HAWAIIAN VOLCANO OBSERVATORY STATUS REPORT U.S. Geological Survey Monday, June 3, 2024, 2:59 PM HST (Tuesday, June 4, 2024, 00:59 UTC) The eruption that began southwest of Kīlauea’s summit at approximately 12:30 a.m. HST this morning, June 3, has paused. However, activity in this region remains dynamic and could change quickly. HVO continues to closely monitor Kīlauea and will issue additional notices as needed. Visual observations suggest that effusion of lava ceased by approximately 12:30 p.m. HST today. Lava flows were sluggish between 11–12 p.m. HST and had ceased moving by approximately 12:30 p.m. HST. However, areas of incandescence and elevated volcanic gas emissions continue. At approximately 7:45 a.m. HST this morning, a sulfur dioxide emission rate of approximately 15,000 tonnes per day was measured; this emission rate had decreased to 12,000 tonnes per day as of noon and has likely decreased further this afternoon. Volcanic tremor, a signal associated with fluid movement, continues to be recorded on summit seismometers though at a slightly decreased intensity. Earthquake activity decreased greatly in the summit region of Kīlauea with the onset of the eruption. All seismicity for the last 8 hours is concentrated near Maunaiki at the western extent of the system of cracks that opened during this eruption. Ground deformation has been characterized by slow summit deflation since 2 a.m. HST, suggesting that magma may still be moving from summit storage to the southwest into the eruption area. |

Subject: a few pics from the earlier stages of this eruption..

Pictures taken early this morning, more or less 6 hours after the event began.. the first shows an earlier pass right at dawn with an active set of fissures, although not very vigorous, there's more than was seen in a later pass (second pic) only a half hour later.. This is a very low level event, and most likely a part of the volcano reinflating after the 2018 drawdown, and can be expected to end shortly.. although I should note we've seen events happen like this, low level not very vigorous, that then went on for years at the same low level of activity. By low level I mean less than 1 million cubic meters a day, more like half that. And still, that much everyday can accumulate, so I add the qualifier. If this event were to go on for an extended period of time there is no developed property in any path flows from it might take..   Right click on an image and select open image in new window to see it in a much larger scale in a new window. Source URL for pics at the link above.. |

Subject: Kilauea Now Erupting..
Well, before I went to bed it looked like the volcano was beginning a play to the ERZ but before I woke up she decided to punt. The ground opened up just southwest of the summit caldera around 12:30am. There's no cameras in the area and the map below is the first data posted showing the approximate location of the initial outbreak.. |

Following the EQs this event now looks as if an intrusion is underway into Kilauea's East Rift Zone. |

Subject: Here's the deformation (tilt plot) that goes with this event..
Note that this file is not static.. but rather will update itself (you have to reload the page) every 10-15 minutes.. and it's been estimated, over the last 30-40 years, that this particular tilt station's changes to be in the area of one microradian (the tick marks on the left of the plot) equals about 1 million cubic meters of magma.. |
