Last Tuesday, a M5.2 earthquake struck the Hawaiian active volcano formerly known as Loihi. Now called Kama‘ehuakanaloa, this was followed by a swarm of earthquakes, potentially signaling minor signs of unrest. Today's video analyzes this earthquake swarm, and ranks it in comparison to other historical earthquake swarms at this volcano.
