Fire crews report progress against massive Yosemite fire
அமெரிக்காவின் கலிபோர்னியா மாகாணத்தில் சான்பிரான்சிஸ்கோ அருகே உள்ள ஸ்தனிஸ்லாஸ் தேசிய பூங்காவில் கடந்த 17–ந்தேதி திடீரென தீ பிடித்தது. பின்னர் இது காட்டுத்தீயாக மாறி பூங்கா முழுவதும் பரவியது. அங்கு தொடர்ந்து வீசி வரும் அனல்காற்றினால் தீ மளமளவென பரவி வருகிறது. இந்த தீயை அணைக்க நாடெங்கிலும் இருந்து சுமார் 2 ஆயிரத்து 700 தீயணைப்பு வீரர்கள் தொடர்ந்து போராடி வருகிறார்கள். எனினும் தீயை கட்டுப்படுத்த முடியவில்லை. இதைத்தொடர்ந்து அப்பகுதியில் வசிக்கும் மக்கள் தங்கள் குடியிருப்புகளை காலி செய்து வருகிறார்கள். இந்த தீயினால் சுமார் 1¼ லட்சம் ஏக்கர் நிலப்பரப்பில் இருந்த காடு முற்றிலும் எரிந்து நாசமானது. மேலும் சுமார் 4 ஆயிரத்துக்கும் அதிகமான குடியிருப்புகளும் நாசமாகி உள்ளன. தொடர்ந்து எரியும் காட்டுத்தீயால் சான்பிரான்சிஸ்கோ நகரில் மின்சாரம், குடிநீர் வினியோகம் முற்றிலும் பாதிக்கப்பட்டு உள்ளது. இதற்கிடையே இந்த தீ அருகே உள்ள புகழ்பெற்ற யோஸ்மைட் தேசிய பூங்காவிலும் பரவ தொடங்கி உள்ளது. இதனால் கலிபோர்னியா கவர்னர் ஜெர்ரி பிரவுன் அவசர நிலை பிரகடனம் செய்து உள்ளார்.
Fire crews report progress against massive Yosemite fire
Fire officials say crews are gaining ground on a raging wildfire in Yosemite National Park that rained ash on the reservoir that is the main source for San Francisco’s famously pure drinking water on Monday. Glen Stratton, an operations chief on the fire suppression team, said late Monday that while the blaze continues to grow in size, containment numbers are up, as is optimism that crews are making progress. Stratton says while flames reached the edge of the Hetch Hetchy Reservoir, crews are confident they will be able to protect the infrastructure and expect no water or power disruptions from raining ash. Nearly 3,700 firefighters were battling the wildfire, which is the biggest on record in California’s Sierra Nevada. As of Monday evening, the blaze was 20 percent contained, the California Department of Forestry and Fire Protection said. “We’re not there yet, but we’re starting to get a little bit of a handle on this thing,” said Lee Bentley, fire spokesman for the U.S. Forest Service. “It’s been a real tiger. He’s been going around trying to bite its own tail, and it won’t let go but we’ll get there.” Earlier Monday, utility officials were monitoring clarity of the Hetch Hetchy Reservoir and using a massive new $4.6 billion gravity-operated pipeline system to move water quickly to reservoirs closer to the big city. The Hetch Hetchy supplies water to 2.6 million people in the San Francisco Bay area, 150 miles away. “We’re taking advantage that the water we’re receiving is still of good quality,” said Harlan Kelly Jr., general manager of the city’s Public Utilities Commission. “We’re bringing down as much water as possible and replenishing all of the local reservoirs.” At the same time, utility officials gave assurances that they have a six-month supply of water in reservoirs near the Bay area. So far the ash that has been raining onto the Hetch Hetchy has not sunk as far as the intake valves, which are about halfway down the 300-foot O’Shaughnessy Dam. Utility officials said that the ash is non-toxic but that the city will begin filtering water for customers if problems are detected. That could cost more. On Monday the fire was still several miles away from the steep granite canyon where the reservoir is nestled, but several spot fires were burning closer, and firefighters were protecting hydroelectric transmission lines and other utility facilities. “Obviously we’re paying close attention to the city’s water supply,” said Glen Stratton, an operations chief on the fire suppression team. Power generation at the reservoir was shut down last week so that firefighters would not be imperiled by live wires. San Francisco is buying replacement power from other sources to run City Hall and other municipal buildings. It has been at least 17 years since fire ravaged the northernmost stretch of Yosemite that is under siege. Park officials cleared brush and set sprinklers on two groves of giant sequoias that were seven to 10 miles away from the fire’s front lines, said park spokesman Scott Gediman. While sequoias have a chemical in their bark to help them resist fire, they can be damaged when flames move through slowly. The fire has swept through steep Sierra Nevada river canyons and stands of thick oak and pine, closing in on Tuolumne City and other mountain communities. It has confounded ground crews with its 300-foot walls of flame and the way it has jumped from treetop to treetop. Crews bulldozed two huge firebreaks to try to protect Tuolumne City, five miles from the fire’s edge. “We’ve got hundreds of firefighters staged in town to do structure protection,” Stratton said. “If the fire does come to town, we’re ready.” Meanwhile, biologists with the Forest Service are studying the effect on wildlife. Much of the area that has burned is part of the state’s winter-range deer habitat. Biologist Crispin Holland said most of the large deer herds would still be well above the fire danger. Biologists discovered stranded Western pond turtles on national forest land near the edge of Yosemite. Their marshy meadow had burned, and the surviving creatures were huddled in the middle of the expanse in what little water remained. “We’re hoping to deliver some water to those turtles,” Holland said. “We might also drag some brush in to give them cover.” Wildlife officials were also trying to monitor at least four bald eagle nests in the fire-stricken area. While it has put a stop to some backcountry hiking, the fire has not threatened the Yosemite Valley, where such sights as the Half Dome and El Capitan rock formations and Yosemite Falls draw throngs of tourists. Most of the park remained open to visitors. The U.S. Forest Service said the fire was threatening about 4,500 structures and destroyed at least 23. Rugged terrain, strong winds and bone-dry conditions have hampered firefighters’ efforts to contain the blaze, which began Aug. 17. The cause has not been determined.
