What is Hawaii’s most dangerous volcano?
A recent PBS documentary identified Kilauea, on the island of Hawaii, as “the most dangerous volcano in the world”. A curious choice, in my opinion, for any assessment of the danger of a volcano is to take into account both the intrinsic danger and the number of lives at risk. Kilauea’s eruptions are certainly spectacular.

Which volcanoes had the longest eruptions?
Did Mauna Loa kill anyone?

What is Hawaii’s largest active volcano?
Aerial view of Mauna Loa volcano, Hawaii. Scientists at the USGS Hawaiian Volcano Observatory monitor Mauna Loa, the largest active volcano on Earth. In this 1985 aerial photo, Mauna Loa hovers above the summit caldera of Kīlauea Volcano (center left) and nearly obscures Hualālai in the distance (top right).
How big is the biggest volcano in the world?
The team found that Pūhāhonu contains about 36,000 cubic miles (150,000 cubic km) of rock, giving it a volume more than twice that of Mauna Loa. These two small peaks, called the Gardner Pinnacles, are all that is visible of the largest volcano in the world. (Image credit: NOAA)
