00:00A strong earthquake just hit Alaska's coastline.
00:03But here's why no one's panicking.
00:05On September 3rd at 1 p.m., a magnitude 6 earthquake shook the waters near Nikolsky, Alaska.
00:11But despite the seismic jolt, there's good news.
00:13There's no tsunami threat.
00:15The U.S. Geological Survey says the quake was significant, but not dangerous to local communities.
00:21Nikolsky is 87 miles from the epicenter, and thanks to its offshore location,
00:25the tremor caused little to no visible damage.
00:29Alaska, sitting on the Pacific Ring of Fire, is used to these quakes.
00:33And according to the USGS, this one didn't meet the conditions needed to spark a tsunami.
00:38Why?
00:39Because tsunamis need stronger quakes, usually over 7.6, and a major deformation of the seafloor.
00:45This one didn't come close.
00:47Even rare underwater landslides didn't follow.
00:50Thanks to real-time assessments by USGS and NOAA, locals stayed calm.
00:54No aftershocks, no secondary threats, just another rumble in an already active zone.
01:00Alaska's preparedness made the difference.
01:02And while the ground may shake again, today it was just a reminder, not a disaster.
01:08The U.S. Geological Survey
