Kīlauea volcano (Hawai'i), activity update: new lava flow
Thu, 4 Aug 2011, 03:0603:06 AM |
At 2pm local time, the western base of Pu`u `O`o cone began to erupt a new lava flow, which has advanced at least 3km/1.8mi downslope in the first 2 hours. Meanwhile, Pu`u `O`o's crater floor and perched lava lake have collapsed, sending up clouds of brown ash. There is no earthquake swarm associated with this new breakout, suggesting a collapse of the old edifice as opposed to a new gas-fed fissure, as the Kamoamoa Eruption earlier in March. Other supporting evidence is a smaller magnitude change in tilit and no sustained high-amplitude tremor at the eruption site.

As the sun sets in Hawai`i, there should be spectacular views in at least 3 different webcams on Kīlauea volcano, where lava is visible! Check the links below, including one to our picture from Napau crater of overflows last week!
We will monitor the situation and post further updates as major changes occur. At present, the National Park has closed the Chain of Craters Rd, so there is no legal way to access the eruption site on the ground until further notice. Air tours should still be possible.

Kīlauea volcano continues to pressurize with new magma, uplifting the floor of Pu`u `O`o crater on the order of 1 meter / 3 feet PER DAY over the last month! This uplift has allowed lava flows to emit from the base of the inner crater walls, filling the neighboring craters (MLK & Puka Nui) to overflowing to the southwest starting last night! The inner crater lava flows show up via webcam (check our link below), with visible cracking occuring as the whole crater floor is pistoned upwards! ... read all

Magma continues to inflate Kilauea volcano and feeds two rising lava lakes, one in Halema`uma`u Overlook Vent (within 125m/410ft of the crater rim) and another within Pu`u `O`o Vent (within 52m/170ft of the east crater rim). Local officials continue to forbid direct access to both sites, but strong glow is visible from both craters on a nightly basis from legally accessible points. The question now is whether either crater will fill enough to spill over, or whether the increased pressure will cause an adjustment and possible eruption somewhere else, as it did this past March! Thanks to the USGS-HVO, there are near-live webcams into both craters, with spectacular views day and night (see links below). Stay tuned! ... read all

Lava returned to the crater floor of Pu`u O`o crater this morning, covering it with a small lava lake. The new eruptive episode marks the end of one of the longest pauses in the eruption so far. It followed a day of inflation, first at the summit, then under the eastern rift zone, indicating the rise of underground magam filling the plumbing system again. ... read all

The east rift zone, site of the recent spectacular eruptive episode in Napau crater, is still pausing. No lava is being erupted at present. Also the lava level inside the Halema`uma`u vent has dropped and the summit has been deflating in recent days. Is this the end of one of history's longest-lived eruptions documented ever, or simply a pause? The following weeks will probably tell. read all

After several days of activity, the Kamoamoa fissure eruption in the Napau crater on Kilauea's E rift zone has stopped or paused. Lava emission stopped late on March 9 local time. Both the rift zone and summit are showing deflation and seismic tremor and SO2 output were diminishing, indicating a temporary exhaustion of magma supply in the shallow reservoir. read all
