Mauna Loa volcano

Mauna Loa volcano in Hawaii: Earthquakes rattle, warning of an eruption

At the world’s most active volcano, more earthquake swarms were detected.

According to the U.S. Geological Survey, Mauna Loa is still experiencing heightened unrest on Big Island.

The observatory detected 13 small-magnitude earthquakes in areas that were historically seismically active during periods when the volcano was not active.

Monitoring data has not shown any significant changes in the last 24 hours. However, an increase in an activity doesn’t suggest an imminent eruption and there are no signs that it is likely.

Scientists will keep an eye on Mauna Loa to see if there are any changes.

More than 60 GPS stations are used to measure the amount and location of magma below the surface.

A thermal webcam is located at Mauna Loa’s summit. Satellite radar is also available.

Current unrest, also indicated by the inflation of the summit, is most likely caused by renewed magma input 2-5 miles below the summit.

Mauna Loa is half of Hawaii.

There are often rapid lava flows from eruptions that can affect communities on both the east and the west sides of the island.

The volcano has erupted 33 times since its 1843 eruption, its most recent eruption being in 1984.

Officials warn residents to be ready in the event of an eruption.
