The effect of the tsunami still visible in 2010. Differently-aged vegetation visible on the ridge separating Lituya Glacier from the main part of the bay - looking north from the head of the bay, Lituya Glacier to the right. The event at Lituya Bay still stands as one of the tallest tsunami waves known to science. The photo above, taken in 1958 after the tsunami, shows the ring of damage around much of the bay. Evidence of the cataclysmic wave is still visible from space more than 60 years later.

More forgotten is the tragic 1958 Lituya Bay earthquake and its accompanying megatsunami. Lituya Bay locator map Lituya Bay is a seven-mile long, two-mile wide fjord on the southeast. On July 10, 1958, a magnitude 7.7 earthquake occurred on the Fairweather Fault in southeast Alaska. It caused significant geologic changes in the region, including areas that experienced uplift and subsidence. It also caused a rockfall in Lituya Bay that generated a wave with a maximum height of 1,720 feet - the world's largest recorded. A megatsunami is a tsunami with an initial wave amplitude ( height) measured in many tens or hundreds of metres. A megatsunami is a separate class of event from an ordinary tsunami and is caused by different physical mechanisms. Normal tsunamis result from displacement of the sea floor due to plate tectonics. The 1958 Lituya Bay landslide-generated mega-tsunami is simulated using the Landslide-HySEA model, a recently developed finite-volume Savage-Hutter shallow water coupled numerical model.

The recent disaster in Japan demonstrates the incredible destructive power of a megatsunami in a heavily populated area. 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. The mega-tsunami runup to an elevation of 524 m caused total forest destruction and erosion down to bedrock on a spur ridge in direct prolongation of the slide axis. A cross section of Gilbert Inlet was rebuilt at 1:675 scale in a two-dimensional physical laboratory model based on the generalized Froude similarity.

OCEAN GOVERNANCE [1] The largest mega-tsunami dates back half a century to 10 July 1958, when almost unnoticed by the general public, an earthquake of M w 8.3 at the Fairweather Fault triggered a rockslide into Lituya Bay. The rockslide impact generated a giant tsunami at the head of Lituya Bay resulting in an unprecedented tsunami runup of 524 m on a spur ridge in direct prolongation of the slide axis.
