Chaac-Camaxtli region

The Chaac-Camaxtli region is a volcanic region on Jupiter's moon Io, located from approximately 5 to 20°N and 130 to 160°W in its anti-Jovian hemisphere.^[1] It consists mainly of the hummocky bright plains that occupy the surface. This area is defined on the west by Chaac Patera, and on the east by Camaxtli Patera.^[1] At least 10 distinct volcanic centers are located in the region, making it a volcanically active region on Io's surface. Most of the volcanism here is expressed as paterae, which range in size from circular to elliptical. A patera is defined by the International Astronomical Union as "irregular or complex craters with scalloped edges.^[2]" The largest volcanic structure here is the Chaac Patera (105 km X 48 km). The paterae found in the Chaac-Camaxtli region are Chaac, Balder Patera, Grannos, Ababinili, Ruaumoko, Steropes, Camaxtli, Tien Mu, Utu, and Mentu.^[1]

This region is full of features that provide clues to the volcanism, tectonism, and magmatic processes on Io. Similar concepts happening on Io have been thought to have occurred in Earth's past, and some terrestrial analogues occur today.
