An earthquake of magnitude 7.5 in Alaska prompted a tsunami warning on Monday, AP reported. The warning, however, was downgraded to an advisory just over two hours after the quake hit.
The quake was centered near Sand Point, a city of about 900 people off the Alaska Peninsula where wave levels topped two feet, according to the National Tsunami Warning Center. The quake was recorded at a depth of 30 kilometers.
The quake was felt widely in communities along the southern coast, including Sand Point, Chignik, Unalaska and the Kenai Peninsula. The Alaska Earthquake Center said a magnitude 5.2 aftershock was reported 11 minutes later, centered roughly in the same area.
The National Tsunami Warning Center in Palmer, Alaska, said the tsunami warning was in effect for roughly 1,529 kilometers, from 64 kilometers southeast of Homer to Unimak Pass, about 129 km northeast of Unalaska.
Scott Langley from the National Tsunami Warning Center said the earthquake sent two waves, each measuring 130 centimeters (4 feet, 3 inches) high, according to CNN. But observers onshore reported the waves appeared to be 1.5 feet (45.7 centimeters) and 2 feet (61 cm) over high tide.
