VISTA, Calif. (KGTV) -- The Vista Unified School District announced Tuesday that its secondary schools would be pivoting back to virtual learning until the end of winter break.The decision only applies to district middle and high schools; students will have to finish the next three weeks of instruction virtually.Vista's elementary schools will continue with in-person learning.According to the latest community update on the district's website, the reason for the pause in in-person learning is based on the recent increase in the spread of COVID-19 "globally, nationally, regionally and locally."It goes on to say, "While Vista Unified has seen no evidence of the virus spreading within the school environment after 26 days of instruction in the Vista Classic learning model, the impact of the virus within our community is causing staffing challenges for teachers, instructional assistants, custodians, and other employees."The school board has a meeting scheduled for Dec. 15 to revisit the situation and discuss possible adjustments for the second half of the school year. 1086

WASHINGTON (AP) — Contested congressional seats in the nation's suburbs are becoming battlefields, and each party is wielding what it hopes will be a potent weapon. During the pandemic, Democrats are widely returning to the health care theme they used in 2018 to capture House control. In some races, Republicans are promoting the need for law and order after racial justice protests this summer that sometimes turned violent. Even in campaigns where the GOP has chosen a different theme, President Donald Trump's recent focus on law and order can color the debate. Each side has tested its messaging carefully and thinks the other side has chosen a losing issue. 671

WASHINGTON (AP) — Government scientists have classified 18 U.S. volcanoes as "very high threat" because of what's been happening inside them and how close they are to people.The U.S. Geological Survey has updated its volcano threat assessments for the first time since 2005. The danger list is topped by Hawaii's Kilauea , which has been erupting this year. The others in the top five are Mount St. Helens and Mount Rainier in Washington, Alaska's Redoubt Volcano and California's Mount Shasta ."This report may come as a surprise to many, but not to volcanologists," said Concord University volcano expert Janine Krippner. "The USA is one of the most active countries in the world when it comes to volcanic activity," she said, noting there have been 120 eruptions in U.S. volcanoes since 1980.RELATED: Hawaii's Kilauea could send 10-ton boulders half-mile into the airEleven of the 18 very high threat volcanoes are in Oregon, Washington and California.Government scientists use various factors to compute an overall threat score for each of the 161 young active volcanoes in the nation. The score is based on the type of volcano, how explosive it can be, how recently it has been active, how frequently it erupts, if there has been seismic activity, how many people live nearby, if evacuations have happened in the past and if eruptions disrupt air traffic.They are then sorted into five threat levels, ranging from very low to very high.RELATED: West Coast quake warning system now operational, with limitsDenison University volcanologist Erik Klemetti said the United States is "sorely deficient in monitoring" for many of the so-called Big 18."Many of the volcanoes in the Cascades of Oregon and Washington have few, if any, direct monitoring beyond one or two seismometers," Klemetti said in an email. "Once you move down into the high and moderate threat (volcanoes), it gets even dicier."The USGS said a dozen volcanoes have jumped in threat level since 2005. Twenty others dropped in threat level.RELATED: State's next big earthquake could be in SoCalThreat scores — and levels — change because of better information about the volcanoes, Klemetti said.Among those where the threat score — but not the threat level — is higher are Alaska's Redoubt, Mount Okmok, Akutan Island and Mount Spurr. Threat scores also rose for Oregon's Newberry Volcano and Wyoming's Yellowstone.None of the Big 18 changed in overall threat levels, even though 11 had overall threat scores dropping.Besides the top 5, the rest of the Big 18 are: Mount Hood, Three Sisters and Crater Lake in Oregon; Akutan Island, Makushin, Mount Spurr and Augustine in Alaska; Lassen and Long Valley in California; Mount Baker and Glacier Peak in Washington; and Mauna Loa in Hawaii. 2836

VIENNA (AP) — Eliud Kipchoge sent shockwaves through the world of sport by becoming the first athlete to break the two-hour barrier for a marathon, although it will not count as a record.The Olympic champion and world record holder from Kenya clocked 1 hour, 59 minutes and 40.2 seconds at the INEOS 1:59 Challenge on Saturday, an event set up for the attempt.Kipchoge, who compared his attempt earlier to a man landing on the moon, twice punched his chest in celebration and smiled when he finished."That was the best moment of my life," he said before adding that he trained four-and-a-half months for his extraordinary race against the clock. "The pressure was very big on my shoulders. I got a phone call from the President of Kenya."Starting at 8:15 a.m., Kipchoge was supported by 36 pacemakers who accompanied him in alternating groups, one of the reasons the IAAF governing body will not ratify the time as a world record.The groups were also helped by a pace car with a laser beam, projecting the ideal position on the road, and they received drinks handed over by cyclists and other runners to prevent them from having to slow down."It is a great feeling to make history in sport after Sir Roger Bannister," Kipchoge said in reference to the late Briton's first sub four-minute mile in 1954. "I am the happiest man in the world to be the first human to run under two hours and I can tell people that no human is limited. I expect more people all over the world to run under two hours after today."Kipchoge pointed out his mission went beyond athletics."We can make this world a beautiful world and a peaceful world," he said. "The positivity of sport. I want to make it a clean sport and an interesting sport."Kipchoge was cheered by spectators along the course in Prater Park and there were celebrations in his home country before he had even finished."Hearty congratulations, Eliud Kipchoge," President Uhuru Kenyatta said in a statement. "You've done it, you've made history and made Kenya proud. Your win today will inspire future generations to dream big and aspire to greatness. We celebrate you and wish you God's blessings."Hundreds of joyous Kenyans brought traffic to a standstill in the middle of the capital, Nairobi, as they gathered to watch the end of the run on a large screen. People pumped their fists, clapped and fell to their knees as Kipchoge cruised to the finish line.In Kenya's running mecca of Eldoret, called the home of champions, hundreds of people burst on to the streets in celebration."We should line up the entire road from the airport to Nairobi. Receive him like the hero he is," prominent activist Boniface Mwangi said on Twitter.Running at an average pace of 2:50 minutes per kilometer (4:33.5 minutes per mile), Kipchoge was 11 seconds ahead of schedule halfway through his run. He then maintained his tempo until the pacemakers left him for the final 500 meters, where he sped up."I was really calm, I was just trying to maintain the pace," said Kipchoge, adding he was never in doubt about breaking the barrier. "For me it was not 50-50, it was 90 percent."Jim Ratcliffe, founder of the chemicals company backing the attempt, exchanged high-fives with Kipchoge after the finish."He even accelerated in the final kilometer, he is a super human," Ratcliffe said. "I can't believe he's done it. He did the first half in less than an hour and then he's just done that again."Organizers said normal anti-doping regulations were in place and that Kipchoge and all the pacemakers were being tested in and out of competition by the Athletics Integrity Unit (AIU).The team behind the event "has ensured all athletes involved in the project are undergoing extensive intelligence-led testing that has been pioneered by the partnership between Abbott World Marathon Majors and the AIU," they said in a statement to The Associated Press.The Prater Park in the Austrian capital offered long straights, protected from the wind by high trees, for most of the 9.6-kilometer course, which Kipchoge completed more than 4 times.It was his second attempt at breaking the two-hour barrier, after missing out by 26 seconds at a similar event on the Formula One track in Monza, Italy, in May 2017.Kipchoge, who took Olympic gold in Rio de Janeiro in 2016 and has won 10 of his 11 marathons, holds the official world record of 2:01:39 since shattering the previous best mark by 78 seconds in Berlin last year.In near-perfect circumstances at the meticulously planned attempt, Kipchoge shaved almost two minutes off that time.Long-time coach and mentor, Patrick Sang, a former Olympic and world steeplechase silver medalist, said it was "really exciting.""I am happy for him and what he has achieved. He has inspired all of us that we can stretch our limits and that we can do more than we think we can do," Sang added.Under Sang's guidance, Kipchoge won gold in the 5,000 meters at the world championship in 2003, the start of a distinguished track career which includes Olympic bronze and silver medals from 2004 and 2008.After missing out on qualification for the 2012 London Olympics on the track, Kipchoge switched to the marathon and has since been pushing the boundaries of the discipline. 5228
