Hankow Reef is partially truncated just below the upper left corner of the cloud-covered portion of this NASA Landsat composite image (with north to the top). The possible existence of a now-submerged volcano named Yomba off the coast of Papua New Guinea is inferred from oral tradition and is considered to likely be at the location of Hankow Reef. The reef lies SE of Bagabag Island (upper left) and NW of Long Island, the larger island at the lower right. Crown Island lies beneath the cloud cover between Long Island and Hankow Reef.
