Unusual set of earthquakes near Mauna Kea Summit

Starting with a 4.5 magnitude, in the past two hours there have been over 23 earthquakes in a tight cluster located about six miles west-northwest of the summit of Mauna Kea. The depth of these quakes seems to average about 12 miles.
So far, besides the 4.5 there has been a couple over magnitude 3.0, with most around 2.3 or so (see complete list below). One small quake was very near Mauna Kea summit itself. 530 people reported feeling the 4.5
Mauna Kea is categorized as a dormant volcano, having last erupted about 4,500 years ago. However, Mauna Kea is likely to erupt again someday.

Also, perhaps unrelated, there was a short sharp drop on the deformation tilt graph monitior for Kilauea (upper right corner) that at a glance looks to be closely timed to the current quakes, though it is hard to be precise without a closer timeline.

You can keep track of these quakes and any new ones on the Hawaii Island Earthquake Map HERE.
