Of 2.4 miles, triggered by an earthquake triggered a giant wave that destroyed a native village and drowned people! In June 2016, pilot Paul Swanstrom followed a strange dust plume and found the aftermath of a more than 100-million-ton slide onto the Lamplugh Glacier. The Tyndall Glacier slide appears to have been triggered by the passing seismic waves of a distant magnitude 4 earthquake, but that was only the tiniest nudge, imperceptible to a person. [10] The two arms that create the top of the T-shape of the bay are the Gilbert and Crillon inlets and are a part of a trench on the Fairweather Fault. On July 9, 1958, the largest wave in modern history occurred in Lituya Bay, on the northern Southeast Alaska coast about halfway between Cape Spencer and Yakutat. Two of the boats, the Badger and the Sunmore, were anchored just inside the mouth of the bay, behind a low spit that separates it from the ocean. Anchored in a cove near the west side of the entrance of the bay, Bill and Vivian Swanson were on their boat fishing when the earthquake hit:[10], With the first jolt, I tumbled out of the bunk and looked toward the head of the bay where all the noise was coming from. They felt the quake and watched as an 800-foot stretch of the island's beach disappeared into the bay along with three of their friends. A M4.9 Jolt in Interior Alaska. This landslide caused 30 million cubic meters of rock to fall into the bay, creating the megatsunami. Swanson also claimed to be able to see Lituya Glacier, normally hidden behind the turn the T-shaped bay takes to the northwest. The Landslide Blog (2008, July 9) Lituya Bay50 Years On. July 9, 1958: Regarded as the largest recorded in modern times, the tsunami in Lituya Bay, Alaska was caused by a landslide triggered by an 8.3 magnitude earthquake. Instead, the megatsunami was caused by a massive and sudden impulsive impact when about 40 million cubic yards of rock several hundred meters above the bay was fractured from the side of the bay, by the earthquake, and fell "practically as a monolithic unit" down the almost vertical slope and into the bay. This earthquake had been the strongest in over 50 years for this region: the Cape Yakataga earthquake, with an estimated magnitude of 8.2 on the Richter scale, occurred on September 4, 1899. Miller could not explain how the earthquake had caused such an enormous wave, but he was certain that it had. (Image: Geology.com/NASA Landsat) Detailed Description. This sudden displacement of the water in the bay resulted in a mega tsunami which was so intense that the . Along the Fairweather Fault in southeast Alaska, an earthquake in Alaska, killed 159,. After a while, the glacier fell back out of sight. But a record-breaking tsunami of a different sort occurred in 1958, in a remote part of Alaska known as Lituya Bay and was witnessed by only six people, two of whom died. A little after midnight, a boat responding to Ulrich's mayday calls found and rescued the Swansons. North shore of Lituya Bay in 1953, showing wave trimlines from previous tsunamis in 1853-54 and 1936. Credit: U.S. Geological Survey.

Tonight's M4.9 earthquake at 9:56pm rattled the Interior, with felt reports from Fairbanks, North Pole, Salcha, Nenana, Healy, Cantwell, Delta Junction, Chugiak, Anchorage, and as far south as Victoria, British Columbia. The strongest tsunamis occur in the open ocean, moving at the speed of jet aircraft and reaching the size of a skyscraper. The front of Lituya Glacier is at the lower left corner. The impact was heard 80 kilometers (50mi) away,[7] and the sudden displacement of water resulted in a megatsunami that washed out trees to a maximum elevation of 524 meters (1,719 feet) at the entrance of Gilbert Inlet. The strike-slip earthquake took place on the Fairweather Fault and triggered a rockslide of 40 million cubic yards into the narrow inlet of Lituya Bay, Alaska. Miller was not around to study these, as he had drowned on the Kiagna River with a young assistant in 1961. The glacier had risen in the air and moved forward so it was in sight. Sunmore. The epicenter was 8 miles east of Salcha, with a depth of 2.4 miles. The lighthouse at Harbor Point and the cabin on Cenotaph Island were both gone without a trace. The tide was ebbing at about plus 1.5 m and the weather was clear. The northeast wall of Gilbert Inlet in August 1958 shows the scar of the rockslide that generated the megatsunami. It was felt from Seattle to Whitehorse, though most of the structural damage was confined to Yakutat. This proposed another possible cause to the production of the 100ft (30m) wave which caused destruction as high as 1,720ft (520m) above the surface of the bay as its momentum carried it upslope. That was six miles away and they still looked like big chunks. But Miller had seen driftwood and rocks strewn across the slopes at the top of the trimline, and the trees that had not been washed into the bay all lay on the ground pointing westward, as the wave had traveled.
