Seismic activity in Iceland's Eyjafjallajökull volcano started at the end of 2009, and increased gradually until the end of March 2010. On April 14, 2010, the eruption started a second phase, which resulted in a volcanic ash cloud which covered Europe, with most airports and airspace closing until April 20.Thousands of passengers were stranded in airports around the world as a result of the ash cloud. In Israel, the ash passed over at 20,000 feet (6,100 meters), spreading south and east.Chilean miners' rescueThe last of the 33 Chilean miners who were trapped underground for 69 days was rescued on October 14, 2010. No one has ever been trapped so long and survived. Luis Urzua ascended smoothly through 2,000 feet of rock, completing a 22½-hour rescue operation that unfolded with remarkable speed and flawless execution, before a jubilant crowd of about 2,000 people.The rescue operation, which riveted the world, exceeded expectations every step of the way. Officials first said it might be four months before they could get the men out; it turned out to be 69 days and about 8 hours. Once the escape tunnel was finished, they estimated it would take 36 to 48 hours to get all the miners to the surface. That got faster as the operation went along, and all the men were safely above ground in 22 hours, 37 minutes.The miners have accepted an Israeli invitation to visit the Holy Land for Christmas.US Republican House victory Republicans rode a wave of voter discontent and conservative outrage to capture a House of Representatives majority from US President Barack Obama's Democrats on November 2, 2010, rolling up historic gains and ending the Democrats' reign after just four years.The Republican victory eclipsed their 54-seat pickup when they retook the House in 1994 for the first time in 40 years and the 56-seat Republican gain in 1946. Democrats had captured only 2 Republican seats.The Republican party — energized by the ultraconservative tea party movement and voter disillusionment with Obama, incumbents and high unemployment — captured 58 seats by early Wednesday from Democrats, easily exceeding the 40 needed to gain a majority.Republicans piled up their biggest House gains since they added 80 seats in 1938, during the Depression.The latest WikiLeaks releases
