Argentina Town Braces for Glacial Flood Disaster
22 Sep
Summary
- El Chaltén faces a catastrophic glacial lake flood risk.
- A landslide into Laguna Torre could trigger a 20-minute deluge.
- An early-warning system is being developed to aid preparedness.
The town of El Chaltén in Argentina's Santa Cruz province is facing a severe risk of a catastrophic glacial lake outburst flood (Glof). Geologist Daniela Schmidt's research indicates that a landslide into Laguna Torre could unleash a devastating flood within 20 minutes. This scenario, amplified by recent glacial flood disasters in Nepal, has spurred urgent preparedness efforts.
Authorities are working to establish Argentina's first Glof early-warning system and evacuation plans. The retreat of the Torre glacier has destabilized surrounding slopes, increasing the likelihood of rockfalls into Laguna Torre. Such an event could generate a massive wave, inundating critical infrastructure like the town's only access bridge.
Community leaders are balancing the urgency of disaster preparedness with concerns about the impact on tourism, a vital economic sector. Despite funding challenges, efforts are underway to install monitoring stations and develop alert systems. Residents are being educated about the risks, fostering a more resilient and aware community prepared for changing glacial landscapes.
