Roundup of Global Volcanic Activity

Kilauea (Hawai'i): After a week of many changes here on Kilauea, summit tilemeters recorded slowing inflationary tilt. The summit tiltmeters recorded the start of inflationary tilt at 6:30pm on Saturday May 17th - this suggests that the unusual deflationary tilt recorded since May 10 may have been a DI tilt event that totaled almost 8 microradians before the tilt switched. Because of this deflationary tilt the lava lake dropped around 20m (65ft) is has stabilized at 58m (191ft) below the floor of Halema'uma'u crater. There were 3 days last week that over 100 earthquakes were recorded at the summit of Kilauea each day! Along the East Rift Zone at Pu'u 'O'o minimal activity was recorded. Most of the flows on the crater floor stopped or slowed, however over the past 48 hours the activity to the Northeast and South of the cinder cone gained momentum.
