February 2006

Night of 25/26 February - The view was clear and there were a number of small rock falls/outbursts visible during the night. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows enhanced images superimposed over a daytime image of the crater for reference. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 24/25 February - There was an outburst of activity on the lavadome at 19:17, which corresponded with a M3.0 tremor recorded on the webicorders at the same time. Following the tremor multiple hotspots were visible for several hours.  The first movie below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows the same images superimposed over a daytime image of the crater for reference. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 23/24 February - The glow from the lavadome was visible through breaks in the clouds between 21:45-21:55, 22:45-23:35 and then from 05:15 until sunrise. There was a slightly larger tremor at 01:20, but the clouds unfortunately obscured the view around that time. I have edited out most the frames in which the glow didn't appear, to provide a smaller and hopefully more interesting animation. The first movie below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows the same images superimposed over a daytime image of the crater for reference. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 17/18 February - The sky was clear and the incandescent glow from the lavadome was visible throughout the night. Between 02:00 and 03:00 the crater rim was partially illuminated, presumably by the moon reflecting off the snow and ice in the crater.

Night of 15/16 February - The crater and lavadome were obscured by clouds briefly after sunset, but emerged at 19:23 and were visible for the rest of the night. There were several small outbursts related to small rock falls on the lavadome, with notable events occurring at 01:48 and 05:24. The latter corresponding to a larger tremor recorded on the SHW webicorder. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows the same images superimposed over a daytime image of the crater for reference. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 14/15 February - The clouds lifted at 20:00 to reveal a very active lavadome last night. At 20:21 there was a large outburst, corresponding to a tremor recorded on the SHW webicorder at precisely the same time. There were numerous small rock falls and outbursts that followed through the night and there was an active plume illuminated by the bright moon. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows the same images superimposed over a daytime image of the crater for reference. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 10/11 February - The view was clear and the glows from the lavadome were visible throughout the night. There were only a couple of very small outbursts with the glows flickering away fairly uniformly through the night. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows the same images superimposed over a daytime image of the crater for reference. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 09/10 February - There were numerous small rock falls visible during the night and one large fall causing a bright outburst at 06:00 - after which the entire lavadome was illuminated briefly. This event followed a larger tremor recorded on the HSR webicorder at 05:58. The moon, only a couple of days away from full, also illuminated the mountain for most of the night. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows the same images superimposed over a daytime image of the crater for reference. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 08/09 February - The sky was clear all night and the two most prominent glows from the lavadome remained fairly consistent over the course of the evening. There were a couple of small rock falls causing brief outbursts. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows the same images superimposed over a daytime image of the crater for reference (the glows are bright enough to be seen clearly on the stacked images and processing them further obscured too many details). The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 07/08 February - The lavadome was quite active last night, with numerous small outbursts caused by rock falls. There was also a brighter outburst that was began at 00:47, which followed a larger tremor at 00:43. Unfortunately, clouds rolled in around 02:30 and obscured the view from then on. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second was further enhanced to emphasise the brightness of the glows from the crater. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 06/07 February - The sky was again clear and multiple glows were visible overnight, as well as numerous small outbursts caused by rock falls. The USGS has posted some recent images that clearly show the result of the rock slides from the lavadome. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second was further enhanced to emphasise the brightness of the glows from the crater. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 05/06 February - The sky was clear and the glows from the lavadome were active throughout the night. The two main hotspots are clearly visible, with several small outbursts resulting from rock falls adding to the display. A notable outburst occurred at 3:23. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second was further enhanced to emphasise the brightness of the glows from the crater. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 02/03 February - The clouds finally lifted at 04:30 this morning to reveal two bright hotspots and a third that appeared intermittently. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second was further enhanced to emphasise the brightness of the glows from the crater. Only the frames from 4:30 until just before sunrise are shown, and I have slowed the speed down to 6 fps (equivalent of half an hour in real time per second).
