What year did Mt Kilauea last erupt?
Kilaueua's most recent eruption started in 1983 and is still continuing today.
There are many volcanic mountain chains in the USA, so it stands to reason that there are many possible mountains that could erupt. Mt. Rainier shows signs of activity and Mt. St. Helens has erupted in the recent past and may again in Washington state. Mt. Shasta in California is another possibility. Mt. Kilauea and Mt. Mauna Loa in Hawaii erupt almost regularly.
