Daily Updates for the last week
21/22 July - Thick cloud/fog rolled into the valley early last night and completely obscured the views of Mount St Helens overnight.
20/21 July - No real news to report from the last 24 hours - the views remain clear from the Volcanocam cameras and seismic activity remains low.
19/20 July - The clouds lifted yesterday around noon and the view of Mount St Helens has been clear since then. Seismic activity remains very low and there has been little visible activity from MSH over the last 24 hours - a few small rock falls on the crater walls raised a little dust, but that's about all...
18/19 July - Thick clouds obscured the view of MSH through all of last night :-(
17/18 July - The full moon illuminated the crater throughout last night, but low clouds filled the valley in the foreground and this morning the view is completely obscured. Although the view should clear as mainly sunny weather is forecast for the next five days. There were two medium quakes off the coast of Oregon yesterday afternoon (M5.7 & M5.5), just before 16:00 PDT, which were clearly shown on the MSH webicorders, e.g. see VALT
16/17 July - The moon, the stars, and nice views of Mount St Helens from the Volcanocam cameras overnight, but very low levels of activity, with nothing of note to report.
15/16 July - The two-days-from-full moon passed low over Mount St Helens last night and was visible in images from both the HD and Classic Volcanocams. Seismic activity remains low, with slightly elevated levels of activity at those stations close to the glacier, mainly indicating movement of ice.
14/15 July - There were a few high clouds and glimpses of the rising moon (on the HD Volcanocam) last night and the views of the crater remain clear. The forecast is for generally clear weather over the next few days. Seismic activity remains at low levels.
13/14 July - The clear views of Mount St Helens continue from the Volcanocam cameras. There has been no notable activity over the last 24 hours.
12/13 July - The clear sunny weather continues, as does the pause in any significant activity within the crater. Blowing dust and small rock slides are the only notable events to be seen over the last 24 hours.
11/12 July - Another clear day with the occasional rock slide on the walls of the crater and quite a bit of dust being kicked up by strong winds. Seismic activity remains at the low levels of recent days.
10/11 July - Summer has definitely arrived at Mount St Helens and the clear views of the mountain should remain over the weekend, with the possibility of some clouds appearing on Sunday night. Activity remains low, with no notable events over the last 24 hours. Have a great weekend everyone!
09/10 July - The clear weather continues affording great views of Mount St Helens from the Volcanocam cameras. Activity, however, remains low with similar a pattern to what we have seen over the past weeks, with some low level activity in the crater related to small rock falls and ice movement in the glacier. No notable seismic events over the last 24 hours.
Most recent noteworthy events
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.
