In the lower east rift zone activity continues with little change.  Lava from the fissure eight fountain continues to reach heights of about 175 feet as measured during the overnight hours. The lava pulses sending a shower of hot lava fragments over the rim of the cinder cone building it slightly higher and wider.  The lava exits fissure eight traveling at a rate of about seventeen miles per hour.  It slows down significantly toward the quarry to about two miles an hour and significantly less than that at the ocean entry. At the ocean entry lava is entering in the southern part near the vicinity of Vacationland producing a robust steam and laze plume.  The lava has now created a lava delta in seaward that is approximately 380 acres in size.

Up at the summit, subsidence continues with the withdrawal of magma at depth.  The popular overlook parking area has now slumped into the crater.  This area was closed since 2008.  Earlier this week crews installed temporary GPS stations to track the rate of subsidence at the caldera and today a UAS team a drone team will be up trying to take pictures, weather permitting, of the changes that have occurred in the summit to produce digital elevation models that will help characterize and track the extensive subsidence.  This is the video update for Thursday June 21st.
