KILAUEA VOLCANO (CAVW#1302-01-)
19.43°N 155.29°W, Summit Elevation 4009 ft (1222 m)
Volcano Alert Level: WATCH
Aviation Color Code: ORANGE
Report prepared by the Hawaiian Volcano Observatory (HVO):
Activity at Kilauea Volcano has not changed significantly at the summit or east rift zone since 6 a.m. The summit shows only slight inflation; the tremor levels continue to decrease. Fewer than about 10 small earthquakes per hour are being recorded in the upper east rift zone, and the tremor levels have decreased slowly since Tuesday afternoon; only two earthquakes were large enough to locate. Occasional bursts of tremor continue to occur in the Kane Nui o Hamo area.
The webcam on the rim of Pu`u `O`o crater is showing only steam beyond the crater rim. A tiltmeter continues to indicate steady collapse of the cone. No views were possible during this morning's overflight due to intense steam.
HVO has scheduled another overflight for this afternoon, and continues to monitor the situation closely. Gas measurements were made but were not yet reduced by update time. Weather permitting, additional gas measurements will be made at the summit and along the east rift zone later today.
