![]() ![]() However, it will probably take lava from the northeast rift zone at least a week to reach populous regions, giving people time to flee if necessary. Shield volcanoes like Mauna Loa are so named because they have long, broad flanks that resemble a warrior's shield.ĭepending on where it flows, molten rock may cover homes, farms, or entire neighbourhoods. Its summit has collapsed to form a caldera, a broad shallow depression. Kilauea is 4,090 feet (1,250 meters) high. The name Kilauea means Much Spreading in Hawaiian, referring the spreading of the volcano’s lava. Due to this, lava may now begin to flow down the side of the volcano and magma's gas can escape. Like Mauna Loa, Kilauea is a shield volcano, a large, dome-shaped mountain built by highly fluid lava flows. ![]() The magma of Mauna Loa is typically hotter, drier, and more fluid. Named after the Hawaiian goddess of volcanoes, Pele, the glass particles are created when hot lava erupts from a fissure and immediately cools. Those who have asthma or other respiratory issues may need to go to the hospital as a result. Vog can cause headaches, sore throats, and burning eyes in healthy persons. Hawaii's health experts are advising people to limit outdoor exercise and other activities that cause heavy breathing. When they combine with vapour, oxygen, and dust in the sunlight, they produce volcanic smog or vog. Mauna Loa is spewing sulphur dioxide and other volcanic gases. Since September 2021, the Kilauea volcano, which is its smaller but more active neighbour, has been erupting continually. The summit of Mauna Loa has been the site of around half of the volcano's known eruptions. Scientists predict that the current eruption will proceed in this manner. Lava that occasion moved in the direction of Hilo but stopped a few kilometres outside of the city.Įvery Mauna Loa eruption in the past has lasted a few weeks. In 1984, Mauna Loa also experienced a northeastern eruption. When measured from the ocean floor to its top, Mauna Loa is thought to have a volume of at least 18,000 square miles (75,000 square kilometres), making it the largest volcano in the entire globe. ![]() The state capital, Honolulu, and the beach resort Waikiki are both situated about 200 miles (320 kilometres) south of Hawaii's most populous island, Oahu. The Big Island is primarily rural and is home to cattle ranches and coffee fields. However, there are a few minor communities on the Big Island, including the county capital of Hilo, which has a population of 45,000. As a result, the top of the volcano is about 17 kilometres (10.5 miles) above its base, according to the USGS. Since Mauna Loa is so massive, its submerged flanks extend for miles to an ocean bottom that is itself lowered. ![]()
