A lightly populated stretch of Alaska ’s southern coast was under a tsunami warning Wednesday after a strong earthquake was felt throughout the region, and officials in the Pacific Northwest were evaluating whether there was any threat to coastlines there. Early measurements put the quake’s magnitude at 7.3.

Calling it an exercise in imagination, seismologist Carl Tape stopped at the site of Dome City and the former townsite of Meehan 113 years after a 7.2 magnitude earthquake struck the area.
