Huge 250 meter tsunami struck Asia 70,000 years ago. Could it happen again?

The tsunami that inundated Santiago island is one of the largest known in the geological record. Boulders and other debris were ripped from the shoreline and hurled upward hundreds of feet. The wave itself is believed to have been some 800 feet high--enough to submerge the Statue of Liberty, or reach the second-level observation deck of the Eiffel Tower. (Ricardo Ramalho

When the massive tsunamis struck South and South-East Asia in 2004, they were about as high as 100 feet (30 meters) – huge, causing massive destruction and killing thousands. But some 73,000 years ago, the same coast suffered a much harsher fate, as they were struck by a tsunami almost 10 times bigger. Imagine this scenario: a giant volcano on

Pluto’s Charon reveals colorful and violent past

Charon in Enhanced Color NASA's New Horizons captured this high-resolution enhanced color view of Charon just before closest approach on July 14, 2015. The image combines blue, red and infrared images taken by the spacecraft’s Ralph/Multispectral Visual Imaging Camera (MVIC); the colors are processed to best highlight the variation of surface properties across Charon. Charon’s color palette is not as diverse as Pluto’s; most striking is the reddish north (top) polar region, informally named Mordor Macula. Charon is 754 miles (1,214 kilometers) across; this image resolves details as small as 1.8 miles (2.9 kilometers).

NASA’s New Horizons shuttle wasn’t only taking mind blowing photos of Pluto, it was also peeking at Pluto’s moons, especially Charon – the largest one. The latest set of images analyzed by NASA researchers revealed quite a busy past, filled with violence and geologic activity.

Paleontologists believe they have found the oldest evidence of the bubonic plague, embedded in a flea trapped in amber for the past 20 million years. This could provide insight onto how this devastating disease appeared and evolved.


Everything about the volcanoes in Italy

Mount Vesuvius erupted in AD 79 and the last eruption of this stratovolcano near Naples, Italy occurred in March 1944.

Italy is the only country with an active volcanism from Europe, with massive volcanoes that are still erupting today. Here, we’ll be looking at why the volcanoes exist in Italy, how they formed and what makes them important. Volcanism in Italy The country’s volcanism is owed to the boundary between  the Eurasian Plate and the African Plate. Most volcanoes in the

Specialists from the University of Cambridge and the University of Colorado estimate that the effects of climate change are going to take a hefty toll on our economy — $326 trillion in damage by the year 2200, roughly $201 million each hour, the Christian Science Monitor reports.

365 million year old trilobites show first signs of molting


Trilobites were some of the most dominant creatures on the face of the planet, thriving from the mid Cambrian 521 million years ago to the start of the Mesozoic, 250 million years ago. Paleontologists have now found the earliest evidence for molting – a trilobite shedding its skin 365 million years ago.

About 260 million years ago, this pre-reptile might not have looked like much. With its knobby face and about as big as a cow, Bunostegos akokanensis was actually pretty remarkable. According to a new analysis, it was actually the first creature to walk upright on all four legs, maintaining a fully erect gate.

A massive 8.3 magnitude Earthquake struck the northern coast of Chile on Wednesday night, killing at least five people and causing buildings to sway in the capital city of Santiago. Following the earthquake, waves of up to 4.5 meters were reported in some areas of the coast. About one million people were evacuated.
