For the past 200 years, Mauna Loa and Kilauea have tended to erupt on average every two or three years, placing them among the most frequently active volcanoes of the world. Some intervals of repose between eruptions at a given volcano have been much longer than its long-term average.
During the morning of September 11, Hawaiian Volcano Observatory geologists conducted an overflight of the new eruption within the Kilauea summit caldera. The eruption is occurring in the east portion of Halema?uma?u crater and on the downdropped block to the east, which formed during the 2018 summit collapse.
So when you're on any island other than the Big Island, vog is the only impact that you'll experience from the Big Island's volcanic eruptions. Fortunately, the prevailing winds in the Aloha State are trade winds. So you won't experience vog when you're on any of the other islands, unless there are Kona winds.
The land area classified under Zone 1, the most hazardous, includes volcanic vents in the summits and rift zones of Kilauea and Mauna Loa, Hawai'i's two most active volcanoes. Zone 9, considered the least hazardous region, consists of Kohala, a volcano that has not erupted for 60,000 years.

Indonesia has more volcanoes than any other country in the world. The 1815 eruption of its Mount Tambora still holds the record for the largest in recent history. Indonesia is one of many places located within the world's most volcanically, and seismically, active zone, known as the Pacific Ring of Fire.
The HTA added: “Currently, travel is still welcomed to the island of Hawaii. Visitors are encouraged to contact their hotel accommodations provider and airlines for updates that could affect their stay on island.”
Respectful travel to any of the Hawaiian Islands, including the accessible areas of Maui, is welcomed and encouraged, now more than ever. On October 8th, West Maui accommodations will begin to reopen to visitors again with the exception of Lahaina.
If you're wondering “is Hawaii safe to visit” the answer is a resounding YES! While Kilauea's lava flow remains powerful after an initial eruption on May 3 and series of subsequent earthquakes, the island is not completely shut down – contrary to popular belief.
Although Haleakala is considered dormant, volcanologists say that a future eruption at Haleakala is inevitable- it's not a matter of if, but when. Haleakala is thought to erupt every 200-500 years, and scientists believe the mountain still has some juice left.
Rising gradually to more than 4 km (2.5 mi) above sea level, Hawaii's Mauna Loa is the largest active volcano on our planet. Its submarine flanks descend to the sea floor an additional 5 km (3 mi), and the sea floor in turn is depressed by Mauna Loa's great mass another 8 km (5 mi).
