At 8.37am on Wednesday, an enormous section of a glacier in the Himalayas sheared free and crashed on to the valley floor in Nepal’s Langtang national park, about 35 miles (60km) north of the capital, Kathmandu, near the mountainous Nepal-Tibet border.
Such was the force of the event, it was initially reported as an earthquake of magnitude 4.4. The US Geological Survey later determined the tremor was caused by glacial rock and ice collapsing, registering a magnitude of 5.2.
