2010 Daily Updates for the last week (or so...)
08 February - The images from the Volcanocam cameras show relatively clear views of Mount St Helens this morning. The issues with the updating of the webicorder traces continues, but no significant events have been recorded in the MSH area over the last 24 hours.
07 February - There's very little to report this morning, as for some reason all of the webicorder pages haven't been updated since a little before 05:00 PST yesterday morning. This isn't just for Mount St Helens, but all of the webicorder traces on the PNSN website. Meanwhile, the Volcanocam cameras continue to show whiteout conditions at MSH.
05 February - There were a few (very small) tremors on a couple of the Mount St Helens webicorders last night, but nothing of any significant magnitude. The M5.9 quake off the shores of northern California yesterday is clearly seen on the MSW webicorder traces (e.g. see the HSR chart). The Volcanocam images this morning are quite dramatic, with swirling clouds in the crater of the volcano.
04 February - All has been quiet over the last 48 hours - without any seismic events of note. The Volcanocam images continue to show cloudy conditions, with the occasional glimpse of Mount St Helens, but little else.
02 February - The Volcanocam Blog has an interesting tale of how the two cameras were brought back online and there is even some views of Mount St Helens on the Volcanocam images this morning! Seismic activity at MSH has remained low, with the one (small) event at 00:40 PST this morning (e.g. see CDF webicorder trace) not related to the volcano, but a couple of kilometers away near Dollar Corner WA.
01 February - The have been no notable seismic events over the last 24 hours. The Volcanocam images show a vague sense of Mount St Helens amongst thick clouds this morning, as winter storms pass through the area.
31 January - Seismic activity remains low, with a few, very small tremors appearing on the webicorders over the last 48 hours. There was one, more noticeable tremor recorded at 04:04 PST this morning (e.g. see the HSR webicorder trace). The images from the Volcanocam cameras have been obscured by clouds over the weekend. Something likely to continue well into the week.
29 January - Both of the Volcanocam cameras continue to function and are returning good clear images of Mount St Helens. Although the weather is forecast to deteriorate with lots of snow "likely" over the next few days. A small tremor was recorded on the MSH webicorders yesterday morning at 10:48 PST (e.g. see HSR & CDF traces), but this was situated a few kilometers away from MSH, near Mossyrock, WA.
28 January - The clear views of Mount St Helens continue on the HD Volcanocam and now the Classic Volcanocam is also back online. Seismic activity however, remains at background levels, with no notable events over the last 24 hours.
27 January - At last we have some clear views of Mount St Helens on the HD Volcanocam! The views should last for the next day or so, before more inclement winter weather arrives tomorrow night. Seismic activity remains at background levels.
25-26 January - The HD Volcanocam is greyed out with thick clouds this morning and seismic activity has remained low over the last two days. BTW, Happy Australia Day to all :)
24 January - The HD Volcanocam images this morning show a few rays of sunshine poking through the clouds and illuminating a snow clad Mount St Helens. Seismic activity remains low, with no significant events over the last day.
23 January - There appears to have been a (very) small tremor at Mount St Helens last night at 22:50 PST - most clearly seen on the HSR webicorder trace. The big news of the day is that the Volcanocam is back online! At least the HD Volcanocam is, the Classic appears to still have some unresolved issues...
...
13 June - All is quiet and a little grey - clouds persist at Mount St Helens and seismic activity remains at very low levels. Similar conditions at Mt Redoubt at present. For an interesting bit of weekend reading, you may like this story in New Scientist magazine about the possibility of a super-volcano lurking under Mount St Helens...
Most recent noteworthy events
18 May - The weather remains clear at Mount St Helens, but seismic activity remains at background levels. The views of Mt Redoubt (Alaska) are partially obscured by steam/ash this morning. I have just posted a new animation using images from the Hut webcam at Redoubt in the movies section showing the growth of the lavadome over the last couple of months. Interesting to see rock emerge from the vent over this time frame!
11 May - The clouds and wet whether have returned to Mount St Helens, so the views of the crater are now very limited. Seismic activity remains low, with only a few small tremors seen in the webicorders over the last 24 hours. Activity at Mt Redoubt (Alaska) continues to provide interesting views, such as this dramatic image from the Hut webcam from last night.
22 April - Seismic activity remain muted at Mount St Helens, and more clouds have moved into the area and obscured the view on the Volcanocam images. However, there is some developments from the Mt Redoubt (Alaska) webcams. On the night of 20 April several bright flashes can be seen on the webcam images! I have generated a small animation of the images from early in the day on the 20th until day time on the 21st. There's quite a bit to see in these animations - first of note is the large ice/snow collapse on the first day, the waterfall running in the lower centre of the frame and then the glow from rock falls in the growing lavadome. The first animation shows the night images at the actual brightness of the original images and its a little difficult to see. The second uses image processing to greatly enhance the glow and superimposes the glow on a reference image of the crater. Enjoy!
13/14 September - There were no significant changes overnight, but I have compiled a video of the last few days, which is available in the movie section. Lots of dust and several small rock slides on the crater walls are visible, as are a couple of visitors to the Volcanocam - LOL!
04/05 July - Another cloudy night with little activity to report. The large M7.7 quake in the Sea of Okhotsk is clearly visible on all of the webicorders just after 19:20 PDT [e.g. see JUN, VALT traces].
02/03 July - A thunderstorm passed over Mount St Helens last night and both of the Volcanocam cameras recorded lightning strikes on the mountain. The classic at 22:56 [see image] and a much better and more detailed image from the HD camera at 23:07 [see image]. You can also see the passage of the storm over the mountain as a band of increased background noise on the webicorders between 23:00 and midnight PDT. [e.g. see VALT, SWFL, JUN]
19/20 June - The sky was relatively clear and the moon once again illuminated Mount St Helens overnight, but activity within the crater remains at very low levels. I have posted an animation of Wednesday night's images in the Movies section. The full moon is overexposed in the HD Volcanocam images and looks far larger than it should. There are also numerous contrails from passing aircraft visible in the evening and night sky passing over Mount St Helens - perhaps adding weight to the idea that the bright lights seen over MSH on the night of 13 June may have been aircraft lights?
13/14 June - It was a clear night and there was no interesting activity from the crater of Mount St Helens, but there was something happening in the skies above! Around 02:21am this morning there was a bright object visible for a brief time - possibly an aircraft, satellite or fireball? I have also posted a movie of the complete night, from sunset to sunrise in the Movies section. Anyone have any idea what it may have been?
Note: All available movies of the nighttime activity of Mount St Helens, from 2004-2007 can be found in the archives.
