On April 1, 1946, an undersea earthquake off the Alaskan coast triggers a massive tsunami that kills 159 people in Hawaii.
In the middle of the night, 13,000 feet beneath the ocean surface, a 8.6-magnitude tremor was recorded in the North Pacific. (The nearest land was Unimak Island, part of the Aleutian chain.) The quake triggered devastating tidal waves throughout the Pacific, particularly in Hawaii.

Tsunami warnings were lifted for parts of Alaska after a monster of an earthquake rocked its peninsula early Thursday.
The magnitude 8.2 quake struck off Alaska’s Aleutian Islands chain, which prompted immediate tsunami warnings and evacuations in Kodiak.
According to NBC News, tsunami warnings for parts of Alaska were later lifted. A tsunami watch was also canceled for Hawaii.
On April 1, 1946, an undersea earthquake off the Alaskan coast triggers a massive tsunami that kills 159 people in Hawaii.
In the middle of the night, 13,000 feet beneath the ocean surface, a 7.4-magnitude tremor was recorded in the North Pacific. (The nearest land was Unimak Island, part of the Aleutian chain.) The quake triggered devastating tidal waves throughout the Pacific, particularly in Hawaii.

On this day in 1946, an undersea earthquake off the Alaskan coast triggers a massive tsunami that kills 159 people in Hawaii.
In the middle of the night, 13,000 feet beneath the ocean surface, a 7.4-magnitude tremor was recorded in the North Pacific. (The nearest land was Unimak Island, part of the Aleutian chain.) The quake triggered devastating tidal waves throughout the Pacific, particularly in Hawaii.
Unimak Island was hit by the tsunami shortly after the quake. An enormous wave estimated at nearly 100 feet high crashed onto the shore. A lighthouse located 30 feet above sea level, where five people lived, was smashed to pieces by the wave; all five were killed instantly. Meanwhile, the wave was heading toward the southern Pacific at 500 miles per hour.

Shaking from the large earthquake that shuddered through Anchorage, Alaska last week was strong enough to turn smooth asphalt roads into broken, jagged depressions of rubble. But within just a few days, crews managed to repair the worst of the damage, unsnarling traffic in Alaska’s largest city.
Anchorage has a population of nearly 300,000 people spread across more than 1,900 square miles — an area larger than the state of Rhode Island. That space is threaded by roads, asphalt lifelines of the population. When the magnitude 7.0 earthquake struck last week, some of the most visceral images showed roads that had broken apart. But within days, many of these same cracked highways had been smoothed back into ribbons of pavement by crews working around the clock.
