According to the US Geological Survey, the most recent eruptions in this series of activity occurred between about 70,000 to 100,000 years ago. There is a possibility that Koʻolau volcano could erupt again; however, the chance of such an eruption occurring in "our lifetimes, or even those of many future generations" is remote.
