Following the Turks and Caicos, the next map in this tour of subtropical areas would be between 20 and 30 degrees South and 63 and 72 degrees East. There is no land or shallow marine area within these coordinates. The sea floor at this location is where the Somali Plate, Capricorn Plate, and Antarctic Plate join. The plate boundary between the Capricorn and Somali plates is the Mid-Indian Ridge, while the boundary between the Somali and Antarctic is the Southwest Indian Ridge.
Next series: 10 to 20 degrees; 60 degrees. This includes portions of Oman, Mauritius, Bolivia, and the eastern Caribbean.
