Fresh Burst At Indonesia's Mount Sinabung Volcano After High Alert

Mount Sinabung, a volcano in Sumatra in western Indonesia, is again spewing large clouds of gas into the air. Last week, authorities had placed the region on the highest level of alert, and are closely monitoring the volcano.

Hot ash from the volcano made its way down the slopes of the mountain and covered up to 1.5 miles, although no injuries were reported, the Associated Press (AP) reported. Indonesia’s government volcanologist Surono, who goes by only one name, urged the villagers to stay away from the main danger zone that extended up to 4 miles southeast from the crater. More than 2,700 people have been evacuated from nearby villages.

"The growing size of the lava dome is very unstable," Surono said, according to the AP, adding that boiling rocks mixed with gases may fall down from the mountain anytime. Over 50 separate eruptions were counted early Wednesday, but villages located outside the evacuated area were not in danger, the authorities said.

Mount Sinabung is a 2,460-meter tall volcano in the Karo district of North Sumatra and had also erupted in 2013, spewing a cloud of black ash and rocks nearly two miles into the sky. Authorities had then evacuated villages along the slopes of the mountain following the eruption, forcing at least 1,300 people to flee their homes.

The mountain, which is among about 130 active volcanoes in Indonesia, has been releasing smoke and ash more than 1,600 feet into the air since Monday, the AP reported. The mountain had been dormant for the past 400 years, but started erupting at irregular intervals since 2010. Last year, at least 17 people were killed after an eruption at the mountain.

The island nation is prone to volcanic activity and frequent earthquakes as it lies along the “Ring of Fire,” a nearly 25,000-mile horseshoe-shaped curve along the Pacific Ocean basin.

South Korean team wins $2M in disaster-response robot test

POMONA, Calif. (AP) — The robots drove, walked through rubble, climbed stairs, turned valves and sometimes fell, amid cheers and groans from a crowd of thousands at the Fairplex in Pomona, California.

After three years of research, development and an obstacle course of competition, a South Korean team on Saturday won the three-year and $3.5-million U.S. contest to create a robot capable of responding to disaster conditions that are unsafe for humans.

Team Kaist of Daejeon took home $2-million in first-place prize money for its DRC-Hubo robot, which successfully completed eight tasks related to disaster response in less than 45 minutes at the DARPA Robotics Challenge Finals.

The contest by the U.S. Defense Advanced Research Projects Agency (DARPA) started after the 2011 Fukushima-Daiichi nuclear disaster in Japan. Workers couldn’t vent hydrogen from the overloaded reactors without enduring excess radiation. The idea was to create a robot that could do such important emergency tasks in the future and get to the problem site.

Competition was fierce among 23 international teams, including a dozen from the United States and 11 from Japan, Germany, Italy, South Korea and Hong Kong. The robots were timed while navigating eight tasks they would likely encounter in emergency scenarios. The challenge required the teams have their robots increasingly difficult competitions over two years.

Team IHMC Robotics of Pensacola, Florida, finished second, winning $1 million for its robot Running Man. Tartan Rescue of Pittsburgh, Pennsylvania, and its robot CHIMP designed by Carnegie Mellon University’s National Robotics Engineering Center came in third, winning $500,000.

The event was live-streamed and YouTube videos culling together clips of the robots taking falls throughout the competition were tweeted out.

“These robots are big and made of lots of metal, and you might assume people seeing them would be filled with fear and anxiety,” said Gill Pratt, DARPA program manager and the competition organizer in a statement. “But we heard groans of sympathy when those robots fell. And what did people do every time a robot scored a point? They cheered! It’s an extraordinary thing, and I think this is one of the biggest lessons from DRC_the potential for robots not only to perform technical tasks for us, but to help connect people to one another.”
