Interesting story. It looks like the center of the earthquake is north of the Loihi seamount where there's a hotspot in the lower Earth and our plate is moving over the hot spot to the northwest. 

The report says that the crust is bending but if it were to slip due to a fault then Hilo would be vulnerable to another huge tsunami wave. 

Also don't understand why the crust is bending there. Most of the outflow from Kilauea is weighing the island towards the loihi side of the island. Are we building up to an event much like the event that created the windward cliffs on the Koolau range on Oahu?
