MILAN (AP) — The Mount Etna observatory says lava and ash are spewing from a new fracture on the active Sicilian volcano amid an unusually high level of seismic activity.The Etna observatory said a swarm of 130 tremors have been recorded by Monday midday, the most powerful registering a magnitude of 4.0. It reported lava flows from the volcano and said a new fracture had opened near its southeast crater.The owner of a refuge on the volcano says hikers are being brought down from higher elevations to 1,900 meters (6,230 feet) for their safety. But there are no reports of injuries, and so far the spewing ash was not causing disruptions to residents of nearby towns and cities.Etna, the largest of Italy's three active volcanoes, has been particularly active since July. 783

Math enthusiasts know all about it, and the rest of the population is probably hoping for cherry pie.But March 14 is Pi Day. While last year stretched the symbolic celebration out a little longer -- to 3.1415 -- each year presents ample opportunity for learning.To 31 decimal places, the celebrated irrational number that never ends is 3.1415926535897932384626433832795.A few more tidbits about pi and Pi Day:About piPi is the ratio of the circumference of a circle to its diameter. It's not equal to the ratio of any two whole numbers, so an approximation -- 22/7 -- is used in many calculations.Pi is essential in architecture and construction and was used frequently by early astronomers. Pi has been known for about 4,000 years, but it started to be called by the Greek letter only in the 1700s.The origin of Pi DayPi Day started 30 years ago at San Francisco's Exploratorium.Physicist Larry Shaw, who worked in the electronics group at the museum, started celebrating pi on March 14, 1988, primarily with museum staffers. The tradition has grown to embrace math enthusiasts from all walks of life.For more about pi, visit www.piday.org. 1159

Many voters have already cast their ballots, but that doesn't mean we'll know the election results right away. Experts say all of the ingredients are there for this election to be highly contested.“There are a lot of different reasons why the election may not be decided by the morning of November 4, and a lot of lawsuits may start to fly once that happens,” said Claire Finkelstein, law professor and director of the Center for Ethics and the Rule of Law at the University of Pennsylvania.With a record number of ballots coming in by mail, Finkelstein says the counting period will be lengthy.If a candidate declares victory on election night, but then more results come in, there could be calls for recounts, especially in states where the results are close. That could mean litigation over the counting procedures.Each states' elector will cast their vote on December 14. Then Congress meets on January 6 to count those votes and name the winner.If no candidate has a majority of the electoral votes, or if the counting period goes on and the election is still undecided, it is possible that the House of Representatives must decide.Finkelstein says that would be extraordinary and complicated.“It would likely be very contested as well, but one way or another by January 20, there needs to be a new president being sworn in,” said Finkelstein.The professor says this election is also entangled with the new Supreme Court justice.Like for Pennsylvania, which could now see a new decision on allowing mail-in ballots received up to three days after Election Day, the Supreme Court could also be involved in recounts, as happened in Florida in 2000. 1659

MAGALIA, Calif. (AP) — Ten years ago, as two wildfires advanced on Paradise, residents jumped into their vehicles to flee and got stuck in gridlock. That led authorities to devise a staggered evacuation plan — one that they used when fire came again last week.But Paradise's carefully laid plans quickly devolved into a panicked exodus on Nov. 8. Some survivors said that by the time they got warnings, the flames were already extremely close, and they barely escaped with their lives. Others said they received no warnings at all.Now, with at least 56 people dead and perhaps 300 unaccounted for in the nation's deadliest wildfire in a century, authorities are facing questions of whether they took the right approach.It's also a lesson for other communities across the West that could be threatened as climate change and overgrown forests contribute to longer, more destructive fire seasons.Reeny Victoria Breevaart, who lives in Magalia, a forested community of 11,000 people north of Paradise, said she couldn't receive warnings because cellphones weren't working. She also lost electrical power.Just over an hour after the first evacuation order was issued at 8 a.m., she said, neighbors came to her door to say: "You have to get out of here."Shari Bernacett, who with her husband managed a mobile home park in Paradise where they also lived, received a text ordering an evacuation. "Within minutes the flames were on top of us," she said.Bernacett packed two duffel bags while her husband and another neighbor knocked on doors, yelling for people to get out. The couple grabbed their dog and drove through 12-foot (4-meter) flames to escape.In the aftermath of the disaster, survivors said authorities need to devise a plan to reach residents who can't get a cellphone signal in the hilly terrain or don't have cellphones at all.In his defense, Butte County Sheriff Kory Honea said evacuation orders were issued through 5,227 emails, 25,643 phone calls and 5,445 texts, in addition to social media and the use of loudspeakers. As cellphone service went down, authorities went into neighborhoods with bullhorns to tell people to leave, and that saved some lives.Honea said he was too busy with the emergency and the recovery of human remains to analyze how the evacuation went. But he said it was a big, chaotic, fast-moving situation, and there weren't enough law enforcement officers to go out and warn everyone."The fact that we have thousands and thousands of people in shelters would clearly indicate that we were able to notify a significant number of people," the sheriff said.Some evacuees were staying in tents and cars at a Walmart parking lot and nearby field in Chico, though the makeshift shelter was to close down by Sunday. Volunteer Julia Urbanowicz said all the food and clothing was donated.Mike Robertson, who arrived there on Monday with his wife and two daughters, said he's grateful for the donations and the sense of community.A Sunday closure "gives us enough time to maybe figure something out," he said.On Thursday, firefighters reported progress in battling the nearly 220-square-mile (570-square-kilometer) blaze. It was 40 percent contained, fire officials said. Crews slowed the flames' advance on populated areas.California Army National Guard members, wearing white jump suits, looked for human remains in the burned rubble, among more than 450 rescue workers assigned to the task.President Donald Trump plans to travel to California on Saturday to visit victims of the wildfires burning at both ends of the state. Trump is unpopular in much of Democratic-leaning California but not in Butte County, which he carried by 4 percentage points over Hillary Clinton in the 2016 election.The Paradise fire once again underscored shortcomings in warning systems.Gov. Jerry Brown signed a bill in September requiring the development of statewide guidelines for Amber Alert-like warnings. A few Northern California communities are moving to install sirens after some wine country residents complained they didn't receive warnings to evacuate ahead of a deadly wildfire in October 2017 that destroyed 5,300 homes.In 2008, the pair of wildfires that menaced Paradise destroyed 130 homes. No one was seriously hurt, but the chaos highlighted the need for a plan.Paradise sits on a ridge between two higher hills, with only one main exit out of town. The best solution seemed to be to order evacuations in phases, so people didn't get trapped."Gridlock is always the biggest concern," said William Stewart, a forestry professor at the University of California, Berkeley.Authorities developed an evacuation plan that split the town of 27,000 into zones and called for a staggered exodus. Paradise even conducted a mock evacuation during a morning commute, turning the main thoroughfare into a one-way street out of town.Last week, when a wind-whipped fire bore down on the town, the sheriff's department attempted an orderly, phased evacuation, instead of blasting a cellphone alert over an entire area.Phil John, chairman of the Paradise Ridge Fire Safe Council, defended the evacuation plan he helped develop. John said that the wildfire this time was exceptionally fast-moving and hot, and that no plan was going to work perfectly.When the fire reached the eastern edge of Paradise, six zones were ordered to clear out about 8 a.m. But almost simultaneously, the gusting winds were carrying embers the size of dinner plates across town, and structures were catching fire throughout the city. Less than an hour later, the entire town was ordered evacuated."It didn't work perfectly," John said Thursday. "But no one could plan for a fire like that."Likewise, Stewart, the forestry professor, said the wildfire that hit Paradise disrupted the orderly evacuation plan because it "was moving too fast. All hell broke loose."He said experts continue to debate how best to issue evacuation orders and no ideal solution has been found.At the other end of the state, meanwhile, crews continued to gain ground against a blaze of more than 153 square miles (396 square kilometers) that destroyed over 500 structures in Malibu and other Southern California communities.At least three deaths were reported.___Associated Press writers Janie Har and Olga R. Rodriguez in San Francisco, Amy Taxin in Santa Ana, California and Andrew Selsky in Salem, Oregon, contributed to this report. 6404
