52°22'46" N 174°9'17" W, Summit Elevation 5030 ft (1533 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN
AVO is lowering the Aviation Color Code to GREEN
, and the Volcanic Activity Alert Level to Normal at Korovin. The volcano has been at Color Code YELLOW
and Alert Level Advisory since November 6, 2006. Over the last several months, seismicity rates have declined to near background levels. Recent satellite data also indicate that ground deformation at Korovin has slowed markedly, and perhaps ceased altogether, after a period of uplift from approximately mid-summer 2006 through early-spring 2007.
Steam emissions from Korovin and occasional bursts of low-level earthquakes or volcanic tremor will likely still occur, but both of these phenomena are typical of background activity for this volcano, which has a long-lived, well-developed hydrothermal system.
