While Maui is home to two large shield volcanoes, Haleakala and Mauna Kahalawai, both are considered dormant.

* Haleakala is the largest volcano on Maui and is the most recent to erupt, around 1790. However, it is currently considered dormant.

* Mauna Kahalawai is much older and extinct.

It's important to note that volcanism is a long-term process, and dormant volcanoes could become active again in the future.
