Isn't that dangerously close to the Mauna Kea telescopes? I don't see
anything mentioning them.

Subject: [Rockhounds] Earthquake Swarm Hits World’s Largest Volcano

An earthquake swarm continues on Mauna Loa, known as the world’s largest
active volcano. While nearby smaller Kilauea Volcano is erupting, Mauna Loa
is not yet at this time. But that could change with time.

Beginning at 2:30 am HT on March 29, 2021, the U.S. Geological Survey’s
(USGS)  Hawaiian Volcano Observatory (HVO)  recorded over 130 earthquakes
beneath the northwest side of Mauna Loa’s summit, about  26 miles west
northwest of the town of Volcano, Hawaii.   According to HVO, most of these
earthquakes are occurring in a cluster about  1 mile  wide and  3.5–5 miles
below the surface.

The swarm continues this morning, with a 2.6 earthquake recorded in Pahala
at 2:03 am HT.

The largest event in the sequence, so far, was a magnitude-2.7 earthquake,
with the bulk of the events being less than magnitude-2. Only one event was
reported felt by a resident and was described as weak shaking with a maximum
Intensity of II on the Modified Mercalli Intensity Scale.
