The leading tip of the June 27th flow has been stalled for several weeks, but scattered breakouts have persisted upslope. On today's overflight, one of these breakouts was active south of the stalled tip and about 650 meters (0.4 miles) northwest of the Pāhoa transfer station.

This comparison of a normal photograph and a thermal image shows the position of active breakouts relative to the inactive flow tip. The white box shows the rough extent of the thermal image on the right. In the thermal image, active breakouts are visible as white and yellow areas.

Another view of the leading portion of the June 27th flow. Persistent breakouts a short distance upslope of the stalled tip have resulted in widening of this section of the flow.

Vog concentrations in Hawai'i are primarily dependent on the amount of SO2 emitted from Kīlauea, the distance from the source vents, and the wind direction and speed on a given day. During trade wind conditions, areas southwest of Kīlauea and the leeward side of Hawai‘i are most frequently affected by vog.

This large-scale map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of Kīlauea's active East Rift Zone lava flow. The area of the flow on February 10 is shown in pink, while widening and advancement of the flow as of February 19 is shown in red.

This map overlays a georegistered mosaic of thermal images collected during a helicopter overflight of the distal part of Kīlauea's active East Rift Zone lava flow on February 19 at about 10:30 AM. The base image is a satellite image acquired in March 2014 (provided by Digital Globe). The perimeter of the flow at that time is outlined in yellow.

The rim of Kīlauea Volcano's summit caldera, normally clear on trade-wind days (left), became nearly obscured by vog (right) on some non-trade wind days beginning in 2008, when sulfur dioxide emissions from the volcano's summit increased to unusually high levels. USGS photos.

The leading tip of the June 27th flow has been stalled roughly 500 meters (550 yards) upslope of Highway 130 for several weeks, but breakouts have persisted upslope of this stalled tip. Today, the closest active breakout to the flow tip was roughly 300 meters (330 yards) upslope of the tip.

Roughly 6 km (4 miles) upslope of the stalled tip of the flow, a small breakout was active at a major fork on the June 27th flow. The lobe extending off the top of the photograph entered Pāhoa in October, and is now inactive. The lobe extending off the left edge of the photograph is the currently active lobe.

A breakout was also active farther upslope, closer to Pu‘u ‘Ō‘ō. This breakout, visible as the light gray surface, has reached the forest boundary and triggered several small brush fires.

The summit lava lake in Halema‘uma‘u Crater continues with relatively steady activity. Today, spattering was active along the south margin of the lava lake.
