagery.
On February 18th , the Universidad de Colima has reported that in the last hours they continued the landslides of incandescent material by South flanks, Southwestern and the West, which reaches about two kilometers from the top. The continuous lava front its advance in the southwestern flank on the high parts of the ravine the Cordoban, extending to one distances approximate of 70 meters from the top.
A lava dome has filled the crater of Volcán de Colima, México and provoked the first intermediate-size (up to 1 km of length) rock falls on the southern flank of the volcano that started at 17:21 (L.T) on February 4. The lava dome began to grow at the beginning of May, 2001 (BGVN, 26:05). The velocity of magma ascent sharply increased in October 2001, and by the end of January 2002, the total volume of the dome was estimated as 1,450,000 m3.
As of 0130 (0730 GMT), the 19th of December,, CENAPRED has reported that Mexico's Popocatepetl volcano spewed molten rock into the sky, causing small forest fires on its slopes in Puebla state where thousands of residents had been evacuated but many others refused to leave. Television images showed explosions of light above the volcano, which is 17,884 feet high and has been increasingly active in recent days, showering several communities with ash.
