"At 29,029 feet above sea level, Mount Everest is the highest mountain in the world. But despite Everest's massive peak, Chimborazo in the Ecuadorean Andes is the farthest point from the center of the earth.

No slouch in the size department, Chimborazo is actually an inactive volcano that stands at 20,565 feet. It makes up for the 9,000 foot difference between itself and Everest with the equatorial bulge. Only one degree south of the equator, the earth is thicker nearer the equator, and makes up the extra difference for Chimborazo. When all is said and done, Chimborazo measures 7,113 feet farther from the center of the earth than Mount Everest and is a whopping 3,967 miles from earth's center."

"I photographed this beautiful cinder cone while touring the area north of Flagstaff, Arizona, in March and April 2010. It forms a striking pose looking over the surrounding grassy plains. The area that includes this cone and the more famous Sunset Crater is known as the San Francisco Volcanic Field. Eruptions in this field between the years 1040 and 1100 would have profoundly affected the way of life of the local inhabitants who witnessed these powerful geologic processes."

"Dallol is a volcanic explosion crater (or maar) in the Danakil Depression, northeast of the Erta Ale Range in Ethiopia. It has been formed by the intrusion of basaltic magma in Miocene salt deposits and subsequent hydrothermal activity. Phreatic eruptions take place here, the last known one in 1926, numerous other eruption craters dot the salt flats nearby. These craters are the lowest known subaerial volcanic vents in the world, at over 45 m (150 ft) below sea level." Wikipedia

A cloud of lightning-topped ash rises toward a starry sky during the June eruption of southern Chile's Puyehue-Cordón Caulle volcano complex in a picture submitted to My Shot in October. The summer eruption grounded flights in Chile and neighboring Argentina.

This month officials began evacuating people from the immediate vicinity of the Hudson Volcano, 470 miles (756 kilometers) south of Puyehue-Cordón Caulle, according to the Associated Press. Recent releases of steam and ash from the volcano have had authorities in Chile and Argentina on high alert, AP reports.

The latest image released from Mars Express reveals a large extinct volcano that has been battered and deformed over the aeons.

By Earthly standards, Tharsis Tholus is a giant, towering 8 km above the surrounding terrain, with a base stretching over 155 x 125 km. Yet on Mars, it is just an average-sized volcano. What marks it out as unusual is its battered condition.

Shown here in images taken by the HRSC high-resolution stereo camera on ESA's Mars Express spacecraft, the volcanic edifice has been marked by dramatic events.

This article will examine ten geological discoveries that have made headlines in the scientific world. The events have all occurred in the last 15,000 years, which is recent in terms of the geologic time scale.

"The largest known rock transported by the Missoula Floods is pictured, located on the Ephrata Fan, near Soap Lake, Washington...."The water flow was nine cubic miles per hour, more than ten times the combined flow of every river in the world. Maximum discharge was about 1.3 billion gallons per second, about 1,000 times the Columbia River’s current average flow."...

Mount Teide's Triangular Shadow over Pico Viejo Crater

"Why does the shadow of this volcano look like a triangle? The Mount Teide volcano itself does not have the strictly pyramidal shape that its geometric shadow might suggest. The triangle shadow phenomena is not unique to the Mt. Teide, though, and is commonly seen from the tops of other large mountains and volcanoes. A key reason for the strange dark shape is that the observer is looking down the long corridor of a sunset (or sunrise) shadow that extends to the horizon. Even if the huge volcano was a perfect cube and the resulting shadow was a long rectangular box, that box would appear to taper off at its top as its shadow extended far into the distance, just as parallel train tracks do. The above spectacular image shows Pico Viejo crater in the foreground, located on Tenerife in the Canary Islands of Spain. The nearly full moon is seen nearby shortly after its total lunar eclipse last month."

"Spanning about 22 kilometers (14 miles), Valles Caldera in New Mexico was formed from the collapse of a magma chamber following ancient volcanic eruptions. The Enhanced Thematic Mapper Plus on Landsat 7 satellite captured this natural-color image of the area on May 22, 2002. Plants have colonized parts of the caldera, which is surrounded by a network of valleys. The city of Los Alamos lies to the east."
