Question: how rare is it for Hawaii volcanoes to errupt?

Elena Maters answered on 24 Nov 2019:

There are 3 volcanoes in Hawaii that are considered to be still active. Loihi last erupted in 1996. Mauna Loa erupted in 1984 and is expected to erupt again in the next few years. Kilauea erupted in 2018 and its lava flows destroyed hundreds of homes, and some of its lava fountains from fissures in the ground reached 90 m high! It is one of the most active volcanoes in the world, with over 60 eruptions in the past ~250 years, which is an average of about 1 eruption every 4 years!
