Breakouts continue northeast of PuÊ»u ʻŌʻŠin three main areas: 1) at the northern base of PuÊ»u ʻŌʻŠcone, 2) north of PuÊ»u KahaualeÊ»a and 3) about 6 km (4 miles) northeast of PuÊ»u ʻŌʻÅ. This photograph looks east and shows the breakout about 6 km from PuÊ»u ʻŌʻÅ. This breakout consists of several narrow lobes that have expanded the June 27th lava flow margin by a minor amount, with a small amount of vegetation burning.

A closer look at the leading tip of the farthest downslope breakout. The tip of the breakout was burning forest, and was 6.9 km (4.3 miles) northeast of the June 27th vent on PuÊ»u ʻŌʻÅ. Photo taken Thursday, April 9, 2015 courtesy of USGS/HVO
This photograph looks upslope and shows another narrow lobe on the breakout that is roughly 6 km (4 miles) northeast of PuÊ»u ʻŌʻÅ. This lobe was moving along the south margin of the June 27th flow. Photo taken Thursday, April 9, 2015 courtesy of USGS/HVO

KÄ«lauea’s East Rift Zone lava flow continues to feed three areas of breakouts near PuÊ»u ʻŌʻÅ. The front of the breakout farthest downslope had advanced very little over the past week and was still about 7 km (just over 4 mi) northeast of PuÊ»u ʻŌʻŠwhen mapped on Thursday, April 9.
There have been no major changes at KÄ«lauea’s summit vent, which continues to host an active lava lake. The lava lake level continues to fluctuate and was 37 m (120 ft) below the rim of the Overlook crater on April 9.
There were two earthquakes reported felt on the Island of Hawai’i in the past week. On Sunday, April 5, at 12:16 a.m. HST, a magnitude-3.3 earthquake occurred and was located 10.6 km (6.6 mi) northeast of Kawaihae at a depth of 25.8 km (16.0 mi). On the same day at 3:23 a.m. HST, a magnitude-4.5 earthquake occurred and was located 6.3 km (10.1 mi) northwest of Kailua at a depth of 10.0 km (6.2 mi).

This map shows recent changes to KÄ«lauea’s active East Rift Zone lava flow field. The area of the flow on April 3 is shown in pink, while widening and advancement of the flow as of April 9 is shown in red. We were not able to map some parts of the flow field with breakouts today due to poor weather, and these areas are denoted in boxes. Neither area has changed significantly since our previous mapping. See the map posted on April 1 to see the entire June 27th lava flow field and location of PÄhoa.
