I Hope you're right, but there has been speculation that a large eruption of the Cumbre Vieja volcano on La Palma in the Canary Islands could cause a landslide dropping 1.6 *10^13 tons of rock into the 4 mile deep ocean; it seems that a 1949 eruption formed a huge crack right across the island that some people find extremely disturbing. If this were to happen it would produce a tsunami 1,000 metres (3,281 ft) high at the island but a few hours later after it traveled thousands of miles and reached the eastern seaboard of the USA it would only be about 50 metres (164 ft) high.
