The great Himalayan mountain chain and the vast summer monsoon that drenches it in rain each year combine to make northernmost India a deadly as well as dramatic region. Landslides come with the territory, but this year has brought catastrophe as the monsoon came early and heavy. Landslides began about three weeks ago, swamping numerous mountain towns, and rescue efforts have been slow. As a result, news has come in a trickle. Geoscientist David Petley, a landslide expert, has been gathering news reports and satellite imagery on his Landslide blog, sponsored by the American Geophysical Union. Today he reports that the authorities are about to declare some 4000 victims officially dead, and the death toll may well exceed 10,000. For news both human and scientific, his blog is landslide central. Catch up with developments in the area on Petley's landslide report archives.
