Sanford reported activity



Event Name : Sanford 2010/3

Start:March 15, 2010 Observed
Stop:October 20, 2010 Observed

Meterologic clouds - no eruption: BibCard
Eruption Type:Not an eruption.
Duration: 2 occurrences of meterologic vapor plumes: March and October BibCard

Description: From Neal and others (2014): "On March 23, a consulting geologist working in the area reported seeing a 'good size plume' from Sanford on 2 night. A number of Copper River Valley residents shared photographs of Sanford from March 15 when a dramatic looking plume emated from the southern flank and summit of the volcano.

"A similar cloud was reported on October 20 by Pete Dalton, District Ranger for the National Park Service, stationed at the Gulkana Airport. According to Pete Dalton, the plume rose about 2000 to 3000 ft above the summit. AVO received multiple calls regarding the October 20 plume, which appeared to originate from several points on the near-vertical, rocky southern face of the volcano. A towering vapor cloud emanating from the steep rocky face of this volcano has been reported before (McGimsey and others, 1999) and may be related to rock and ice-fall activity, solar warming of the rock and ice face, or a combination of processes. No features related to volcanic heat sources have been documented on Mount Sanford; however, no comprehensive thermal survey has been done."
