Maui has an excellent tsunami warning system. If there was a danger, they'd be hearing sirens.
Lessons learned from the tsunami that wiped out HIlo in 1960, I think is was. The city was rebuilt 5 miles inland..
USGS moved the location a bit further south - to the West Flank of Mauna Loa - the most common location for large quakes on the Big Island.
Is there any chance
a wave could propagate east
and wash the debris
from Los Angeles
and San Francisco? That would
start the week off well . . .
