Kilauea Daily Update issued Sep 4, 2007 08:44 HST Volcanic-Alert Level WATCH – Aviation Color Code ORANGE
Report prepared by the Hawaiian Volcano Observatory (HVO):

Activity Summary: The 7/21 fissure eruption continued to supply an open channel which, in turn, fed two `a`a flows – one advancing to the northeast over previous flows and the other advancing along the southern margin of previous flows. The summit and Pu`u `O`o recorded the inflation portion of a DI (deflation-inflation) tilt event starting mid-afternoon yesterday.

Hazard Summary: There are no immediate threats directly from lava flows. A publication detailing the current and potential future hazards posed by this eruption is available at http://pubs.usgs.gov/of/2007/1264/.

Vent areas are hazardous and conditions can change rapidly. Access to the 7/21 eruption site in the Kahauale`a Natural Area Reserve is closed (see http://www.state.hi.us/dlnr/chair/pio/HtmlNR/07-N076.htm). Lava flows advancing through vegetation are hazardous and can produce fire and methane explosions that propel chunks of lava and rock several feet into the air.

last 24 hours at 7/21 eruption site: The vent continues to supply an active lava channel about 1 km long. Two flows issue from the lower end of that channel: a spillover fed an `a`a flow moving northeast and 2-3 seeps on the south side fed an `a`a flow advancing along the southern margin of previous flows. The lower section of channel overflowed infrequently.

last 24 hours at Pu`u `O`o crater: The webcam again showed lots of fume but no incandescence. The tiltmeter on the north flank of Pu`u `O`o cone turned around and recorded slow inflation about 1.5 hours after an abrupt tilt reversal at Kilauea summit. Seismic tremor levels are at low values except beneath Pu`u `O`o where the levels are at moderate values. Rockfall seismic signals have decreased in frequency since yesterday afternoon.

last 24 hours at Kilauea summit: The tilt network recorded the expected abrupt inflation starting at 3:10 pm. Seismic tremor levels have returned to low values. A few small deeper earthquakes were located beneath the southwest rift zone and the south flank.
