(1) VOLCANO OBSERVATORY NOTICE FOR AVIATION (VONA)
(2) Issued:	(20141126/0027Z)
(3) Volcano:	Pavlof (VNUM #312030)
(4) Current Color Code:	YELLOW
(5) Previous Color Code:	ORANGE
(6) Source:	Alaska Volcano Observatory
(7) Notice Number:	2014/A19
(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:	The most recent period of explosive eruptive activity at Pavlof Volcano has ended. For about the past week, seismicity at the volcano has remained at low levels and shows no indication of the unrest typically associated with lava fountaining or ash emission. Satellite observations show no evidence for continuing eruptive activity. Thermal signals at the summit are occasionally visible, but are likely being generated by the cooling of previously emplaced lava and debris and not newly erupted material. The low levels of seismic activity and the lack of evidence for continued lava effusion indicate that the brief eruption has ended and thus AVO is lowering the Aviation color code and Volcano Alert Level to YELLOW/ADVISORY. Pauses in vigorous eruptive activity of days to weeks are common during eruptive episodes of Pavlof Volcano. A return to more robust eruptive activity remains possible and could occur with little or no warning. Thus, AVO will continue to monitor the volcano closely and will issue additional information as necessary.
