Volcano news & updates: Kilauea volcano (Big Island, Hawaii)
Kīlauea volcano (Hawai`i) activity update: Pu`u `O`o overflow, pressure builds!
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!

At the same time, an unusually large number of earthquakes are being located in the upper east rift zone (between Halema`uma`u and Mauna Ulu, site of the bend in the rift zone) which indicates pressurization there, too! A similar earthquake pattern occurred in the last two weeks of February this year in the build-up to the eruption of the new Kamoamoa fissure.
The question remains whether the overflow from Pu`u `O`o will persist and establish a pressure relief quickly enough, or whether the building pressure forces open a new fissure before then! In the first case we could have lava flowing downslope towards the ocean and into public access, or in the second case we could see another "curtain of fire"! Stay tuned!

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! ... Lees alle

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. ... Lees alle

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. Lees alle

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. Lees alle
