Guatemala and El Salvador - February 12th, 2010

This orthorectified image shows an area around the Guatemala (left) – El Salvador (right) border with many volcanoes and volcanic features. Towards the top, in the upper left quadrant, is Laguna de Ayarza, a crater lake in Guatemala.

The lake is a caldera that was created some 20,000 years ago by a catastropic eruption that destroyed a twinned volcano and blanketed the entire region with a layer of pumice. The lake has a surface area of 14 km² and a maximum depth of 230 m.

East of the lake are first the Tahual, then the Suchitán stratovolcanoes. To its southeast is Volcán de Flores, the most prominent stratovolcano in a volcanic field composed of several small volcanoes. It is located approximately 10 km west of the city of Jutiapa.

Lake Towada (top center) is the largest caldera lake on Honshū island, Japan. It occupies the caldera of an active volcano. Located on the border between Aomori and Akita prefectures, it lies 400 meters (1,800 ft) above sea level and is 327.0m (1,073 ft) depth, and is drained by the Oirase River.

With a surface area of 61.1 km², Towada is Japan’s 12th largest lake, its bright blue color is due to its great depth. The lake is roughly circular, with two peninsulas extending from its southern shore approximately one-third into the center of the lake.

Several volcanoes and caldera lakes can be observed in this orthorectified image of Japan’s Hokkaido island. The largest two lakes are Lake Kussharo (center) and Lake Mashu (right of the former). Prominent volcanoes include Mount Shari, northeast of the lakes, and Mount Mokoto, on the shores of Lake Kussharo.

Mount Shari is a quaternary stratovolcano, located on the Shiretoko Peninsula, with a summit of 1545 m. Nearby peaks include Mount Shibetsu, to the south, and Mount Unabetsu, to the northeast.

Lake Kussharo is a caldera lake in Akan National Park, eastern Hokkaidō. It is the largest caldera lake in Japan in terms of surface area, and sixth largest lake in Japan. It is also the largest lake in Japan to freeze over completely in winter. The lake’s central island, Nakajima, is a composite volcano.

Lake Mashū is a landlocked endorheic crater lake formed in the caldera of a dormant volcano. It is also located in Akan National Park. It has been called the clearest lake in the world.
