HAVANA Cheap Air Max 90 , Jan. 19 (Xinhua) -- Cuba hopes to send more than 500 athletes to the 2014 Central American and Caribbean Games, said local sports authorities.

So far, 233 athletes in 17 sports have already qualified for the 2014 Games to be held in Mexico's eastern city of Veracruz on Nov. 14 to 30, said Norge Marrero Cheap Air Max , High Performance Director of Cuba's National Institute of Sports, Physical Education and Recreation (Inder).

More athletes including several leading competitors from track and field, boxing, judo and wrestling are expected to win tickets through qualifying tournaments Cheap Nike Air Max 1 Shoes , added Marrero.

Cuba did not take part in the 2010 edition of the Central American and Caribbean Games in Mayaguez, Puerto Rico.

More than 5,300 athletes from 32 countries and regions are expected to participate in Veracruz 2014 with Cuba and Mexico the favorites to lead the medals table.

WELLINGTON， March 24 (Xinhua) -- The 7.8-magnitude quake that killed two people in New Zealand's South Island last year was so complex and unusual that it could change the way scientists think about earthquake hazards worldwide， according to a New Zealand-led study out Friday.

The Kaikoura earthquake， which shook the country in November， set records for its complexity， but was also one of the best recorded large earthquakes anywhere in the world， said the study led by scientists from the government''s Institute of Geological and Nuclear Sciences (GNS Science).

It reported on the analysis of a range of quake data including satellite radar imagery， field observations， global positioning system (GPS) data and coastal uplift data.

The authors said the quake had underlined the importance of re-evaluating how rupture scenarios were defined for seismic hazard models， which aid decision-making on things like building codes in plate boundary zones worldwide.

It showed the quake moved parts of the South Island more than 5 meters closer to the North Island in addition to being uplifted by up to 8 meters.

The earthquake ruptured at least 12 major crust faults plus another nine lesser faults.

The rupture took about two minutes to travel along more than 170 km of some well-known and some previously unknown faults.

The largest movement during the earthquake showed pieces of the Earth's crust were displaced relative to each other up by to 25 meters at a depth of about 15 km.

The maximum rupture at the surface was measured at 12 meters horizontally.

"This complex earthquake defies many conventional assumptions about the degree to which earthquake ruptures are controlled by individual faults， and provides additional motivation to rethink these issues in seismic hazard models，" the authors said.

The quake had underlined that conventional seismic hazard models were too simple and restrictive， lead author Ian Hamling， of GNS Science， said in a statement.

"The message from Kaikoura is that earthquake science should be more open to a wider range of possibilities when rupture propagation models are being developed，" said Hamling.

WASHINGTON, Feb. 11 (Xinhua) -- In her first testimony to the Congress Cheap Nike Air Max 95 Shoes , U.S. Federal Reserve Chair Janet Yellen reiterated central bank's plan to taper its stimulus exit despite recent weakness in the economy.

The current economic situation and outlook, as well as the monetary policy, were the main focus of the hearing held twice a year.

Yellen told lawmakers she expected "a great deal of continuity" in the central bank's monetary policy, saying that she served on the Fed policy-setting committee as the bank formulated its current policy strategy and she strongly supported that strategy.

Yellen Cheap Nike Air Max 90 Shoes , 67, took the oath of office to lead the Federal Reserve System on Feb. 3, succeeding Ben Bernanke, who stepped down after eight turbulent years. She was previously the Fed's vice Chair.

In the public debut in her new role Cheap Nike Air Max Shoes , Yellen said while the economy gained steam at the end of 2013, recovery in the U.S. labor market was "far from complete," underscoring the importance of considering more than just the unemployment rate when evaluating the conditions of the labor market.

Her point of keeping an eye on wider range of labor indicators is particularly important as the unemployment rate, now at 6.6 percent Cheap Air Max 1 Shoes , is near the 6.5 percent threshold the Fed once identified as the level that would need to be reached before officials would consider a hike in the interest rates.

"If coming information broadly supports the Committee's expectation of ongoing improvement in labor market conditions and inflation moving back toward its long-run objective, the Committee will likely reduce the pace of asset purchases in further measured steps at future meetings," Yellen indicated steady pullback in Fed stimulus, referring to the Federal Open Market Committee Cheap Air Max 95 Shoes , which sets monetary policy.

While admitting she was "surprised" by the two recent jobs reports that showed the pace of job creation running under what she had expected, Yellen cautioned against jumping to conclusions of the longer trend. She told the Congress that the Fed needs to see a "notable change" in the economic outlook to consider pausing its withdrawal of stimulus.

The Fed trimmed its monthly purchases of Treasury and mortgage- backed securities by a total of 10 billion dollars in both December and January, citing strengthening economy and continued improvement in the labor market.

The Fed policymakers have suggested they would continue to reduce the bond buying, which now totals 65 billion dollars a month Cheap Air Max 90 Shoes , at a similar pace at each Fed meeting and end it by the end of 2014, provided the economy develops generally in line with expectations.

Yellen also highlighted the Fed's financial regulatory role, saying that the work of making the financial system more robust " has not yet been completed."
