Resumen de Ice melt blamed for Greenland's fake quake
Earthquakes in Greenland are rare. At least, they're supposed to be. So it was a surprise when a magnitude 4.1 "quake" struck Nuugaatslaq, a tiny island off Greenland's west coast on 17 June. It triggered a tsunami that smashed homes, leaving at least four people dead. But what residents--and seismic equipment--initially labeled as a quake may be nothing of the sort. Glaciologist Martin Luethi thinks the culprit was a landslide at nearby Karrat fjord. As the falling mountain hit the ocean, it created enough seismic noise to dupe sensors and generate the waves that inundated Nuugaatslaq. He blames melting ice for destabilizing the rock below.
