7.9-Magnitude Earthquake Causes Ripple Effect
The 7.9-magnitude Alaska earthquake last week had a ripple effect as far as Florida, according to the Miami Herald. “Within an hour after the quake hit at 4:32 a.m. eastern time, groundwater 3,500 miles away in Fort Lauderdale dropped by an inch and a half. Up the coast in the state’s Big Bend, it rose two inches in wells monitored in Madison, according to the U.S. Geological Survey [USGS],” the paper reported.
Officials for the USGS said that the Alaska tremor caused fluctuations. “Think of it as the ripples in a glass of water on a table when a truck drives by outside,” they said, reported the Herald.
Water levels, officials said, returned to normal within a few minutes.
