Angry Pavlof continues to belch out ash, gas and steam
PAVLOF VOLCANO (CAVW #1102-03-)
55°25’2″ N 161°53’37” W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Ash, gas and steam emissions continue at Pavlof Volcano, as seismic tremors and intense elevated surface temperatures persist, AVO reported.

KILAUEA VOLCANO (CAVW #1302-01-)
19°25’16” N 155°17’13” W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Activity Summary: At the summit, tiltmeters recorded the start of DI inflationary tilt and the lava lake level rose. At Pu`u `O`o vent in the middle east rift zone, there was no new activity within the crater but the Kahauale`a II lava flow remained active on the north base of the cone. To the southeast, the Peace Day pali flow remained active on the coastal plain while the main flow branch continued to enter the ocean in at least 2 locations spanning the Hawai`i Volcanoes National Park boundary. Gas emissions remained elevated. (HVO)
Recent Observations at the middle east rift zone vents: Only glow was seen from the east lava pond and spatter cones on the crater floor. The tiltmeter on the north flank of Pu`u `O`o cone recorded the start of DI inflationary tilt at 8 pm yesterday. GPS receivers on the north rim and south base of Pu`u `O`o cone recorded neither extension nor contraction since May 12. The most recent (preliminary) sulfur dioxide emission rate measurement was 300 tonnes/day on April 26, 2013, from all east rift zone sources; these values have ranged between 150 and 450 t/d in 2013; these measurements are made at a greater distance from the sources where the plume is more easily characterized.

VONA/KVERT DAILY REPORT – May 17, 2013
Kamchatkan and Northern Kuriles Volcanic Activity
SHEVELUCH VOLCANO (CAVW #1000-27-)
56.64 N, 161.32 E; Elevation 10768 ft (3,283 m), the dome elevation ~8200 ft (2500 m)
Aviation Color Code is ORANGE
Moderate seismic activity continues at the volcano. Video images showed a moderate gas-steam eruption and incandescence above the lava dome. Satellite data showed a thermal anomaly over the volcano.
PLOSKY TOLBACHIK VOLCANO (CAVW #1000-24-)
55.83 N, 160.39 E; Elevation 10119 ft (3085 m)
Aviation Color Code is ORANGE
Strong seismicity occurring at the volcano. The amplitude of volcanic tremor was up to 3.2 mcm/s. Explosive-effusive eruption continues: lava continues to effuse from the Southern fissure on Tolbachinsky Dol. A thermal anomaly was noted on satellite images at the northern area of Tolbachinsky Dol.
KIZIMEN VOLCANO (CAVW #1000-23-)
55.13 N, 160.32 E; Elevation 8151 ft (2485 m)
Aviation Color Code is ORANGE
Moderate seismic activity continues at Kizimen. Video images showed growth of an extrusion at the volcano summit continues. Incandescence of the volcano summit, hot avalanches on the western and eastern volcanic flanks, and strong and moderate gas-steam activity accompany this process. Satellite data showed the volcano was obscured by clouds.
KARYMSKY VOLCANO (CAVW #1000-13-)
54.05 N, 159.44 E; Elevation 4874 ft (1486 m)
Aviation Color Code is ORANGE
There was no seismic data due to technical reasons. Satellite images were obscured by clouds.
BEZYMIANNY VOLCANO (CAVW #1000-25-)
55.97 N, 160.6 E; Elevation 9453 ft (2882 m)
Aviation Color Code is YELLOW
Strong seismic activity at Tolbachinsky Dol obscured seismicity of Bezymianny. WebCam images obscured by clouds. Satellite data showed a thermal anomaly over the volcano.
GORELY VOLCANO (CAVW #1000-07-)
52.56 N, 158.03 E; Elevation 5996 ft (1828 m)
Aviation Color Code is YELLOW
Moderate seismic activity continues at Gorely. Volcano was obscured by clouds.
