Mauna Loa volcano eruption

Mauna loa Hawaii erupts for the first time in more than 40 years. The largest volcano on earth He has decided to wake up from his lethargy. Mauna Loa began to erupt last night with new fissures opening at the top of the volcano.

We are going to tell you all the news about the eruption of the Mauna Loa volcano.

Mauna Loa volcano eruption

A new eruption of Mauna Loa was seen in Hawaii at 2:16 am. Mauna Loa erupted early yesterday from its uppermost crater, Moku'āweoweo. The Giant Shield Volcano on the Big Island of Hawaii it has not been active for 38 years. The eruption followed the contours of most Hawaiian-style eruptions, with a fissure at the top, lava fountains, and lava flows emerging from new vents.

Due to this new activity, the USGS Hawaii Volcano Observatory changed the alert status for Mauna Loa to Red/Warning. Currently, there is no threat to residents around the volcano, as the eruption is likely to be confined to the summit. However, from the edge of the summit, lava flows quickly covered the ground.

The USGS reports that lava flows have spilled southwest from the summit crater, but the eruption is still coming from the summit. However, the opening of new ventilation shafts outside the summit crater is not ruled out.

Arctic lava flows have occurred on all sides of Mauna Loa, some of whom came to what is now Hilo in the 1880s. It also has the potential to generate currents that can reach from South Kona to the other side of the island. Therefore, there is a threat of lava flows that could reach the southwest, northeast, and northwest of Mauna Loa. Depending on the intensity of the eruption, volcanic fog can also be a respiratory hazard.

historical eruptions

As maps of lava flows from the last 200 years show, Mauna Loa is a very active volcano. This eruption interval of nearly 40 years is relatively rare in its modern history. There have been signs in recent months that the volcano is erupting, with increased seismic activity within the volcano. The summit appears to have slightly deformed until a new eruption begins.

The new eruption means that both Mauna Loa and Kilauea are erupting on the big island. Dual eruptions are not uncommon in Hawaii, although there have been some suggestions over the past 1000 years that the two volcanoes may have alternated in activity. Both volcanoes erupted in 1975 and 1984, but only Kilauea has erupted since the mid-1980s.

Both volcanoes are ultimately fed by a hotspot beneath Hawaii: a train of hot mantle that rises from deep within the Earth and melts as it reaches the bottom of the oceanic crust miles below the island. Although both volcanoes were caused by this mantle plume, the isotopic and trace element compositions of the erupting lavas of Mauna Loa and Kilauea vary so widely that studies of the geology of Hawaiian volcanoes. Scientists believe that they may come from different parts of the mantle plume.

I hope that with this information you can learn more about the Mauna Loa eruption and its characteristics.
