Within the last 24 hours, 2 rare earthquakes have rattled the USA.

A 3.7-magnitude tremor was recorded off northwest Florida, while a M4.1 quake shook the region of Shishmaref in Alaska, an area almost unknown to shakings.

On July 16, 2016, two extremely rare earthquakes rattled unexpectedly seismically unactive areas in the USA: Off Daytona Beach Shores, Florida and Shishmaref, Alaska.

The rare 3.7 magnitude earthquake was reported off Florida’s Atlantic coast just over 100 miles east of Palm Coast on Saturday, July 16, 2016 at 4pm.

No residents have reported feeling the minor earthquake. And this would have been another rarity! Florida has felt the effects of only around two dozen seismic events and one of the last earthquakes to cause damage happened back in 1879.

On July 9, 2016, Shishmaref was hit by the strongest earthquake (M4.8) in its history. During the week-end, the area was hit by a M4.1, the second strongest quake (ex-aequo: M4.1 on 9.11.2004 and 08.11.1974) in the region. Fracking, army tests. What is going on?

Meanwhile two other earthquakes shook 8km SW of Caruthersville, Missouri and 1km SSW of Beaverton, Oregon.

These earthquakes striking unexpected places are kind of worrying.
