They estimate the volcano stopped 145 million years ago, give or take a few months.

Too bad, if that shield volcano has moved off the 'hot spot' like Mauna Loa almost has -- being done in maybe a half million years from now. Last eruption was 1984, I think?

Mauna Kea grew up from the ocean floor to about 31k feet in only a million years though. Last eruption was 3500 years ago.

I went to visit Halemaumau Crater last year. Gates of HELL. Fearsome and awesome to behold like I cannot describe as well as Mark Twain did. No kidding that when the Christian missionaries went to Hawaii to preach the gospel of the angry Judeo-Christian sky god, the Hawaiian natives said "Yeah, well, we have a fickle and ten times angrier volcano goddess named Pele that we can actually SEE." then they took the missionaries to Halemaumau Crater and watched them pee themselves.
