A University of Utah seismologist analyzed seismic waves that bombarded Earth’s core, and believes he got a look at the earliest roots of Earth’s most cataclysmic kind of volcanic eruption. But don’t worry. He says it won’t happen for perhaps 200 million years.
“What we may be detecting is the start of one of these large eruptive events that – if it ever happens – could cause very massive destruction on Earth,” says seismologist Michael Thorne, the study’s principal author and an assistant professor of geology and geophysics at the University of Utah.
But disaster is “not imminent,” he adds, “This is the type of mechanism that may generate massive plume eruptions, but on the timescale of 100 million to 200 million years from now. So don’t cancel your cruises.” This map shows Earth’s surface superimposed on a depiction of what a new University of Utah study indicates is happening 1,800 miles deep at the boundary between Earth’s warm, rocky mantle and its liquid outer core. Using seismic waves the probe Earth’s deep interior, seismologist Michael Thorne found evidence that two continent-sized piles of rock are colliding as they move atop the core. The merger process isn’t yet complete, so there is a depression or hole between the merging piles. But in that hole, a Florida-sized blob of partly molten rock – called a “mega ultra low velocity zone” – is forming from the collision of smaller blobs on the edges of the continent-sized piles. Thorne believe this process is the beginning stage of massive volcanic eruptions that won’t occur for another 100 million to 2100 million years.

The U.S. Geological Survey reported a 3.0 magnitude earthquake struck near Irving Wednesday night.
The quake hit at 10:16 pm., with the epicenter in Irving just south of the intersection of the Bush Turnpike and Highway 114 and 3.5 miles east of Dallas/Fort Worth International Airport.
The USGS said it measured the quake at a depth of 10 miles.
In the minutes following the tremor, WFAA’s Facebook page received more than 250 comments — most of which were from people who said they felt the earth unexpectedly shaking.
“I’m in Irving off 161 and Rochelle,” wrote John Hendry. “Felt a boom and house shook; no apparent damage.”
“It freaked me out!” wrote Tonya Taylor Paris from Euless near D/FW International Airport. “My whole house rattled and crackled after it happened. My front large window rattled really loud.”
“We all thought our chairs were moving due to a plane,” said Lisa Olivero Riccetti, who was at D/FW.
“It felt like a bus ran into the building,” wrote Martin Ross at Belt Line Road and Walnut Hill Lane in Irving.
“This is the third time this has happened since I lived in these apartments,” said Veronica Rodroguez-Harris in Irving.
Last September, multiple earthquakes measuring 3.4 and 3.1 magnitude shook the same general area

The U.S. Geological Survey (USGS) said that a strong 7.5-magnitude earthquake struck off the southeastern coast of Alaska just before midnight local time last night (January 4-5, 2013). A local tsunami warning was issued for parts of southern Alaska and coastal Canada, and it has now been withdrawn. The warning area extened for about 475 miles and included coastal areas from about 75 miles southeast of Cordova, Alaska, to the north tip of Vancouver Island, Canada, the Alaska Tsunami Warning Center said. There were no initial reports of damage from the earthquake.
Here are the details of the quake from USGS:

The Bible gives many examples of signs that should warn us of the coming end of the age. Six such signs are given by Jesus, two characteristics are given by Paul, and eleven other occurrences are given by the prophets to occur prior to or soon after the end of the age. While we are also told we will not know the time of the End, God obviously wanted us to know when that time was getting closer. As the Christian church is increasingly drawn into the interfaith movement, and as more and more churches go into isolation, preparing to sleep through the growing attacks on their faith, perhaps God knew it would take a few signs to wake us up and remind us that we have work to do.
Unfortunately, many Christians take the verses that tell us we won’t know the time of His coming to mean they should ignore any and all scripture that might warn us of this time of tribulation. Others have fallen into the trap of fearing being labeled a “conspiracy theorist” should they display an interest in the Biblical prophecies about our future on Earth. My philosophy is simple. God included it Read more…
BEIJING — A series of earthquakes collapsed houses and triggered landslides in a remote mountainous part of southwestern China on Friday, killing at least 50 people with the toll expected to rise. Damage was preventing rescuers from reaching some outlying areas, and communications were disrupted.
The quakes started with a 5.6-magnitude shock before 11:30 a.m. along the borders of Guizhou and Yunnan provinces, and another equally big quake struck shortly after noon followed by more than 60 aftershocks, Chinese and U.S. government seismologists said. Though of moderate strength, the quakes were shallow, which often causes more damage.
Hardest hit was Yiliang County, where 49 of the 50 deaths occurred, said Yunnan province government agencies and state media. Another 150 people in the county were injured, said Zhang Junwei, a spokesman for the provincial seismology bureau.
China Central Television showed roads littered with rocks and boulders, and pillars of dust rising over hillcrests — signs of landslides. Footage showed a couple hundred people crowding into what looked like a school athletic field in Yiliang’s county seat, a sizeable city spread along a river in a valley bottom.
With some roads impassable, rescuers had yet to Read more…
Original Story: A powerful 7.6 magnitude earthquake struck on the west coast of Costa Rica on Wednesday, according to the United States Geological Survey. The epicenter was 38 miles south-southeast of Liberia, Costa Rica at a depth of 25 miles.
According to a statement from the Pacific Tsunami Warning Center, a tsunami warning was in effect for Costa Rica, Panama, Nicaragua, El Salvador, Honduras, Mexico, Colombia, Ecuador, Guatemala and Peru.
The tsunami watch that was issued for the entire Caribbean region was later canceled because it was inadvertently sent by mistake. No tsunami watch is in effect for the Caribbean Sea region.
A later statement said that an evaluation of the Pacific wide tsunami threat was underway and there is a possibility that Hawaii could be elevated to a watch or warning status.
Earthquakes of this size have the potential to create a widespread destructive tsunami that can affect coastlines near the epicenter within minutes and more distant coastlines within hours, but it is not known if one was generated.
According to ABC news, in the coastal town of Nosara in northwest Costa Rica, trees shook violently and light posts swayed. Teachers chased primary school students outside. There were no reports of major damage at this time.
LAS VEGAS >> About 10 minutes after a powerful, magnitude-7.4 earthquake rattled southern Mexico last month, researchers outside Las Vegas were watching a tiny tsunami churn a normally tranquil spring pool 1,700 miles away.
Three National Park Service technicians were doing maintenance on data recorders at Devil’s Hole March 20 when the waters started surging more than 2 feet high. They grabbed a camera, and their video of the rare phenomenon now has more than 47,000 views on YouTube.
