Kilauea volcano (Hawai'i): summit crater lake grows, volcano remains calm
Tuesday Aug 27, 2019 18:57 PM | BY: T
The volcano continues to be calm at the surface with no sign of new volcanic activity in the short term.

However, some recent changes involve the formation of a slowly increasing hot, green crater lake inside Halema'uma'u summit crater. HVO reported that it had been growing over the past days, rising 10 cm in just two days, and now measuring approx. 20x30 m.
Measurements made found its surface to be a 70 deg C temperature. No significant degassing was observed from the lake itself, but new fumaroles formed a few meters away from the lake along a ground crack.
The temperatures of the escaping gasses at these fumaroles were moderately hot, at 200 deg C, suggesting that although magma is present in the reservoir, it is currently not very close to the surface. This also corresponds to other monitoring parameters showing that the volcano remains calm for the time being.

Kilauea volcano (Hawai'i) activity update: Longest non-eruptive period since 1982; probable end of 1983-2018 eruption
Saturday, 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. [more]

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. [more]
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. ... [more]

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.
