Original story

A tsunami warning was issued for southern Alaska and the Alaska Peninsula after a massive 7.8-magnitude earthquake struck the state Tuesday, July 21.

According to the United States Geological Survey, the quake struck at a depth of six miles and was centered 60 miles south-southeast of Perryville, Alaska. This prompted a tsunami warning for southern Alaska and the Alaska Peninsula.

"If you are in a tsunami warning area, evacuate inland or to higher ground above and beyond designated tsunami hazard zones or move to an upper floor of a multi-story building depending on your situation. Move out of the water, off the beach, and away from harbors, marinas, breakwaters, bays and inlets. Be alert to and follow instructions from your local emergency officials because they may have more detailed of specific information for your location," the alert reads.

Several people shared their experience in the comments section of earthquake-tracking website EMSC-CSEM.

"Bed and curtains were going. Felt like a very long quake! Felt at Homer, Ak at the end of the Spit at Lands End," one wrote. "Felt very dizzy," wrote another.

Reports stated that the quake was also felt in Anchorage, Alaska’s largest city.
