From today's daily update (http://hvo.wr.usgs.gov/activity/kilaueastatus.php)
Note: Recent seismicity in the caldera of Kilauea has been elevated over the last 6 days with several Long Period (LP) and Very Long Period (VLP) earthquakes. Locating earthquakes of this type is particularly difficult, and thus our earthquake maps show a spread in locations around the caldera that does not reflect the location of the actual sources. Based on detailed studies of this type of event, we expect that most of these earthquakes are associated with the shallow conduit under Halema`uma`u. The occurrence of earthquakes of this type and number are often associated with high lava-lake levels and likely reflect high pressures in the summit caldera. The deformation data suggest a deflation source within the caldera that is slightly north from the usual DI tilt event source which may be an actual location or the result of combined processes around that location; however, the nature of the process is still uncertain.
