Unusual Seismic Activity in Caribbean, Says Expert
“Port-au-Prince, Nov 15 (Prensa Latina) Seven quakes have rocked Caribbean islands as of Saturday and another tremor occurred in Haiti this Monday, arising concern among experts about a likely seismic reactivation in the area.
‘For some days we have observed an unusual activity that seems to be linked to the subduction of the Caribbean tectonic plate,’ Saint Lucian seismologist Bruce Kleever told Prensa Latina.
Seven tremors were felt in the British overseas territories in East Caribbean over the weekend, according to the Disaster Management Department of the Virgin Islands.
‘The seisms were of 3.5-4.6 magnitude and could also be felt in Puerto Rico. We’re following closely the situation in the area,’ said Kleever.
A 4.3-magnitude quake rocked southern Haiti early morning today, one year, ten months and two days after the worst seism in the history of this country occurred.
No damages or fatalities have been reported so far, but the people panicked as they relived the nightmare.
According to the expert, the tremor might indicate an area of seismic activity also in the northern Caribbean plate.
For years, the specialists have feared the likelihood of powerful quakes and ensuing tsunamis in the Caribbean because of the existence in the area of important focuses of danger of tectonic movement. One of them is located near Dominica, considered the point with the largest number of potentially active volcanoes in the world.” Read more.

Oklahoma Earthquakes Stronger Than Fracking Tremors, Experts Say – “Thousands of times every day, drilling deep underground causes the earth to tremble. But don’t blame the surprise flurry of earthquakes in Oklahoma on man’s thirst for oil and gas, experts say. The weekend quakes were far stronger than the puny tremors from drilling – especially the controversial practice of hydraulic fracturing. The weekend quakes didn’t have the mark of man. They were a force of nature… The magnitude-5.6 quake that rocked Oklahoma three miles underground had the power of 3,800 tons of TNT, which is nearly 2,000 times stronger than the 1995 Oklahoma City bombing.” Read more.

“The largest earthquake ever reported in the state of Oklahoma struck Saturday night, officials said.
The temblor had a magnitude of 5.6 and its epicenter was four miles east of Sparks in Lincoln County, according to the Oklahoma Geological Survey. The quake hit at 10:53 p.m.
The quake was reportedly felt as far away as Illinois, Kansas, Arkansas and Texas.
‘There’s a crack going from the closet to the ceiling. I’ve never seen that before. I was in my bedroom grabbing my phone and I happened to notice it,’ Moore resident Todd McKinsey said.
McKinsey said he lives near NW 12 and Santa Fe Avenue.
‘That’s drywall. It’s totally separated,’ he said.
‘Earthquake damage in Oklahoma, that’s an anomaly right there,’ McKinsey said.
‘The picture by the TV fell off the wall and we jumped up because we thought somebody had hit the house,’ Noeh Morales said.
‘It was like a roaring noise. I’ve never one that bad over here,’ he said.
Morales said he was asleep at his home near SW 69 and Pennsylvania Avenue.
‘It woke me out of a dead sleep. I felt the whole house shaking. I jumped and ran outside to see what was going on,’ he said.
The strongest earthquake previously reported was April 9, 1952 in El Reno, according to the geological survey. Its magnitude was 5.50.
The Lincoln County sheriff’s office said late Saturday that damage has been reported across the county, but were still responding to calls and was not sure of the extent of damage. The Oklahoma City fire department reported no injuries or serious damage as of 11:15 p.m.” Source – NewsOK.

Study: Earthquakes Have Claimed More Than 780,000 Over Past Ten Years — 60% of All Disaster-Related Deaths
“EARTHQUAKES claimed more than 780,000 lives in the past decade, accounting for nearly 60 per cent of all disaster-related deaths, according to a study published in The Lancet today.
‘In addition to these deaths, earthquakes have directly affected another two billion people in this period,’ it added.
The deadliest quake was the January 12 2010 7.0-magnitude event in Haiti which killed 316,000 people.
This was followed by the December 26 2004 Indian Ocean tsunami, generated by a 9.1-magnitude tremor, in which 227,000 people died.
Third-ranked was the May 12 2008 7.9-magnitude quake in south-western China’s Sichuan province, which inflicted a death toll of 87,500.
The review study seeks to give emergency responders and policymakers a snapshot of the scale of earthquakes as a health priority, and to warn doctors about the kind of injuries they are likely to confront.
‘Massive earthquakes can result in casualty rates ranging from one to eight per cent of the at-risk population,’ it said.
‘The reported ratios of death-to-injury vary, but across many studies seems to be about 1-to-3.’
The death toll unfurls in waves, starting with immediate fatalities from falling buildings, which is followed several hours later as people die from catastrophic injuries to internal organs, says the investigation.
A third wave occurs in the days to weeks afterwards among people with sepsis and multiple organ failure.
Among survivors, the main injuries are crush-related damage to the kidneys, liver and spleen, followed by spinal damage, bone fractures and lacerations.” Read more.
Geologists Closely Monitoring Surge in Central Arkansas Earthquakes, Layout of Tremors Could Suggest Larger Quake Coming
By Gavin Lesnick – “LITTLE ROCK — The Arkansas Geological Survey says it is stepping up its monitoring of seismic activity in central Arkansas after dozens of small earthquakes in the region.
Six minor quakes were recorded Friday near Quitman, the latest of more than 50 temblors in October. The Friday tremors began with a 2.0-magnitude quake around 7:45 a.m. and peaked with a 2.5 quake later in the morning.
The shaking follows more than 1,000 earthquakes centered between Guy and Greenbrier from September 2010 to July of this year, when the Arkansas Oil and Gas Commission ordered four gas disposal wells shut down and voted to create a large moratorium area in which no future disposal wells could be drilled.
Geologists said the activity – which involves injecting pressurized liquid into the ground – was likely contributing to the shaking.
The quakes between Guy and Greenbrier tailed off significantly in August, but more quakes began occurring in October closer to Quitman. It sits about 10 miles northeast of Guy.
That distance is potentially concerning, warned Scott Ausbrooks, geohazards supervisor for the Arkansas Geological Survey. The Quitman quakes are occurring along the same line as the Guy-Greenbrier ones, but there’s a miles-long gap between Guy and Quitman in which no quakes have been recorded.
That might suggest that the tension is building, possibly leading up to a larger quake centered on that gap along the fault. A similar-sized gap occurred on the southern end of the Guy-Greenbrier fault and it in February unleashed a 4.7-magnitude quake, the largest of any of the recent tremors.
Anytime there is a gap in seismicity along an active fault, it ‘bears watching,’ Ausbrooks said.” Read more.
Strong 6.9 Magnitude Earthquake Rattles Peru, Knocks Out Power
Richter Magnitude 6.9 – NEAR THE COAST OF CENTRAL PERU

Depth: 23.9 km (14.9 miles)
“A magnitude 6.9 earthquake struck off the west coast of Peru, rattling residents in cities still recovering from a temblor that killed more than 500 people in 2007. No fatalities were immediately reported.
The temblor knocked out power and sent people running from their homes near its center 178 miles (286 kilometers) south- southeast of Lima. In Ica, which was devastated by the magnitude-8 quake in 2007, a cathedral wall and church tower collapsed, along with several mud brick buildings, said Juan Carlos Romani, a spokesman for the city council.
‘It was very strong but quick,’ said Romani in a telephone interview from Ica, adding that there were no reports of injuries, though power and phone service hadn’t fully returned. ‘It lasted ten seconds at most but was very violent.’
In Lima, buildings shook for about a minute, and had to be evacuated amid aftershocks, though no damage was immediately reported in the capital.” Read more.
Obama Has Declared Record-Breaking 89 Disasters So Far in 2011
By Amy Bingham – “From Hurricane Irene, which soaked the entire East Coast in August, to the Midwest tornadoes, which wrought havoc from Wisconsin to Texas, 2011 has seen more billion-dollar natural disasters than any year on record, according to the National Climatic Data Center.
And as America’s hurricanes, floods, tornadoes and wildfires set records this year, so too has President Obama in his response to them.
During the first 10 months of this year President Obama declared 89 major disasters, more than the record 81 declarations that he made in all of 2010.
And Obama has declared more disasters — 229 — in the first three years of his presidency than almost any other president signed in their full four-year terms. Only President George W. Bush declared more, having signed 238 disaster declarations in his second term, from 2005 to 2009.
But while the sheer number of bad weather events played a big role in the uptick in presidential disaster declarations, Obama’s record-setting year may have something to do with politics as well.
‘There’s no question about it that the increase in the number of disaster declarations is outstripping what we would expect to see, given what we observe in terms of weather,’ said Robert Hartwig, the president and economist at the Insurance Information Institute. ‘There’s a lot of political pressure on the president and Congress to show they are responsive to these sorts of disasters that occur.’
While the president aimed to authorize swift and sweeping aid to disaster victims, Congress was entrenched in partisan battles over how to foot the bill.” Read more.

Turkey: Seismologists Fear Eruption of Nemrut Volcano After Massive 7.2 Earthquake
“TURKISH seismologists fear that the earthquakes that hit the province of Van on Sunday can cause eruption of Nemrut volcano located northwards of Lake Van, PanArmenian reported.
Mt Nemrut is near Tatvan, a small town in the eastern Anatolian province of Bitlis. The mountain rises from the southwestern shore of Lake Van, and enters the district of Ahlat to the north.
At least 217 were killed and more than 1,000 people injured when a powerful earthquake struck Turkey, collapsing dozens of buildings and pulling down phone and power lines in the southeast of the country, officials and witnesses said. More than 1,000 people are feared killed in the earthquake.
Another magnitude 6.1 earthquake, which was the second to rock the country in the past 24 hours, was registered about 20 km from the city of Van at the depth of some 10 km.” Source.
Deadly 7.2 Magnitude Earthquake Rocks Eastern Turkey, Dozens of Buildings Collapse, Significant Casualties Reported

Richter Magnitude 7.2 – EASTERN TURKEY
Sunday, October 23, 2011 at 01:41:21 PM
38.628°N, 43.486°E
Depth: 20 km (12.4 miles)
“A powerful earthquake with a magnitude of 7.2 shook southeastern Turkey on Sunday, Turkey’s Kandilli Observatory said, triggering the collapse of buildings and killing scores of people.
Turkey’s main seismography center says the quake could have killed up to 1,000 people.
The Kandilli observatory’s estimate is based on the strength of the quake and the structure of the housing in the area.
‘We are estimating a death toll between 500 and 1,000,’ Mustafa Erdik, head of the Kandilli observatory, told a televised news conference Sunday.
Turkey’s deputy prime minister said around 45 buildings have collapsed in the town of Ercis and the city of Van. Ercis sits on a geological fault line.
‘A lot of buildings collapsed, many people killed, but we don’t know the number. We are waiting for emergency help, its very urgent,’ Zulfukar Arapoglu, the mayor of Ercis district, which was hit badly, told the news broadcaster NTV.” Read more.
Japan: 3/11 Earthquake Caused Archipelago to Move Eight Feet East and Sunk The Nation Nearly One Inch
By Julian Ryall – “The massive earthquake that struck Japan in March shifted the entire archipelago nearly 8 feet closer to the United States and caused the nation to sink close to 1 inch.
The magnitude-9 quake – the largest in recorded history in Japan – also jolted the planet on its axis by nearly 4 inches.
Experts at the Geospatial Information Authority of Japan have confirmed that the standard datum of levelling – the benchmark for measuring heights above sea level throughout Japan – sank 2.4cm (0.9 inch) as a result of the earthquake.
The change in the figure was the first since the Great Kanto Earthquake killed an estimated 105,000 people in Tokyo in 1932.
That quake had a magnitude of 8.2 and caused the ground level to sink 3.4 inches into the Pacific.
The movements were even more pronounced in parts of north-east Japan that were closest to the epicentre of the earthquake.
Experts and the GIA have calculated that the Oshika Peninsula, just to the north of the devastated town of Ishinomaki, shifted more than 17 feet to the east and sank nearly 4 feet into the Pacific Ocean. Both figures are records for land mass movements caused by a tremor in Japan, and the impact is clearly visible in the villages that dot the inlets of the peninsula.
