A massive landslide on B.C.'s remote central coast in 2020 triggered a lake tsunami over 100 metres tall, according to a new paper published by researchers from the University of Northern British Columbia. Described as a rare "hazard cascade," the tsunami then sent a vast torrent of water or "outburst flood" into Elliot Creek, uprooting trees, soil and rock as it surged down the valley. The slurry was in turn propelled into the Southgate River and then Bute Inlet, leaving a devastated landscape in its wake.
