Scientists discover big ‘stormquakes’
Scientists have discovered a mash-up of two feared disasters — hurricanes and earthquakes — and they’re calling them “stormquakes.”
The shaking of the sea floor during hurricanes and nor’easters can rumble like a magnitude 3.5 earthquake and can last for days, according to a study in this week’s journal Geophysical Research Letters. The quakes are fairly common, but they weren’t noticed before because they were considered seismic background noise.
