Hualalai from the North Kohala coast
A tranquil view of the volcano, Hualalai. It last erupted in 1801, but is still considered active. If it does go off again, it could be very bad news for the Kohala coast resorts and the airport at Kailua Kona, which is built on the flow from one of the last eruptions.
