Inflation of Mauna Loa says only a matter of time

Tsunamis are caused by earthquakes. We have had earthquakes in our neighborhood (Pacific rim/ring of fire) lately but by chance they have not caused tsunamis. So we are not statistically overdue for the causative events for tsunamis. It has just been chance that recent earthquakes did not cause the type of displacement that results in tsunamis.

An earthquake that can justifiably be considered a destructive whopper to us occupants of high-rise buildings on land might only cause sideways displacement of the the ocean floor (no tsunami) or it might just as easily cause a vertical displacement (big tsunami).
