Apo volcano is the highest mountain in the Philippines, and its name means "Master" or "Grandfather". There are no known historic eruptions, but the volcano is considered still active.

Introduction:

Apo volcano is an a basaltic to basaltic-andesitic stratovolcano and part of the Central Mindanao Arc, but its volcanic history is poorly known. The densely forested volcano has a flat summit with 3 peaks, the highest of which in the SW is known as Davao volcano and has a 500 m wide crater with a small lake.
The youngest crater is located on the northern peak. Several fumaroles and sulfur deposits occur on the volcano, most notably fumaroles along a fissure on the SE side down to 2400 m elevation.
The Mt. Apo Geothermal Field is a 8.4 km2 geothermal exploration field near Mt Apo, which has been being exploited since October 1996.

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.

 The sun rises over the great salt lake in the northern Danakil desert, at 130 m below sea level, Africa's lowest point. The purple and orange sky is reflected in patches of water covering hexagonal pieces of salt crust. The lake or salt plain consists of kilometer thick salt sediments that have accumulated over thousands of years in the lowest point of the Rift Valley. They are the result of intense evaporation when the area had been invaded by sea water from the Red Sea. The salt reaches about 4 km maximum thickness. In the background, silhouettes of workers are seen cutting salt blocks out of the crust of the lake. (Photo: Tom Pfeiffer)
