Mars geologically active, planet experiencing 7.0 magnitude quakes say scientists

February 21, 2012 SPACEWith High Resolution Imaging Science Experiment (HiRISE) imagery, the research team  examined boulders along a fault system known as Cerberus Fossae, which cuts across a very young (few million years old) lava surface on Mars. By analyzing boulders that toppled from a Martian cliff, some of which left trails in the coarse-grained soils, and comparing the patterns of dislodged rocks to such patterns caused by quakes on Earth, the scientists determined the rocks fell because of seismic activity. Gerald Roberts, an earthquake geologist with Birkbeck, an institution of the University of London, who led the study, said that the images of Mars included boulders that ranged from two to 20 meters (6.5 to 65 feet) in diameter, which had fallen in avalanches from cliffs. The size and number of boulders decreased over a radius of 100 kilometers (62 miles) centered at a point along the Cerberus Fossae faults. This is consistent with the hypothesis that boulders had been mobilized by ground-shaking, and that the severity of the ground-shaking decreased away from the epicenters of mars-quakes,” Roberts said. The team compared the pattern of boulder falls, and faulting of the Martian surface, with those seen after a 2009 earthquake near L’Aquila, in central Italy. In that event, boulder falls occurred up to approximately 50 km (31 miles) from the epicenter. Because the area of displaced boulders in the marsscape stretched across an area approximately 200 km124-miles) long, the quakes were likely to have had a magnitude greater than 7, the researchers estimated. By looking at the tracks that the falling boulders had left on the dust-covered Martian surface, the team determined that the mars-quakes were relatively recent – and certainly within the last few percent of the planet’s history – because Martian winds had not yet erased the boulder tracks. Trails on Mars can quickly disappear – for instance, tracks left by NASA robotic rovers are erased within a few years by Martian winds, whereas other, sheltered tracks stick around longer. It is possible, the scientists concluded, that large-magnitude quake activity is still occurring on Mars. –Physics
For those of you following The Extinction Protocol book, see pages 479-480 on why I said, two years ago, seismic quakes and avalanches were occurring on Mars and why the same forces would accelerate their increase on Earth.

    Hi Alvin,
    I do have your book but haven’t read that far into it yet.
    Is there something disturbing our solar system to cause the other planets to react as well as our earth?

    I don’t have your book, but I’ll look for it. I did read somewhere about avalanches occurring on Mars. Also there was something about Pluto warming up, and even changing color. I found a web site that indicates unusual solar activity is the cause, and that much worse is on the way. I’m just wondering if your discoveries involve the solar activity, or something else, such as NASA’s magnetic “fluff”? Anyway, here’s the site:

    “At a certain moment, when the sun’s magnetism reaches a crucial point, the sun’s surface will be subjected to immense storms. Enormous electro-magnetic forces will then be liberated – with unknown strength – from the interior of the sun. Giant sun-flames will send a gigantic wave of particles to the earth. Recently this phenomenon has been observed and confirmed in several suns. During several hours and days they exhibited an explosive activity, after which they returned to their normal state. Astronomers were wondering if this were one-time event or if it could occur more often. They can be sure it will occur again! Our sun is also showing this kind of pattern.”
