Breakouts on the June 27th lava flow remain active northeast of Puʻu ʻŌʻō. A new, small, breakout appeared recently from the tube adjacent to Puʻu Kahaualeʻa, the small forested cone near the center of the photograph. The new breakout is the light-colored curved flow in the left portion of the photograph. Puʻu ʻŌʻō is in the upper right portion of the photo.

The farthest active breakout on the June 27th flow reached about 8 km (5 miles) northeast of the vent on Puʻu ʻŌʻō. The tip of this breakout was narrow and burning forest. Puʻu ʻŌʻō is at the top of the photograph. Photo taken Thursday, April 23, 2015 courtesy of USGS/HVO

A small breakout from an inflated portion of the June 27th flow. Large gas bubbles reach the surface near the source of the breakout, and are then carried and deformed as the surface advances and cools. Photo taken Thursday, April 23, 2015 courtesy of USGS/HVO

The June 27th flow covers much of the top of the photograph, and recent expansion of the flow margins has sent lava cascading into one of the ponds on the 2007 perched lava channel. This 2007 lava fills the bottom of the photograph, and is covered with yellow alteration. Photo taken Thursday, April 23, 2015 courtesy of USGS/HVO

Over the past week small flows have filled the bottom of Puʻu ʻŌʻō Crater. These flows originated from vents in the south portion of the crater, and one of the flows can be seen near the center of the photograph. Photo taken Thursday, April 23, 2015 courtesy of USGS/HVO

The Overlook crater lava lake, within HalemaÊ»umaÊ»u Crater at KÄ«lauea’s summit, has been rising over the past few days, and Thursday (April 23) reached the highest point yet measured for the current summit eruption. The lava lake in the afternoon was 20 meters (66 feet) below the Overlook crater rim. Photo taken Thursday, April 23, 2015 courtesy of USGS/HVO

Another view of the lava lake, with several areas of spattering active. Photo taken Thursday, April 23, 2015 courtesy of USGS/HVO

The lava level was high enough at the lava lake this evening that bits of spatter were reaching the rim of the Overlook crater. Photo taken Thursday, April 23, 2015 courtesy of USGS/HVO

KÄ«lauea Volcano’s East Rift Zone lava flow continues to feed widespread breakouts northeast of PuÊ»u ʻŌʻō. The front of the breakout farthest downslope was 8 km (5 mi) from PuÊ»u ʻŌʻō on Thursday, April 23.

KÄ«lauea’s summit began to inflate on Tuesday, April 21, and was still inflating as of Thursday. The lava level in the summit lava lake rose in concert, and was 21 m (70 ft) below the rim of the Overlook crater at midday on Thursday, April 23. This is the highest level reached by the lava lake since the summit eruption started in 2008. Seismicity also increased at the summit and along the upper East Rift Zone.

Three earthquakes were reported felt in Hawaii this past week. On Sunday, April 19, 2015, at 7:47 a.m., HST, a magnitude-2.3 earthquake occurred 12.3 km (7.6 mi) southwest Laupāhoehoe, Hawai‘i, at a depth of 16.8 km (10.5 mi). On Monday, April 20, at 9:18 p.m., HST, a magnitude-3.2 earthquake occurred 11.1 km (6.9 mi) NE of Ke‘anae, Maui, at a depth of 14.9 km (9.2 mi). On Tuesday, April 21, at 11:02 p.m., HST, a magnitude-2.4 earthquake occurred 8.0 km (5.0 mi) E of Waiki‘i, Hawai‘i, at a depth of 25.3 km (15.7 mi).

Time-lapse movie from images gathered from a temporary thermal camera looking into Pu’u ‘O’o Crater. The temperature scale is in degrees Celsius up to a maximum of 500 Celsius (932 Fahrenheit) for this camera model, and scales based on the maximum and minimum temperatures within the frame. Thick fume, image pixel size and other factors often result in image temperatures being lower than actual surface temperatures. April 23, 2015. Images courtesy of USGS/HVO

This satellite image was captured on Monday, April 20, 2015 by the Landsat 8 satellite. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures and show active lava. White areas are clouds.
The lava flow field is partly obscured by clouds, but the image shows much of the activity on the June 27th flow. There have been three areas of breakouts active on the June 27th flow recently. The breakout on the north flank of Puʻu ʻŌʻō is obscured by clouds, but the breakout north of Kahaualeʻa is visible through patchy clouds in this image. This breakout has been active recently at the forest boundary, triggering small brush fires. The farthest breakout is about 6 km (4 miles) northeast of Puʻu ʻŌʻō, and consists of scattered activity at the forest boundary.

This map shows recent changes to Kīlauea’s active East Rift Zone lava flow field. The area of the flow on April 9 is shown in pink, while widening and advancement of the flow as of April 23 is shown in red. Puʻu ʻŌʻō lava flows erupted prior to June 27, 2014, are shown in gray.
