Another view of the narrow flow front. Kaohe Homesteads is in the lower left portion of the image. The vent for the June 27th lava flow is on Pu‘u ‘Ō‘ō, which can be seen on the skyline.

Views of the flow front from two different angles, with equivalent thermal images for comparison. The thermal images show that surface breakouts were focused on three areas near the flow front: 1) the flow front itself, 2) an area 300 meters (yards) behind the flow front and 3) a larger area about 1 km (0.6 miles) behind the flow front.

This map uses satellite imagery acquired in March 2014 as a base image to show the area around the front of the June 27th lava flow. The blue line and arrowheads show the projected path of the flow over the next two weeks (to October 3), based on the average flow rate over the last two days and the local topography.

A closer look at the lava lake at Kīlauea's summit. The lake was roughly 53 m (170 ft) below the floor of Halema‘uma‘u Crater this morning.

Another view of the flow front in the northwest portion of Kaohe Homesteads. The leading portion of the flow front narrowed over the past two days and was roughly 150 m (500 ft) wide.

A close-up view of the flow surface near the flow front, which consisted of numerous, scattered small pāhoehoe lobes.

This small-scale map shows the June 27th flow in Kīlauea's East Rift Zone in relation to lower Puna. The area of the flow on September 15, 2014, at 2:00 PM is shown in pink, while advancement of the flow as mapped on September 17 at 3:45 PM is shown in red.

A view of the leading tip of the flow, which was moving through thick forest.

This large-scale map shows the distal part of the June 27th flow in relation to nearby Puna communities. The black dots mark the flow front on specific dates. The latitude and longitude of the flow front on September 17 was 19.4737016 /-154.977834 (Decimal degrees; WGS84).

The June 27th lava flow remains active and continues advancing northeast in the forested, northwest portion of Kaohe Homesteads. The flow front today was 2.7 km (1.7 miles) from Apa‘a st. and 3.8 km (2.3 miles) from Pāhoa Village Road. Over past two days, the flow front has advanced at an average rate of 290 m/day (960 ft/day).

The summit eruption continues, with an active lava lake within Halema‘uma‘u Crater. Halema‘uma‘u fills up most of the image, and the lava lake can be seen near the bottom of the image contained within the smaller Overlook crater.

This large-scale map shows the distal part of the June 27th flow in relation to nearby Puna communities. The black dots mark the flow front on specific dates. The latitude and longitude of the flow front on September 15 was 19.469506 /-154.981172 (Decimal degrees; WGS84).

USGS researcher Jeff Wynn monitors in-coming data at the CSAMT (Controlled-Source Audio-Magnetotellurics ) receiver site on Mount St. Helens. The data will be used to locate the top of the groundwater system beneath the site.

The June 27th lava flow remains active and continues advancing towards the northeast. Recently, the flow front entered the Kaohe Homesteads subdivision, and is currently within the vacant, forested northwest portion of the subdivision. The flow front was 3.3 km (2.1 miles) upslope from Apa‘a Road and 4.3 km (2.7 miles) from Pāhoa Village Road.

A closer view of surface activity on the June 27th lava flow. This pāhoehoe flow consists of many small, scattered, slow-moving lobes burning vegetation.

HVO geologists conduct a VLF (very-low frequency) survey to measure the rate of lava flowing through the lava tube on the June 27th lava flow.
