Massive 7.9 Quake Off Alaska This Week
The magnitude 7.9 earthquake off the coast of Alaska earlier this week initially sparked fears that a massive tsunami was set to follow.
While the alert was quickly dropped, startling new data shows just how powerful the seismic blast truly was.
The US Geological Survey has revealed that two of its wells in Florida detected changes caused by the earthquake, despite being roughly 3,800 miles from the epicentre.

In wells near Ft. Lauderdale and at Blue Springs, near Madison, the USGS found that water levels changed dramatically after the quake.
At Blue Springs, levels jumped from about 41.59 feet to 41.77.
And, the opposite happened in Ft. Lauderdale – there, the experts noted a drop from around 1.42 feet to just over 1.3.
‘Alaska’s magnitude 7.9 earthquake rattled Earth’s plumbing 3,800 miles away in Florida, where water levels in 2 wells spiked within minutes,’ USGS tweeted after the quake.
It might seem extreme, but according to the experts, this type of activity is common following powerful earthquakes.
