What is the biggest volcano in the U.S.A?
Alexander R. Benson
Alex,
Undoubtedly the biggest volcano in the USA is
Mauna Loa
on the
island of Hawaii. It is huge, rising about 4 km above sealevel, and
extending about 6 km BELOW sealevel. So Mauna Loa is about 10 km (6
miles) high! It is the biggest volcano on the Earth.
