There are currently two active lava
flows on Hawaii’s Kilauea Volcano: the Kahaulae’a 2 flow, and the Peace
Day flow. Both begin at Pu’u O’o, the center of Kilauea’s current
eruption for most of its 30-year history. The Kahaulae’a 2 flow began on
May 6, 2013, and currently extends into the forest about 2.6 kilometers
(1.6 miles) north of the vent.
Lava from the Peace Day flow—which began on September 21, 2011—runs
to the southeast through a lava tube. The tube insulates the lava and
allows some of it to flow into the Pacific Ocean, more than 12
kilometers (7.5 miles) from Pu’u O’o. A small portion of the lava is
diverted to the surface in a series of breakouts at the base of the
pali, cliffs that parallel Hawaii’s southeast coast .
Bright red dots in this false-color (a combination of shortwave
infrared, near infrared, and green light) satellite image indicate the
location of fresh lava on the surface. Bright green shows dense
vegetation, while brown marks sparse vegetation, particularly along the
arid coastline. The black region surrounding Pu’u O’o are the lavas
emplaced since the current eruption began in 1983. Ocean is blue-black,
visually separated from the lava fields by a bright blue-green line of
surf. This image was collected on June 27, 2013, by the Advanced Land
Imager (ALI) on the Earth Observing-1 (EO-1) satellite.
