(1) VOLCANO OBSERVATORY NOTICE FOR AVIATION (VONA)
(2) Issued:	(20160520/1935Z)
(3) Volcano:	Pavlof (VNUM #312030)
(4) Current Color Code:	YELLOW
(5) Previous Color Code:	ORANGE
(6) Source:	Alaska Volcano Observatory
(7) Notice Number:	2016/A11
(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 recent period of eruptive activity at Pavlof Volcano that began on May 13, 2016 has ended. Minor ash emissions were last observed on May 16. Since then, we have not detected seismic signals associated with ash emission or lava effusion. Satellite observations show no evidence for eruptive activity. Thus AVO is lowering the Aviation color code and Volcano Alert Level to YELLOW/ADVISORY. The volcano remains in a heightened state of unrest. Pauses in eruptive activity of days to weeks are common during eruptive episodes of Pavlof Volcano. A return to 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.
(12) Volcanic cloud height:	Not detected or observed.
(13) Other volcanic cloud information:	No ash emissions detected or observed since May 16, 2016.
