Hello Lela; Those are aftershocks from a tectonic (not volcanic) M6.4 that happened near Tanaga. Hope this helps, Cheryl -------- Lela Criswell wrote: I've been watching the Little Sitkin webicorder for the past few weeks while it's been on yellow status, and looking at others in that same area of the Aleutians. On the 28th and 29th there were MANY small earthquakes on the Tanaga webicorder, way more than on Little Sitkin. Today they are not as east to see as there is obviously some weather event showing up on both Kanaga and Tanaga, but there are still many of them there. If this were Gareloi I would think it was normal, but it's different for Tanaga. What's going on? -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
