SAN FRANCISCO, July 16 (Xinhua) -- A 7.2-magnitude earthquake off the U.S. Alaska Peninsula on Saturday night triggered a tsunami advisory.
The earthquake struck about 98 km south of Sand Point with a depth of 32.6 km at 10:48 p.m. local time (0648 GMT on Sunday), the U.S. Geological Survey said.
The advisory is in effect for coastal Alaska from Chignik Bay to Unimak Pass, according to the U.S. Tsunami Warning Center.
The National Weather Service said strong currents or waves are expected where a tsunami advisory is in effect.
The tsunami advisory was downgraded from an initial warning for a broad swath of Alaska's coastline from the eastern Aleutians to the mouth of Cook Inlet in the aftermath of the strong quake.
According to the U.S. Geological Survey, the earthquake's magnitude was also revised from 7.4 to 7.2.
There were no immediate reports of damage or injuries. ■
