Mud Volcano from Aloft
March 02, 2017
Shown above is a mud volcano as viewed from overhead near the village of Wringinanom-Sumberwaru, Indonesia. The flow material is actually mud mixed with saltwater and gas. The crater from which the mud erupts, at center, is called a crewek -- mud spreads out laterally from cracks. Note that the flow here is ephemeral. It only occurs during the wet season, from about November to March. At upper right shoring erected to protect fields adjacent to the crater can be seen. Photo taken at an altitude of 545 ft (166.2 m) (altitude), by a DJI Drone, on January 28, 2017.
