Is it common for volcanoes to erupt in Hawaii?

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.

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.

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.
