While the eruption of 2018 had the island shaking, 2019 has had seemingly few felt earthquakes. I have gone several months without feeling a quake.

It was something of a surprise when the house rattled this morning just before 6am.

Deb asked me, “Was that a quake?”

“Yes.”

From the short, sharp rattle I guessed it was close… I was right, a magnitude 3.1 in North Kohala. It was also deep, a bit over 14 miles down. This was a classic settling quake as the weight of the island presses into the ocean crust.

On a Saturday morning we did not stay awake for long, cats included.

Update: The quake was later upgraded to a 3.4 after review by the USGS.
