It has been a tremendous privilege to be part of a 68-strong international cross-disciplinary team of scientists trying to solve the puzzle of a #seismic signal that was observed around the globe for nine days. A massive #rockslide into a #Greenland #fjord generated a #tsunami with 200 meter run-up that coalesced into a long duration seiche. Our findings are published in the journal Science this evening.

Oh, super. New and mysterious consequences of #ClimateChange :

"A rumble echoed around the world for nine days. Here’s what caused it.

It took about 70 people from 15 different countries and more than 8,000 exchanged messages to crack the case."

Experts working with the #FirstNation of #NaChoNyäkDun who have witnessed the fallout at #VictoriaGoldEagle mine near #Mayo, #Yukon, say systems on-site are so severely compromised that damage to the land & water is all but inevitable.

What they describe is a system rendered mostly #inoperable, with each affected piece elevating #risks to the #environment — every day.

On June 24, part of the Eagle #mine failed and a massive #RockSlide involving roughly 4 million tonnes of material cleaved off a large piece of the facility where #gold is extracted from ore using a chemical process called cyanide heap leach. Estimates put the amount of ore stacked on the heap leach pad — which functions as a giant industrial percolator — at nearly 4 times what was lost in the slide.

With the #HeapLeach pad downed, experts say a #toxic soup of #SodiumCyanide & other #contaminants — up to 300,000 cubic metres of solution, according to the #YukonGovernment — was released in the initial slide. Since then, they say, more of it has been draining.

The First Nation of Na-Cho Nyäk Dun has called the event "the region's most recent and potentially #catastrophic #mining failure."
