Volcano Watch — Lava flow continues in starts and stops

Last week we noted that, based on the activity in the pond inside Pu`u `O`o cone, the lull in activity at the episode 51 vent was probably just another pause in episode 51. Sure enough, the vent again began erupting Sunday morning about 9:30 a.m., or about the time you were reading about the eruption in last Sunday's paper.

Volcano Watch — Eruption pauses; earthquake shakes isle

The eruption at the episode 51 vent slowed dramatically on Thursday at about 2:00 p.m. and by Friday morning there was no eruptive activity at the vent on the west flank of the Pu`u `O`o cone. The activity in the pond inside the Pu`u `O`o cone suggests that the current lull in activity is just another pause in episode 51.

Volcano Watch — No episode 52 after all, just repeats of 51

With the wisdom of hindsight, we have concluded that the continuing episodic eruptive activity from the vent on the west flank of the Pu`u `O`o cone is a single episode with pauses, rather than a new episode with each eruption at the vent. We are therefore continuing to call the activity that began on March 7 "episode 51."

Volcano Watch — Newest episode likely to stop flowing in weeks

Episode 50 began about 7:30 p.m. on Feb. 17 from a small fissure just southwest of the Pu`u `O`o cone. By the 19th, only about 100 feet of the original fissure was still active. The activity has since settled down at one main point near the northeastern end of the fissure. By Friday, this vent had created a spatter cone almost 25 feet high.

Volcano Watch — Kupaianaha vent appears to be winding down

Since at least April 1991, the volume of lava erupted from the Kupaianaha vent has steadily declined. Since late November, the remaining lava flows have been limited to a single area near the 1,850-foot elevation, less than two miles downslope of the vent.

Volcano Watch — Mauna Loa comes under military-style surveillance

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.

Volcano Watch — Kīlauea Volcano divided into lava-risk zones

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.

Volcano Watch — The Big Island is sinking under weight of volcano

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.

Volcano Watch — Earthquakes swarm beneath Kīlauea Volcano

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.

Volcano Watch — East Rift eruption continues at low, steady level

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. ...
