Shake your berg thing

TasmanNASAbergs

This astonishing view of the Tasman Glacier from space, captured by NASA’s Terra satellite on March 2nd, shows the bergs in the glacial lake — the remnants of the 30 million tons of ice that broke off during the Christchurch earthquake on Feb 22nd. It’s a false colour image — red means vegetation, and the grey-browns are bare rock (and the rock debris covering the glacier itself). There’s more information at the NASA Earth Observatory. The Tasman’s near neighbour the Murchison Glacier has recently featured at Mauri Pelto’s From A Glacier’s Perspective. Both are retreating strongly.

[Update 9/3: The Earth Observatory’s latest image of the day is a stunning satellite picture of the Christchurch region, with an overlay showing shaking intensities.]

Nice find on the NASA image. If you examine the full image it indicates no calving event from the earthquake for Hooker or Murchison Glacier . I added the NASA closeup image of the terminus of the Murchison to the post.

The full image (covers the whole Mt Cook region) is breathtaking — well worth a 3MB download.
