Earthquakes in Greenland are rare. At least, they’re supposed to be. But a few weeks ago, a 4.1 “quake” struck Nuugaatsiaq, a tiny island off Greenland’s west coast, triggering a massive tsunami that smashed homes, leaving at least four people dead.
One brave but panicked Greenlander recorded that 17 June incident on a shaky iPhone.
But what residents – and seismic equipment – initially labelled a quake may be nothing of the sort.
“Everyone was fooled by the collapse of a mountain,” says Martin Luethi, a Swiss glaciologist who has been studying Greenland’s glaciers since 1995. “The tsunami wasn’t triggered by an earthquake.”
