Lava continues to erupt from the TEB vent on Kilauea’s east rift zone and flow through tubes to the ocean at Waikupanaha.  

A small lava breakout on the rootless shield complex was active for a few days this week, but has now stagnated.  

A lava breakout from the tube near the top of the Royal Gardens subdivision has been active throughout the past week. 

The flows are mostly staying close to the breakout point and are building a broad shield-shaped mound of lava.

Faint glow above the vent at Kilauea’s summit has been visible at night.  Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.

Two earthquakes beneath Hawaii Island were reported felt this past week. 

A magnitude-2.5 earthquake occurred at 5:56 a.m. Monday, Sept. 21, 2009, and was located 6 miles northeast of Waikii at a depth of 16 miles. 

A magnitude-2.3 earthquake occurred at 7:28 a.m. the same day and was located in the same area at a depth of 16 miles.
