If going to the world’s biggest volcano seems dangerous, think again: not all volcanoes erupt with left and leave cities covered in molten lava and ash. While it undoubtedly true that volcanoes, like Mount Tambora in Indonesia and Mount Vesuvius in Italy, do really present threats, many volcanoes are far less spectacular.
Such is the scenario with Hawaii’s Mauna Loa, which happens to be the planet biggest active volcano, by both volume as well as size. Mauna Loa is situated in the island of Hawaii, which will be the biggest isle in the archipelago itself-it’s name means Long mountain in Hawaiian.
Along with four other volcanoes, it forms the very construction of the island. Mauna Loa is recognized as a shield volcano, meaning which is made by the flow of lava with time. When quantified, Mauna Loa’s lava tallies greater than 56, 000 legs, though its real elevation is only 13, 679 feet.
It’s theorized that the isle of Hawaii took almost 1 million years to form. It started when the island’s five volcanoes erupted throughout the ocean floor. Geologists estimate that Mauna Loa is erupting for some 700, 000 years and peaked its head above water only 400, 000 years ago.
Today, Mauna Loa carries on to expel lava, so adding acreage of the ever growing island. What may be said of Mauna Loa explosions? Quite simply, Mauna Loa does not have them. Deemed a non explosive volcano because of the low silica content of its lava, Mauna Loa has very fluid outbreaks.
Native Hawaiians have already been present on the isle for about 1, 500 years, but left small record of volcanic action from Mauna Loa. The last eruption was in the year 1984, when lava flow emerged from the peak and headed downslope toward Hilo, the island’s biggest city.
The lava lost city limits by approximately four miles, but was so bright that it lit the city during the night. Mauna Loa continues to be fairly quiet, although experts claim to see signs that it might wake in the future. Moana Loa is an incredibly popular traveller destination, attracting some two million visitors every year to Hawaii’s Volcanoes National Park. It isn’t Moana Loa that is doing the erupting, of course-it is the neighboring volcano, Kilauea, which is presently erupting from two places.
Mauna Loa also holds the difference to be part of the volcano club, of sorts. The International Association of Volcanology and Chemistry of the Earth Interior incorporated Mauna Loa in a group of sixteen volcanoes, known as Decade Volcanoes. Such volcanoes are of specific interest due to both their high degrees of action and their distance to large population centers.
