It has been very hot this month. Figger that is what dun it.
Looks like the heat also melted down Climate Progress.
The 1946 Pacific tsunami caused damage all the way to Chile. It was a lot shallower earthquake. If my thinkolator isn’t on the blink I remember a deep quake like that before Sarychev Peak in the Kurils exploded in 2009. I hope we don’t have magma cracking rock again.
The 1946 Aleutian Islands earthquake was an earthquake near the Aleutian Islands on April 1, 1946. It was followed by a Pacific-wide tsunami. The earthquake was a magnitude 7.8, with its epicenter at 52.8°N, 163.5°W, and focal depth of 25 km. It resulted in 165 casualties (159 people on Hawaii and six in Alaska) and over $26 million in damages.
Multiple destructive waves at heights ranging from 45 –130 ft occurred. It obliterated the Scotch Cap Lighthouse on Unimak Island, Alaska. among others, and killed all five lighthouse keepers. The wave reached Kauai 4.5 hours after the quake, and Hilo 4.9 hours later. This prompted the creation of the Seismic Sea Wave Warning System, which later became the Pacific Tsunami Warning Center in 1949. [1]
The tsunami was unusually powerful for the size of the earthquake; it was the last time any earthquake below magnitude 9.0 caused tsunami fatalities far from the earthquake area. Scientists think the tsunami may have been caused by an earthquake triggering an underwater landslide.

Sorry, I can’t make out any shaking of the buildings because the camera is shaking too much.
