Several large surface lava flows from the eruption along Kīlauea's east rift zone occurred this past week. The largest of these flowed down the east side of the flow field between the Kamoamoa flows and those that surrounded Waha'ula several years ago.

The eruption along Kīlauea's East Rift Zone continues with little change since our last report in mid-June. There are still two erupting vents located on the southwest and west flanks of the Pu'u 'O'o cone, which is located about 11 miles east of Kīlauea's summit.
