The 54-km-long and up to 6.5-km-wide San Jorge island is shown across this December 2018 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 27 km across). The island has three main parts that compose the upper units across the island, with the Rosais Complex to the W, the Manadas Complex in the center, and the Topo complex in the E. The western two-thirds (mostly shown here) has fissure vents across the surface that produced lava flows and spatter ramparts.
