Wushanting Mud Volcano, Kaohsiung Prefecture, Taiwan

 Groundwater, mud, hydrocarbon gas, and oil erupt intermittently from the top of the gryphons. The highest gryphon is about 8 m high. These are located at the crest of the mountain along the Chishan Fault, which runs northeast to southwest. Several gryphons can be found in an area of 200 m × 200 m.
