Daily Updates for the last week (or so...)
03 July - All remains clear and fine, with great views of Mount St Helens on the Volcanocam images. Seismic activity remains low, with only a few small rumblings from the glacier showing up on the most sensitive webicorder traces.
02 July - Conditions remain clear, with no change in levels of seismicity over the last 24 hours.
01 July - Conditions remain clear with good views of Mount St Helens on the Volcanocam images over the last 24 hours. The large seismic signal on the webicorders just after 5:09am PDT (e.g. see HSR trace) was not associated with MSH but an M3.7 quake located near Puget Sound. BTW - Happy Canada Day to all!
30 June - Conditions remain similar to recent days, clear weather and background levels of seismic activity.
29 June - Another quiet 24 hours at Mount St Helens, seismic activity remains at background levels, apart from the indications of ice movement in the glacier at the VALT and SWFL stations. The weather remains clear. The weather has also cleared somewhat at Mt Redoubt (Alaska), with snow covering much of the crater and lavadome and strong steaming evident from the webcam images.
28 June - After some overnight clouds, the view of Mount St Helens is clear again on the Volcanocam images. Seismic activity remains low.
27 June - The weather has cleared and it looks to be a pretty nice day at Mount St Helens. Activity remains very low, with no notable events over the last 24 hours. Conditions at Mt Redoubt (Alaska) also remain quiet, although above background levels.
26 June - Another uneventful 24 hours at MSH. Seismic activity remains at background levels and cloudy conditions continue...
25 June - The clouds have returned and the view of MSH is blocked by clouds this morning, but should clear again tomorrow. Seismic activity remains low, with nothing unusual to report.
....
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.
