The internal workings of Mauna Loa Volcano will be probed from space starting this week by a satellite system designed to track military vehicles rather than volcanoes.

Kīlauea Volcano divided into lava-risk zones...
January 31, 1992

Kīlauea is the world's most active volcano. About 70% of Kīlauea's surface is covered by lava less than 500 years old and over 90% is covered by lava less than 1,100 years old. Much of the surface of Kīlauea Volcano lies within Hawai`i Volcanoes National Park, where eruptions are generally welcome tourist attractions.

A magnitude 3.8 earthquake occurred about 15 miles beneath Mauna Kea Volcano at 1:48 a.m. on January 21. Similar deep earthquakes occur persistently beneath the Big Island but are not restricted to any particular location.

Earthquakes swarm beneath Kīlauea Volcano...
January 17, 1992

The most notable event on Kīlauea Volcano this past week was a swarm of small earthquakes, mainly on January 13. This swarm included two earthquakes with magnitudes larger than 3.0 (see figure) and numerous smaller earthquakes.

The eruption on the East Rift Zone of Kīlauea Volcano continues with low-volume, steady effusion of lava from the breakout at about the 1,900-foot level of the tube downslope from the Kupaianaha vent. This is the same area that has had active flows for the last several weeks. Tremor continues at low levels in the upper East Rift, indicating that magma continues to move in the rift zone. 
 

Eruption's 10th year begins...
January 3, 1992

Nine years ago on January 3, 1983, the ongoing eruption on the East Rift Zone of Kīlauea Volcano began when a discontinuous 3.7-mile long series of fissures opened in, and downrift of Napau Crater.

December 27, 1991

Kīlauea Volcano continues to erupt from the Kupaianaha vent on the East Rift Zone. The volume of lava moving down the Waha`ula lava tube from the Kupaianaha vent has decreased slowly since April 1991, with a short sharp decrease and subsequent increase during and after episode 49 in November.

December 20, 1991

During a typical week, 300-400 located earthquakes occur beneath the Big Island, as recorded on the U.S. Geological Survey's seismic network. However, only a few have magnitudes greater than 3.0, roughly the threshold for felt earthquakes.

December 13, 1991

Kīlauea Volcano continues to erupt from the Kupaianaha vent on the East Rift Zone. The episode 49 fissure that opened between Pu`u `O`o and Kupaianaha on November 8 remains inactive.

December 8, 1991

Kīlauea Volcano continues to erupt from the Kupaianaha vent on the East Rift Zone, while the episode 49 fissure that opened between Pu`u `O`o and Kupaianaha on Friday, Nov. 8, has shut down in the last few days. 

Volcano Watch (no. 5)...
November 29, 1991

Kīlauea Volcano continues to erupt from both the Kupaianaha vent on the East Rift Zone and from the new episode 49 fissure located between Pu`u `O`o and Kupaianaha. The output of lava from each vent continues to decline, with the output from Kupaianaha nearly stopped.

November 22, 1991

Kīlauea Volcano continues to erupt from both the Kupaianaha vent on the East Rift Zone and from a new fissure that opened the morning of November 8th between Pu`u `O`o and Kupaianaha.
