Mauna Loa Volcano Update, Magma at 2 Miles Depth, Magnitude 5.0 Earthquake -

At the present, magma at a mere depth of 2 miles underneath Mauna Loa. And, On October 14th, the flank of this volcano produced two moderate magnitude earthquakes, the largest of which was a magnitude 5.0. So, does this mean that Mauna Loa is about to erupt? Why did these earthquakes occur? This video will answer these two questions and give an update on the Mauna Loa volcano.
