Audio report on the study of underwater
volcanoes, by Neal Conan on NPR's Weekend Edition
Saturday (June 13, 1998). Discusses efforts to make
recordings of the sounds of an underwater volcano off the
coast of Hawaii. Includes an interview with geologist and
volcano expert Fred Donnebier.
Active volcanoes are not scattered over
the Earth randomly; instead, most occur in belts, especially
in the island arcs and mountain ranges bordering the Pacific
Ocean (Figure 5). The concept of seafloor spreading and, more
broadly, the theory of plate tectonics offer a logical
explanation for the...
Volcanoes National Park
national park encompassing a volcanic
area along the southeastern shore of Hawaii Island, U.S.,
southwest of Hilo. Established in 1961 and formerly a part of
Hawaii National Park, it occupies an area of 359 square miles
(930 square km) and includes two active volcanoes--Mauna Loa
from various types of volcanic
The list of hazards associated with
volcanic eruptions is long and varied: explosions, toxic gas
clouds, ash falls, pyroclastic flows, avalanches, tsunamis,
mudflows, and lava flows, as well as secondary effects such as
fluoride poisoning, starvation, and
The 5 percent of known world volcanoes
that are not closely related to plate margins are generally
regarded as hot-spot volcanoes. Hawaiian volcanoes are the
best examples of this type, and though they occur near the
centre of the northern portion of the Pacific Plate, they show
Mongibello, active volcano on the east coast of Sicily. The
name comes from the Greek Aitne, from aitho, "I burn." Etna is
the highest active volcano in Europe, its topmost elevation
being more than 10,000 ft (3,200 m). Like other active
volcanoes, its height varies: in 1865, for
of the Kamchatka Peninsula, far eastern Russia. It is one of
the highest active volcanoes in the world, rising to a height
of 15,584 feet (4,750 m), the highest point on the peninsula.
The volcano consists of a truncated cone with a central
crater, with some 70 lateral craters
any of various processes and phenomena
associated with the surficial discharge of molten rock or hot
water and steam, including volcanoes, geysers, and fumaroles.
Although volcanism is best known on the Earth, there is
evidence that it has been important in the development of
other planets such as...
There are some 220 active volcanoes in
Indonesia and many hundreds that are considered extinct. They
run in a crescent-shaped line along the outer margin of the
country through Sumatra and Java as far as Flores and then
loop north through the Banda Sea to a junction with the
volcanoes of northern...
