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.
Volcanic hazards in Kona (i.e. the western side of the island of Hawai'i) stem primarily from Mauna Loa and Hualalai volcanoes. The former has erupted 39 times since 1832. Lava flows were emplaced in Kona during seven of these eruptions and last impacted Kona in 1950.
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).
Zone 3 includes areas gradationally less hazardous than zone 2 because of greater distance from recently active vents or because the topography makes it less likely that flows will cover these areas. Developed areas between Kea`au and Pahoa and on the south side of Highway 11 between Kea`au and Volcano are in zone 3.
Kilauea volcano is not eruptingThe eruption that began on September 10, 2023 has ended. No lava fountains, flows, or glow are visible at this time. Read the activity summary of Kilauea, courtesy of USGS.
Tsunami that hit Hawaii don't always come from distant earthquakes. Although not as frequent, tsunami can also be generated by underwater volcanic eruptions. A very recent example of this is the Hunga-Tonga Hunga-Ha?apai eruption in 2022.
