- Current Update, last updated Oct 31, 2014 17:59 :
Scientists of the USGS Hawaiian Volcano Observatory conducted aerial and ground observations of the June 27th lava flow on Friday, October 31, 2014. As of 5:45 PM, HST, the leading edge of the flow had not advanced, although there were several small breakouts oozing from the flow behind the leading edge. The breakout in the forested area just downslope of the Pāhoa cemetery advanced by over 140 meters (153 yards) over the past 24 hours. By 5:45 PM it had breached a fence line marking private property.
The active lobe near the Pāhoa transfer station was within 25 meters (27 yards) of the transfer station fence by Friday afternoon. The breakout on the opposite (south) margin of the June 27th lava flow near the transfer station engulfed a small cow shelter Friday morning and expanded the flow by about 30 meters (33 yards).
Friday’s overflight revealed many breakouts adjacent to the north edge of Kaohe Homesteads. The most significant is a fairly large breakout advancing north from the widest part of the flow north of Kaohe Homesteads. This lobe advanced by about 350 meters (383 yards) since the previous overflight on Wednesday. Activity along the Kaohe Homesteads side of the flow (the flow’s southeast margin) appears somewhat diminished compared to previous observations. There were no breakouts on the June 27th flow field upslope of the Kaohe Homesteads area.
No changes were noted at Puʻu ʻŌʻō compared to previous overflights. The cross sectional area of the lava tube measured Friday was 1.9 square meters (2.3 square yards), which is less than that measured last week and implies a decrease in the amount of lava flowing through the tube. This observation is consistent with the deflated state of the summit due to the ongoing DI event (DI deflation is often associated with a decrease in the eruption rate of lava from Puʻu ʻŌʻō). A small inflection in summit tilt may indicate the onset of summit inflation at around 4:15 PM, but it is difficult to assess the change without additional data.
Daily updates about Kīlauea's ongoing eruptions, recent images and videos of summit and East Rift Zone volcanic activity, and data about recent earthquakes are posted on the HVO Web site at http://hvo.wr.usgs.gov.
HVO scientists will continue to monitor the flow from the ground overnight and on Saturday. A daily update will be posted in the morning, and status reports will be issued as new information becomes available. Updates are posted at http://hvo.wr.usgs.gov/activity/kilaueastatus.php.

- Volcanic History Overview: Kilauea volcano is one of the most active and best studied volcanoes in the world and is renowned for the accessability of her eruptions. Throughout her history, Kilauea has erupted from three main areas, its summit and two rift zones. Kilauea currently has a summit caldera, but it may not always have been evident. Most eruptions are relatively gentle, sending lava flows downslope from fountains a few meters to a few hundred meters high. Over and over again these eruptions occur, gradually building up the volcano and giving it a gentle, shield-like form. Every few decades to centuries, however, powerful explosions spread ejecta across the landscape. Such explosions can be lethal, as the one in 1790 that killed scores of people in a war party near the summit of Kilauea. Such explosions can take place from either the summit or the upper rift zones. Kilauea has erupted more than 60 times in the past 150 years. The current eruption began in 1983.
