Good morning everyone Kīlauea is still erupting at two locations today at the summit and in the lower east rift zone.  The summit has been pretty active there’s been over 300 earthquakes in the past 48 hours and at least a dozen earthquakes that have been between magnitudes three and four yesterday the largest was a magnitude four.  The earthquakes are occurring as a result of continued subsidence at the summit and we have seen five feet of down dropping at the summit just around the Halemaʻumaʻu crater area. The deflation is also causing rock falls, there’s more ash plumes that are going up into, up above sea level to like above 10,000 feet.  So, three of those occurred yesterday and we are keeping an eye on that, there have been lots of smaller explosions from the summit as well.  Moving down to the lower east rift zone lava flows continue to erupt from the central fissure complex right around the eastern edge of the Leilani Estates neighborhood.  Fissure eight became reactivated overnight, but the primary activity has been around the fissure seven and twenty-one area and there’s also two channels of lava that are still issuing down to the coast and there are two ocean entries.  The ocean entry that is furthest to the west looks like it might be starting to form a lava tube system and we’re going to keep a close eye on that. That’s the update of today.
