US authorities have cancelled a tsunami warning for 121 kilometers (75 miles) south of Chignik, Alaska.
"The tsunami warning for the 7.8 magnitude Alaska earthquake has been cancelled," the US National Weather Service said on Twitter, following a quake 99 km (62 mi) from Perryville, Alaska.
The hour-long warning had included parts of coastal Alaska from the Kennedy Entrance to the Umiak Pass.
On the morning of March 28, 1964, without warning, the largest recorded earthquake in US history struck Alaska’s Prince William Sound. The 9.2 magnitude earthquake and subsequent tsunamis took over 139 lives, according to US National Centers for Environmental Information.
The earthquake and ensuing tsunamis caused about $2.3 billion of damage (equivalent to $311 million in 1964). The greatest damage was sustained, not from the earthquake itself, but from soil failure, tsunamis, landslides, and avalanches.
