as the surface-wave magnitude was very low compared to the moment and tsunami magnitudes, and the tsunami height was far larger than expected for the surface wave magnitude. The very high tsunami magnitude value is due to the sheer strength of the waves. It was calculated by using tsunami run up from

The tsunami was unusually powerful for the size of the earthquake. The event was classified as a tsunami earthquake due to the discrepancy between the size of the tsunami and the relatively low surface-wave magnitude. The large-scale destruction prompted the creation of the

as well. Waves there demolished 77 homes and many other buildings. The residents of these islands were caught off-guard by the onset of the tsunami due to the inability to transmit warnings from the destroyed posts at Scotch Cap, and the tsunami is known as the April Fools' Day
Tsunami in Hawaii

At Unimak Island, tsunami run-up reached 42 m (138 ft). The tsunami earthquake aspect of this event helps to explain a portion of this massive height; however, the rest must be attributed to a local submarine landslide. Waves reportedly traveled across the ocean at 500 miles per hour

The earthquake struck at 02:29 local time on April 1, 1946, at a shallow depth of 15 km (9.3 mi). The earthquake was very large, but the maximum felt intensity was only a VI. The earthquake was originally thought to be a rather smaller earthquake of
