Kilauea volcano (Hawai'i): summit crater lake continues to grow slowly
Sunday Nov 17, 2019 17:25 PM | BY: MATTHEW
Kilauea volcano is still currently not erupting. The sulfur dioxide emission rates at summit of the volcano is low with steady rates of ground deformation and seismicity. The crater lake inside Halema'uma'u continues to grow slowly.

During the end of September and the beginning of October, HVO tiltmeters recorded inflation of the East Rift Zone near Pu'u O'o. HVO note that data from their GPS stations and Tiltmeters suggest that the deep East Rift Zone magmatic reservoir between Pu'u O'o and Highway 130 is slowly being refilled. HVO stress, however, that there is no pending change in volcanic hazard in this region. Due to the M6.9 earthquake near Kalapana in May 2018, the south flank of Kilauea continues to creep seaward at higher rates.
Samples taken from the crater lake have gone under preliminary analysis. The sample indicates a pH of 4.2 (acidic) along with high concentrations of dissolved sulfur and magnesium. HVO note that this composition may be due to reactions between the magmatic gases, groundwater and the basaltic rocks. Note that this composition is different from rainwater and the groundwater from just south of Halema'uma'u. HVO suggest that this difference is due to the release of magmatic gases are focused under the crater lake.

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]
