AVO VOLCANO ACTIVITY NOTIFICATION
(1) VOLCANO OBSERVATORY NOTICE FOR AVIATION (VONA)
(2) Issued: (20130513/1938Z)
(3) Volcano: Pavlof (VNUM #312030)
(4) Current Color Code: ORANGE
(5) Previous Color Code:
(6) Source: Alaska Volcano Observatory
(7) Notice Number: 2013/A9
(8) Volcano Location: N 55 deg 25 min W 161 deg 53 min
(9) Area: Alaska Peninsula
(10) Summit Elevation: 8261 ft (2518 m)
(11) Volcanic Activity Summary: Seismic activity at Pavlof Volcano increased this morning commensurate with the presence of an intense thermal anomaly at the summit observed in latest satellite imagery. Similar patterns of seismicity and elevated surface temperatures have previously signaled the onset of eruptive activity at Pavlof. Although not yet visually confirmed, a low-level eruption of lava has likely begun from a summit vent. No ash clouds have been detected.
(12) Volcanic cloud height: Unknown
(13) Other volcanic cloud information: Unknown
(14) Remarks: Pavlof volcano is located on the southwestern end of the Alaska Peninsula. Pavlof is a stratovolcano which rises to an elevation of 8262 feet. With almost 40 historic eruptions, it is one of the most consistently active volcanos in the Aleutian arc. Eruptive activity is generally characterized by sporadic strombolian fountaining continuing for a several-month period. The community of Cold Bay is located 60 km (37 miles) to the southwest of Pavlof. The last eruption occurred in August 2007.
