The system has issued timely alerts over the past several years, effectively preventing casualties.But on Wednesday, a high-altitude ice-rock avalanche took everyone by surprise. The debris flow hit a river in Nepal, generating a devastating flash flood that swept all the way down to Gyirong county in the Tibet autonomous region in China.Some specialists say the disaster was triggered by glacial rock collapse.04:12Timeline of the China-Nepal border disasterIt remains unclear whether the China-Nepal early warning system had detected an anomaly before this disaster or issued an alert. But coincidentally, a paper published on Wednesday by the project team highlighted several of China’s recent successes.
