Hawaiʻi's Active Volcanoes. Two of the world's most active volcanoes - Kīlauea and Maunaloa - can be found on Hawaiʻi Island. Maunaloa last erupted in 1984, and Kīlauea's last eruption was 1983-2018. Other volcanoes on Hawaiʻi Island include: Maunakea, Hualālai, and Kohala.

How did volcanic eruption happen?

Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth's surface.

Where did the lava flow in Hawaii?

By the morning of June 3, the lava flow from ʻAhuʻailāʻau had reached Kapoho and Vacationland Hawaiʻi, where it then destroyed hundreds of houses as it buried most of the town within a day. Lava also entered the Puʻu Kapoho crater and evaporated the 400-year old Green Lake inside the crater, the largest natural freshwater lake in Hawaiʻi. The flow entered the ocean at Kapoho Bay at about 10:30 PM HST that evening, creating plumes of laze, and began to fill the bay, building a lava delta that reached about 700 yards into the water by late afternoon on June 4. By June 5, the lava had completely filled the bay, and preliminary reports from Hawaiʻi County officials indicated that hundreds of homes had been destroyed.

Eruptions occurred in this same area in 1960 (Kapoho), 1955 (steam vents on Highway 130 to Halekamahina), 1840 (Ka‘ohe Homesteads through Nanawale Estates), about 1790 (Lava Tree State Monument) and earlier. These previous eruptions happened well before geothermal operations began on the LERZ.

How long has Kilauea been erupting?

By April 2018, Kilauea had been erupting essentially nonstop for more than 35 years. It was inevitable that, at some point, the Pu‘u ‘O‘o eruption would end and another eruption would begin on the volcano.

What zone is Kilauea in?

Thus, it’s a matter of “when” — not “if” — an eruption will occur on Kilauea. The rift zones and summit on Kilauea (and Mauna Loa) are identified as Zone 1 on the USGS Lava-Flow Hazard Map for Hawaii Island, which is where the majority of erupting vents have been located in recent centuries.

What year did the LERZ eruption occur?

The combination of repeated pre-geothermal LERZ eruptions (1790, 1840, 1955, and 1960), the clear movement of magma from Pu‘u ‘O‘o into the LERZ and the temporary halt in magma propagation west of the geothermal development all indicate that geothermal operations played no discernible role in triggering the eruption.

Is Kilauea volcano erupting?

Kilauea Volcano is not erupting and its USGS Volcano Alert level remains at Normal. Rates of seismicity, deformation and gas release have not changed significantly during the past week. Deformation signals are consistent with refilling of Kilauea’s deep East Rift Zone magma reservoir.

Is Kilauea a volcano?

We’ll explain by starting with some facts about the volcano. First and foremost, Kilauea is one of the most active volcanoes in the world. The exposed part of the volcano covers itself with new lava every thousand years or so. Thus, it’s a matter of “when” — not “if” — an eruption will occur on Kilauea.

Where is the easternmost point of the Kilauea magma?

After another short pause, the magma continued its subsurface advance until it reached its easternmost point near the south end of Halekamahina Road. The subsequent opening of 24 fissures in the vicinity of Leilani Estates on Kilauea’s LERZ was not unprecedented or particularly surprising.
