The June 26 breakout continues to advance across the coastal plain. Today, July 21, the front of this breakout was approximately 350 m (0.2 miles) wide, and roughly 2 km (1.2 miles) from the closest points in the emergency access road. The eastern side of the flow front was outside of the Hawaii Volcanoes National Park boundary, and there were many scattered sluggish pāhoehoe breakouts (pictured above). The western side, inside of the National Park, had less active pāhoehoe breakouts.

The Kamokuna ocean entry and lava delta remain active, with no obvious changes over the past week. The large coast-parallel crack that spans the width of the delta (seen from lower-left to upper-right of image) remains prominent, and highlights the instability of the delta.
