Photo Gallery


Sinarka is the northernmost of two volcanoes forming Shiashkotan Island that are connected by a narrow isthmus about 1 km wide (out of view to the bottom). This Space Shuttle image (with north to the upper left) shows the complex summit region of the volcano. Historical eruptions have occurred at Sinarka during the 17th and 18th centuries. The last and largest of these, during 1872-78, was once thought to originate from Kuntomintar volcano at the southern end of Shiashkotan.
