Why does Hawaii have earthquakes if it is not near a plate boundary?

The Hawaiian Islands experience thousands of earthquakes each year, despite being far from an active tectonic plate boundary. The majority of these earthquakes in the shallow crust can be explained by the rapid seaward slip of the moving southern flanks (see Figure 2).

How is Hawaii’s seismic density calculated?

We calculate earthquake density by dividing the total number of earthquakes in a state by the area of ​​the state and normalize the numbers so that the earthquake density in Hawaii is 100 for convenience. Seismic density tells you how many earthquakes there are in each state per area (eg, 1 acre).
