The US Geological Survey’s Hawaiian Volcano Observatory upgraded the magnitude of this morning’s Kīlauea earthquake to a 4.3.

Agency officials say they received more than 80 responses within two hours of individuals saying they felt the quake with “weak shaking” reported.

As of 10 a.m., the USGS reported five aftershocks from the quake, the strongest of which was a magnitude 1.

According to an agency press release, “Today’s earthquake could lie on the fault that marks the boundary between Mauna Loa and Kīlauea, or it could have occurred on a reactivated fault within the old oceanic crust upon which the Island of Hawaiʻi is built.”
