Daily Updates
13/14 May - Mount St Helens is still shrouded in clouds this morning, but as mentioned yesterday, the forecast is for clear weather tonight and in the coming days! There appears to be a slight increase in seismic activity as shown on the VALT webicorder. Indications of the slightly increased intensity is that some of the same tremors are (just) visible on the SEP and HSR recordings. It is not however clear whether this is any more than movement of ice within the glacier as the weather warms up.
12/13 May - There were partial views of the crater last night from the Volcanocam cameras, with no notable activity to be seen. The views should improve after Wednesday as warmer clear weather is forecast for later in the week and with the full moon approaching. Seismic activity remains at the low levels of recent weeks.
11/12 May - There was little activity situated at Mount St Helens, the cloudy weather continues and local seismicity remained low. However, the M7.8 quake in China is clearly recorded on the MSH webicorders. e.g. see VALT webicorder trace.
10/11 May - A very quiet night at Mount St Helens. Clouds obscured the view and there were no notable seismic events...
09/10 May - Things remained fairly quiet over the last 24 hours. Views of the crater were relatively clear, with only high clouds blocking the views of the sky. However, there was no notable visible activity in the crater. Most of the MSH webicorders showed very little activity last night, apart from the VALT webicorder, which is situated in the crater. There were a number of small tremors between 1800 - 23:00 PDT - but as they didn't register strongly on other seismometers on the mountain they must have been quite localised, most likely movement in the glacier.
08/09 May - Another uneventful and typical night at Mount St Helens - clouds and little seismic activity. The weather is forecast to improve today and tomorrow, before the clouds and a possibility of snow returns later on Saturday. It seems winter doesn't want to relieve its grip on the Cascades just yet...
07/08 May - It was another cloudy night at MSH, with no views of the crater and no notable seismic activity related to Mount St Helens.
06/07 May - There were no views of Mount St Helens last night from the Volcanocam cameras due to thick clouds obscuring the view. Seismic activity remains low, with the only notable event over the last 24 hours being another small quake off the coast of Oregon appearing on the MSH webicorders.
05/06 May - The weather has turned and clouds are blocking the view of Mount St Helens this morning. Activity remains low, with a few small tremors showing up on the VALT webicorder, likely indicating movement in the glacier rather than a resumption of lavadome growth.
04/05 May - The weather is currently clear, but activity remains at the very low levels of recent weeks. There were no notable seismic or visible events over the last 24 hours.
03/04 May - There's a little activity shown on the VALT webicorder, most likely related to movement of ice in the glacier. One larger tremor around 02:52 UTC is related to a M4.6 quake off the coast of Oregon. There was no notable visible activity from the crater last night and there are glimpses of the crater on the Volcanocam cameras this morning.
02/03 May - The cloudy weather has returned and the view of Mount St Helens is obscured. Seismic activities remain very low.
01/02 May - Maybe I was a little quick to criticize the Gnome's work - the snow is gone and we now have clear views of Mount St Helens (for as long as the clear weather lasts anyway). Seismic activity remains very low, except for the trace of the M6.5 quake in Alaska that appears on all the functioning webicorders. e.g. see VALT, HSR or CDF.
30/01 May - Well, the snow Gnome put up a mighty fight, but in the end succumbed to the onslaught of snow. Yesterday morning he was there, by the afternoon he was gone. Believe it or not, there's still more snow forecast in the coming days. Seismic activity remains low & views of the crater were obscured by clouds, but not Gnomes, last night...
29/30 April - It's snowing again and someone has decided to do something about it! I don't quite know whether "I will get the snow" means he's going to clear it away, for a quick glance at the Volcanocam this morning reveals that the snow is getting the upper hand... In other news, seismic activity remains low - the large quake registered on the webicorders last night (e.g. see VALT) was due to a M5.2 quake in Northern California.
28/29 April - there were no views of Mount St Helens last night due to cloudy weather and seismic activity remains low. Although another small M4.1 quake off the coast of Oregon can be seen on a few of the MSH webicorders. e.g. see HSR trace
27/28 April - Clouds have returned to Mount St Helens, so no views of the crater last night. Seismic activity remains low, with one larger quake on the webicorders last night related to a small M2.7 quake nearby in Oregon.
26/27 April - The snow is finally receding and Mount St Helens is once again visible from the Volcanocams! There were a couple of short sharp tremors recorded on the VALT webicorder last night, most likely related to ice movement in the glacier.
25/26 April - While the weather forecast is for clear weather, both of the Volcanocam cameras remain completely blocked by a large snow bank! There were a couple of notable quakes registered on the webicorders last night (e.g. see VALT), but the largest were not associated with Mount St Helens, e.g. M2.2 nearby at Kalama and a M4.7 in Nevada.
24/25 April - Another cloudy night, with no views of Mount St Helens. Although the weather may clear a little over the weekend, before more snowy weather arrives next week. There were no notable seismic events overnight.
23/24 April - There was another larger tremor recorded on the webicorders last night at 22:23 PDT (05:24 UTC) which was not associated with MSH, but to a M4.0 quake off the coast of Oregon. The snow and cloudy weather continues to block the views of the crater. It is still not clear where the quake recorded yesterday was centred.
22/23 April - There appears to have been a larger quake at Mount St Helens at 04:37 EDT (11:37 UTC) this morning, it hasn't been picked up by the automatic network yet, but is visible in most of the MSH webicorders (e.g. VALT, HSR, SEP) and is also visible at a reduced size in a couple of the other webicorders at Mt Adams (ASR) and Rainer (RCM). There was nothing to be seen on the Volcanocam cameras as snow drifts continue to block the view.
21/22 April - The cloud and snow persist and there were no views of the crater overnight. Seismic activity remains low, with no notable events recorded in the last 24 hours.
18-21 April - Seismic activity has remained low over the weekend and there was only an occasional glimpses of the mountain from the Volcanocam cameras. The weather forecast is for continued snow, so it looks like it will be a little longer before Spring finally arrives on Mount St Helens!
17/18 April - The clouds and winter-like weather persists (what month is it?) and seismic activity remains low. Remember to check out the USGS/Cascades Volcano Observatory weekly update today on recent events at MSH. I will be without web access over the weekend, so updates won't resume until next Monday - have a great weekend all!
16/17 April - Another cloudy night, with no notable changes in the levels of seismicity. There may get a few glimpses of the crater today, before the stormy weather continues over the weekend :-(
15/16 April - More clouds, more snow and little to see at MSH over the last 24 hours. The M6.5 quake in the Aleutian Islands off Alaska is clearly seen on several of the webicorder traces from last night around 06:00 UTC. e.g VALT, HSR traces.
14/15 April - Clouds obscured all views of Mount St Helens last night, and believe it or not, but the snow is building up in front of the cameras again! Seismic activity has been low over the last 24 hours.
13/14 April - The clouds returned late yesterday and it is still shrouded from view. The VALT webicorder continued to show slightly elevated level of seismic activity last night, including what looked like a low-level period of tremor between 06:00 & 07:00 UTC, which was also visible (just) in the HSR trace.
12/13 April - The snow has receded and the view of Mount St Helens is clear again! Although further snow is predicted for the coming week, so the views we have today may not last long. Seismic activity remains low, although the activity monitored by the VALT webicorder in the crater shows some increase in activity, which isn't present on other webicorders around MSH - so whatever is causing it is quite local to that station.
11/12 April - The snow is finally in retreat and there are now partial views of the snow covered Mount St Helens crater on both the Volcanocam cameras! Seismic activity remains muted, although the VALT webicorder last night recorded a number of small tremors, probably related to movement in the glacier or small rock falls. The M5.2 quake off the coast of Oregon this morning is clearly visible on many of the webicorder traces. e.g. see HSR, VALT.
10/11 April - The snow remains buildup continues to block the view of MSH from the Volcanocam cameras, although warmer, sunnier weather is forecast for the next few days, so the snow's days may be numbered. Seismic activity remains low, with the occasional small tremor being recoded on the VALT webicorder. Also remember to check out the USGS/Cascades Volcano Observatory weekly update today on recent events at MSH.
09/10 April - There's still no views of Mount St Helens due to snow drifts in front of the cameras. Seismic activity continues to be minimal, with one notable tremblor at 08:05 UTC, corresponding to a M5.0 quake off the coast of Oregon. Note: The local time listed for the quake is 11:04pm PDT, yet the webicorder trace shows it occurring just after 01:04 PDT - it seems the webicorder may not be adjusted for daylight time. Regardless, the UTC time is correct.
08/09 April - Snow continues to block the view of Mount St Helens and seismic activity is low. The M7.5 quake near Vanuatu this morning is clearly visible on the VALT webicorder (the only MSH webicorder that appears to be providing useful information at present).
07/08 April - Slightly warmer temperatures and clearer weather is forecast to develop later in the week, so it is likely the snow buildup in front of the cameras will recede in the coming days. The VALT webicorder showed some small tremors overnight, but no significant increase in activity.
06/07 April - The snow continues to block all views from the Volcanocam cameras, so no new views of the crater today. Most of the MSH webicorders are showing large amounts of storm noise, but the VALT webicorder is still providing information on activity in the crater. Last night it showed a couple of small tremors, possibly the result of rock falls or movement of ice in the glacier.
05/06 April - Still no views of anything but snow and a few icicles on the Volcanocam cameras this morning. In fact the snow has built up to a greater extent than it was yesterday. Seismic activity is low and unchanged from recent days.
04/05 April - It seems that the snow drifts in front of the Volcanocam cameras are going to stick around for a little longer - so there's little chance of views of MSH in the short term unless the wind gets up and blows it all away!
03/04 April - The snow build up in front of the Volcanocam cameras has receded to cover about half the view, but this morning clouds and storms have moved back into the area and more snow is predicted for the coming days! The VALT webicorder shows the occasional small tremor typical of recent weeks, but no notable increases in seismic activity. Remember that the USGS/Cascades Volcano Observatory, will provide its weekly update today on recent events at MSH.
02/03 April - Seismic activity remains low as the snow banks in front of the Volcanocam cameras slowly recedes - the top of the crater is now visible above the snow on the HD Volcanocam...
01/02 April - There was a M5.2 quake off the coast of Oregon last night which appeared on many of the MSH webicorders, but local seismic activity remains low (e.g. see VALT webicorder trace). Snow accumulation in front of the Volcanocam cameras continues to obscure the view of Mount St Helens.
31 Mar/01 April - There's been little change from the last few days - the snow continues to block the views of Mount St Helens and seismic activity remains very low.
Note: All available movies of the nighttime activity of Mount St Helens, from 2004-2007 can be found in the archives.
