Where is mauna loa located

In fact, using this last measure of its height, it is one of the tallest mountain in the world although many mountains, such as Mt. Everest in the Himalaya mountain range, sit higher relative to sea level. All large land masses such as mountains also push down upon the Earth's crust due to their enormous weight. So, directly beneath Mauna Loa, the sea floor on which it sits is depressed by and additional 26, ft m. Thus, if one wanted to say how thick at its center is the lava pile that makes up Mauna Loa, one would need to add its above sea level height, its sea floor to sea level height, and the thickness of its depression in the Pacific sea floor.

These total 56, ft 17, m. For more details about estimation of the actual thickness of Mauna Loa volcano, see the write up on "How high is Mauna Loa volcano" at the HVO website. Mauna Loa Awakening? The summit of Mauna Loa began inflating slowly between and after a decade of slight deflation, after experiencing a brief swarm of deep long-period earthquakes.

Inflation wasn't constant, with slowdowns in winter , Spring , and since sept But, inflation was fairly steady in and the first half of following a more intense swarm of several thousand deep earthquakesin late , all of which suggested that the magma reservoir within the volcano was swelling.

Then inflation slowed again in , ceased in late , and resumed slowly in late , continuing through mid i. Im late Aug , HVO raised the alter level at Mauna Loa because of long-term increased seismicity rates and inflation of the summit as measured by cross-caldera difference.

This doesn't mean an eruption is imminent, but signs are consistent with magma entering the shallow part of the magmatic system at the volcano. Earthquakes activity increased in early July and continued through Fall , but then slowed significantly throughout and remained at a level of about 10 a week. Activity peaked in Sept. That earthquake swarm was the greatest number of such earthquales since the beginning of the modern HVO earthquake catalog in the s.

Meaning "long mountain" in Hawaiian, it is the quintessential shield volcano in its shape— signified by broad, rounded slopes. More impressive, however, it rises an astonishing 30, feet 9, m from the bottom of the sea, a greater height than Mount Everest.

Mauna Loa is among Earth's most active volcanoes, having erupted 33 times since its first well-documented historical eruption in It has produced large, voluminous flows of basalt that have reached the ocean eight times since It last erupted in , when a lava flow came within 7.

Mauna Loa is certain to erupt again, and with such a propensity to produce large flows, we carefully monitor the volcano for signs of unrest. Skip to main content.
