The death toll from catastrophic flooding in Nepal and China passed has 1,000 as rescue teams worked to reach communities cut off by the disaster. Nepal’s disaster agency said Tuesday that 987 deaths had been counted there, with 3,916 people missing, including 583 foreigners. Chinese authorities reported 16 deaths in their most recent update on Sunday. The Aug. 26 disaster began with a chain of events high in the Himalayas. A glacial collapse sent large amounts of rock, ice and meltwater into valleys below, triggering powerful floods downstream. Scientists studying satellite imagery said the collapse appears to have involved the failure of bedrock beneath a glacier in the Himalayan region. The rockfall was powerful enough to register as a magnitude 5.2 seismic event.
