Kawah Ratu - Mt. Tangkuban Perahu, West Java, Indonesia

Mt. Tangkuban Perahu is Bandung's most famous volcano just 28 km north of the city. This volcano has a distinctive shape, like an upside down boat (Tangkuban Perahu means, in fact, "up-turned boat"), it  has three craters into which areas tourists can walk through. These three craters are: Kawah Ratu, Kawah Domas and Kawah Upas.
Kawah Ratu, which means "Queen's Crater", is today just a big gray hole, which sometimes has a pool of water at its center. Poisonous gases sometimes accumulate in Kawah Ratu, thus making it somewhat of a risk to descend to the crater floor. Beyond the saddled shaped depression on the far side of Kawah Ratu is the still active Kawah Upas, the oldest crater on the mountain. On the very far western cliff we see a spot where all vegetation has been destroyed by constantly rising sulfurous vapors. On the crater walls, note the various layers of material consisting of rock, sand, and pebbles. Overtime, new craters have formed again and again in a rather consistent shift from west to east.

Agios Nikolaos chapel on Palea Kameni island, one of the two historic volcanic islands in the center of the Santorini caldera (Greece). The sea around the island with its small bays is a popular destination for boat cruises - swimmers enjoy the warm waters of the red iron bay.
The orange stain of the rocks on the shore is the result of iron oxide deposit from an active hydrothermal vent system at the shallow sea floor around the Kameni islands. It releases heated, iron-rich waters and deposits a layer of iron-mud on the sea floor. (Photo: Tom Pfeiffer)
