Dear CurlyDave,

Not really. Less than 60 years ago (1958) there was a tsunami greater than 1400’ in Alaska.

See below from wikipedia:

“The 1958 Lituya Bay megatsunami occurred on July 9 at 10:15:58 p.m., following an earthquake with a moment magnitude of 7.8 and a maximum Mercalli Intensity of XI (Extreme). The earthquake took place on the Fairweather Fault and triggered a rockslide of 30 million cubic metres (40 million cubic yards, and about 90 million tons) to fall from several hundred metres into the narrow inlet of Lituya Bay, Alaska. The impact was heard 50 miles (80 km) away,[6] and the sudden displacement of water resulted in a megatsunami that destroyed vegetation up to 1,722 feet (525 m) above the height of the bay and a wave that traveled across the bay with a crest reported by witnesses to be on the order of 98 feet (30 m) in height.[citation needed] This is the most significant megatsunami and the largest known in modern times. The event forced a re-evaluation of large wave events, and recognition of impact, rockfall and landslide events as a previously unknown cause of very large waves.”

Cheers! I admit, however, that it was probably the geography involved that resulted in this megatsunami and that would be unlikely in your area.

There you go, those bays focus the tsumami most excellently.

Had that here on the Big Island in the 2011 tsunami from the Fukushima quake. Most of the coast had little but surge. Keauhou bay got the royal flush.

Other bays got various amounts of excessive damage including a house washed into the bay, but all in enclosed areas.
