Kīlauea flows continue without interruption
May 13, 1994

The eruption along Kīlauea's east rift zone continues without interruption. Following the last pause in activity in the middle of April, the tube was reoccupied from the vent 51 and 53 areas adjacent to the Pu'u 'O'o cone to just above Paliuli, upslope from Kamoamoa.

Kīlauea is famous for eruptions of the type we are now experiencing--quiet effusion of lava that makes the eruption approachable. However, not all of Kīlauea's eruptions have been so passive and approachable.

The past week has been eventful with many changes in the on-going eruption. The eruption stopped once again starting Thursday, April 14, in the afternoon, and lava had stopped entering the ocean by about 5 p.m.

The eruption along Kīlauea's east rift zone continues without interruption. The lava is erupting from two vents, which we call the episode 51 and 53 vents, located on the west and south flanks of the Pu'u 'O'o cone, and transported downslope in a long-lived tube system.

The U.S. Geological Survey's Hawaiian Volcano Observatory is located adjacent to the Thomas Jaggar Museum on the rim of Kīlauea caldera. The Observatory was founded in 1912 as a laboratory of the Massachusetts Institute of Technology by Thomas A. Jaggar, a pioneering volcanologist.

Friday, March 25, marked the tenth anniversary of the last eruption of Mauna Loa Volcano. The 1984 eruption followed a nine-year period of quiescence. Roughly three years of increasing frequency of shallow- and intermediate-depth earthquakes preceded the eruption.

Following the spectacular display of steam explosions and lava fountaining at the ocean entries last week, this week began with another pause in the eruption. By last Sunday morning, lava had stopped entering the ocean, and the lava tube upslope was drained and empty, although still brightly glowing.
 

Volcano erupts in big show
March 11, 1994

Lava activity at the coast where the flows enter the ocean has been spectacular this past week. The activity has included high lava spattering and formation of three new cones along the ocean entries. On Friday, March 4, explosions began at the coast and intensified during the day.
