Happy 10th birthday to the NASA Earth Observatory, which has been bringing us wonderful images of the Earth from space since 29 April 1999. Congratulations and many happy returns to the Earth Observatory and to all the hard-working people behind the scenes who have made it such a marvellous web resource for the last decade.

The voting for the ten favourite images of the day from the last ten years is now complete, and the winners are available for viewing here: Top 10 Images of the Day. Not a volcano among them, sadly, so to make up for that here’s a favourite of mine:

That unusual and always interesting corner of the web Environmental Graffiti (‘an eclectic mix of the most bizarre, funny and interesting environmental news on the planet’) has a long-standing and thoroughly admirable interest in volcanoes.

Their latest article of volcanic interest, ‘Anything for the perfect volcano shot!’ by Karl Fabricius, talks to Dr Tom Pfeiffer of VolcanoDiscovery about the excitements and dangers of volcano-visiting, and includes some stunning photographs from the heart of the action in Hawaii.

Zooming in on Redoubt 20 April 2009

A beautiful clear day on Cook Inlet today, and some wonderful views on the various webcams that the Alaska Volcano Observatory has trained on Mount Redoubt. The zooming in of the Hut Webcam on the area of the extruding lava dome is particularly stunning. The dark mass in the upper middle of the image is the lava dome, looking sinister as lava domes always do:

The more conventional Hut Webcam view is also beautiful today:

The DFR Webcam is giving a lovely crystal-clear image:

And finally the Cook Inlet camera gives a nice wide vista of the erupting volcano:

The news from Redoubt is not itself dramatic. The eruption is continuing, the lava dome is building, there is a thermal anomaly at the dome and a continuous, low but vigorous steam plume.

Chaitén dome and pinnacle from the north-west 8 April 2009

A little while ago we published some beautiful pictures of Chaitén’s lava dome and pinnacle, viewed from Chaitén town, taken by Nicolas La Penna of Chaitur.com on 17 March this year. Nicolas has very kindly sent in two more pictures which are of particular interest because they show the northern side of the volcano, which is an aspect we see far less often than the southern side that faces the town.

The pictures were taken on 16 March 2009 from a position north-west of the lava dome. The sheer wall of the pinnacle, wreathed in steam, is very evident in these pictures.

Thanks to Nicolas La Penna of Chaitur.com for these pictures.

The Boston Globe has some stunning, and varied, images of Redoubt’s current eruptive activity in its ‘Big Picture’ feature. Lots of wonderful volcano pictures to feast your eyes upon: Alaska’s Mount Redoubt – The Big Picture.

Llaima 4 April 2009, 18:31 (POVI)

The dedicated Llaima-watchers at POVI, Proyecto Observación Visual Volcán Llaima, have compiled a time-lapse video of the eruption of Llaima on 4 April 2009. The three-minute video compresses images from around 17:27 to 20:10 local time, captured by their webcam pointed at the volcano’s summit, and shows some spectacular fire-fountaining both in daylight and in the dark (see images above and below).

The POVI video can be viewed at YouTube.

The Alaska Volcano Observatory has released aerial video footage taken during helicopter-supported fieldwork at Redoubt on 23 March 2009. The footage clearly shows the huge mudflows that have choked the Drift Valley, ashfall on the surrounding landscape, steam rising from meltwater channels, and the thickness of some of the mud deposits. The video is available to download as a 14min 33 sec 210MB .wmv file – for details, follow this link to the AVO website. Below are some screen captures from the video (credit: Kristi Wallace – AVO/USGS).

AVO Redoubt Hut webcam, 23 March 2009 20-01-23

Redoubt-watchers will be aware that the Alaska Volcano Observatory’s Hut webcam went offline during the eruption yesterday, but came back again towards the end of the afternoon. As a result images were captured of the eruptive activity – the sixth explosive event – that took place from 19:41 local time onwards yesterday.

From these webcam images Akira Shirakawa has compiled a video, with synchronized sound, that shows activity between 19:19 and 20:43, available at YouTube. Large-scale ash emission makes everything very dark around 19:50 (at video time 0:24), and a big ash eruption can be clearly seen at 20:01 (video time 0:34).

There is also a page of Hut webcam images and a time-lapse movie here (h/t Chris Rowan, via comment at Eruptions).

A generous reader of The Volcanism Blog has also submitted these video captures (available at this Flickr page) from the webcam, taken between 19:50 and 20:43 on 23 March. The image from 20:01 is at the top of this post, to see all eight images in sequence click on ‘more’.
