Kilauea volcano (Hawaii), New Eruption!
Donnerstag Jan 01, 1970 00:00 |
A major change in Kilauea's eruption is in progress starting several hours ago.
-Highest lava lavels within Halemaumau Crater at the summit in recent weeks, which have caused many collapses into the rising lava lake and growth of the crater
-Elevated seismicity in the upper east rift zone over the past 2 weeks, coincident with inflation and pressurization of the volcano
-Decoupling of the tilt signal between the summit and east rift zone 3-4 weeks ago
-Harmonic tremor (indicating magma movement!) within the southwest rift zone in recent days coincident with summit signal
Eruption indicators include:
-Seismicity shifting today to an area below Napau Crater, just west of Pu`u `O`o
-Decrease in tilt of ~125 microradians (in recent years a decrease of ~10 microradians was a lot)
-A new lava fissure about 500m/1600ft in length spotted by helicopter erupting across Napau Crater
-Collapse of Pu`u `O`o crater floor by an unknown amount, estimated ~150m/500ft
-Receding of the Halemaumau lava lake, continuing at the time of this post
Other notable events:
-Heavy rain-showers of up to 5in/12cm today on much of Kilauea's southern flank
-Closure of the Chain of Craters Road by the National Park -- no access to the eruption at present.
-On January 30, 1997, a 24-hr eruption occurred within Napau Crater, with a similar collapse of Pu`u `O`o. That eruption resumed at Pu`u `O`o 24 days later!
There's no telling what comes next other than to wait and see!

Kilauea volcano (Hawai'i) activity update: Longest non-eruptive period since 1982; probable end of 1983-2018 eruption
Samstag, Nov 10, 2018
It has now been 66 days since lava was last at the surface at Kilauea. That is the longest gap since the start of the eruption in 1983- there were 65 days between Episode 2 and 3- and the longest since the 4 months between the two 1982 eruptions. And with no signs of imminent renewal, it seems very likely that the current gap will reach the 90 day mark on December 5- which means the eruptive period that started in 1983 has come to end. When eruptive activity does eventually return, it will be an entirely new eruption. [mehr]

The Hawaiian Volcano Observatory has lowered the Aviation Color Code and Alert Level for Kilauea to YELLOW/ADVISORY, stating that the likelihood of renewed eruptive activity in the near-future is unlikely. [mehr]
Kilauea volcano (Hawai'i) activity update: Eruptive hiatus continues, gas emissions at lowest levels since before 1983.

Activity at Kilauea remains at very low levels, with no eruptions anywhere on the volcano, as has been the case since early September. ... [mehr]

As the eruption of lava from Fissure 8 continues with little changes, but rather an increase as observed last evening, lateral outbreaks from the lower parts of the lava channel have been feeding a broad flow front that is now advancing southwest and threatens to inundate the Pohoiki boat ramp in Isaac Hale Park.
