Katmai National Park and Preserve, Alaska. Volcanic detritus deposit is 3 feet thick on the north end of Takli Island in Amalik Bay. The detritus is probably thicker on the mainland shown in the background. The white bands on the water are of floating pumice. The dark area in the left foreground is clear water. The white streaks on the beach are fine pumice. The rocks are tertiary basalt. August 8, 1912. Photos mgc00625, mgc00626, and mgc00627 form a panorama.

Guatemala Earthquake 1976. A suggested model showing combined relative movement between the North American (green), Cocos (blue), and Caribbean (yellow and orange) plates and within the Caribbean plate to account for the complex tectonics of northern Middle America. Predominantly extensional faulting (blue zones) has caused fragmentation of the western part of the Caribbean plate. As a consequence, the northern part of the plate (yellow) may be decoupling from the southern part (orange) along the major northwest- southeast trending system of graben that follows the volcanoes (black dots) of the Middle America arc. White arrows show directions and relative amounts of long term movements of the plates and plate fragments;...
