Peru Volcano Prompts Evacuations

A volcano in southwestern Peru called Ubinas began ejecting pyroclastic material into the sky in 2006, after over four decades of lying dormant. Recent volcanic activity has prompted officials to evacuate 60 residents of Querapi, a village near its base. The last state of emergency due to Ubinas activity occurred on April 23, 2006. Ubinas town mayor Pascual Coaquira said …

Tunnels Under Rome Being Mapped to Prevent Further Damage to City

An extensive series of ancient tunnels and quarries under Rome are threatening parts of the city that has been built atop them. Many years ago, Rome’s earliest architects discovered that tuff, or rock made of consolidated volcanic ash, was a perfect building material. It was strong, yet easily carved into blocks. The soil beneath Rome was layered atop this tuff, …

Mount Etna Erupts, Peppers Towns with Ash

Europe’s most active volcano, Mount Etna, erupted Saturday, showering pyroclastic detritus on towns around the mountain’s slopes and the nearby comune of Taormina. The eruption didn’t call for any evacuations, though an area highway was shut down for 30 minutes, as a safety measure. Air traffic was also restricted in four air corridors around nearby Catania Airport. Mount Etna is …

Earthquake In Greece, Magnitude Over 6

Crete, in the southern part of Greece, was the recent site of an earthquake that measured a magnitude of greater than six on the Richter scale, which uses seismic energy to determine the actual amplitude or motion of the ground. There is some reported variation in the exact strength of the earthquake. According to the US Geological Survey, the specific …

Water Found on Moon’s Surface, More Could be Below

Researchers from the Indian Space Research Organization this week have announced that the Chandrayaan-1 probe has founde evidence for water on the surface of the Earth’s moon. The water, referred to as “magmatic,” is locked in mineral grains and could come from somewhere beneath the moon’s surface. The new research, published recently in the journal Nature Geoscience, is the first …

Charles Darwin Wrong About Coral Atolls, Shows Study

Though Charles Darwin is known as the father of modern biology, evolutionary biologists are well aware that he got many aspects of evolution wrong. In particular, with no knowledge of genetics Darwin was left to speculate heavily on the mechanisms of evolutionary change. Now, geologists have discovered another hypothesis on which Darwin was not entirely right. According to a LiveScience …

Earth Permanently Deformed After Earthquakes in Chile, Shows Study

A new study by geologists at Cornell University has shown that earthquakes can leave the Earth deformed. Cornell geologist Richard Allmendinger told LiveScience that strong earthquakes in Chile have left permanent cracks in the surface of the Earth. The findings “perplexed” Allmendinger and his colleagues, as the Earth is known to “rebound” after earthquakes – an effect that is chronicled …

Earthquakes Turn Water to Gold, Shows New Study

One of the major goals of alchemy was to create gold from other, less expensive materials. Now it appears that if alchemists of old could have harnessed the power of the Earth, they might have been successful. A new study has shown that earthquakes can play a role in turning water into gold. Sort of. The study, published in this …

Oahu Dissolving Into the Pacific, Shows Study

Oahu, the third largest of the Hawaiian Islands and the home of Honolulu, is dissolving from the inside, shows a new study. Geologists state that the island’s Koolau and Waianae mountains will gradually be reduced to nothing, leaving Oahu a flat, low-lying island. “We tried to figure out how fast the island is going away and what the influence of …

Mars Once Had Warm Water, Study Reveals

New research on Martian meteorites shows evidence that water sufficiently warm enough to support life once existed on Mars. The study, published this week in the journal Earth and Planetary Science Letters, determined that water temperatures on Mars ranged from 50°C (122°F) to 150°C (302°F). This observation was made using powerful electron microscopes to examine meteorites from Mars that have …

Mars Rover Curiosity Finds Surprises on Mars

Just after the Mars rover Curiosity completed its first scoop of Martian soil, project leaders halted the testing process when a small piece of unknown junk was found in one of the pictures. It turns out the refuse is harmless, and NASA’s Jet Propulsion Laboratory this week resumed the soil testing process, which involved vibrating the sample “vigorously” to clean …

Mars Rover Curiosity Finds Ancient Streambed on Mars

While much of the excitement surrounding the landing of NASA’s newest rover on Mars was about the thrill of interplanetary exploration or the prospect of finding life on the red planet, many of the discoveries uncovered by the Curiosity rover are most likely to be of interest to Geologists. Today, for example, NASA announced that Curiosity has found evidence of …
