All are welcome
On October 17th 2015, a massive landslide at the terminus of the rapidly retreating Tyndall Glacier in Southeast Alaska sent over 50 million cubic meters of rock into Taan Fiord. The resulting tsunami reached elevations as high as 193 m and scoured vegetation kilometers from the source. Field and remote sensing investigations following the event, presented here, reveal low-lying fan deltas that may preserve geomorphic evidence of the tsunami for decades to centuries.
