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

WASHINGTON (KGTV) -- President Donald Trump will visit California Monday as the state continues to see widespread and deadly wildfires, Deputy Press Secretary Judd Deere tweeted Saturday.According to KABC, Trump will travel to McCleelan Park in Sacramento County. The President will be briefed on the fires, the station reports.The news of Trump’s visit comes after he signed a disaster declaration to provide federal assistance to communities affected by the fires.“THANK YOU to the 28,000+ Firefighters and other First Responders who are battling wildfires across California, Oregon, and Washington. I have approved 37 Stafford Act Declarations, including Fire Management Grants to support their brave work. We are with them all the way,” the President tweeted Friday.Trump visited California in 2018, touring the destruction left behind by the Camp Fire. 866

WASHINGTON — President Donald Trump is going to keep people in suspense about how he'll respond to the election. The Republican president is refusing to publicly commit to accepting the results in November. Trump made a similar threat weeks before the 2016 vote. Trump told Chris Wallace on Fox News Channel this weekend it's too early to make such an ironclad guarantee and scoffed at polls showing him lagging behind Democrat Joe Biden. The Biden campaign says the American people will decide the election and the government “is perfectly capable of escorting trespassers out of the White House.” Trump also is hammering the Pentagon brass for favoring renaming bases that honor Confederate military leaders.During the interview with Wallace, the president also reiterated there will not be a nationwide mask mandate. He said he is "a believer in masks," but the decision to require face coverings is up to the states to decide. 939

Pictures Group, in the statement.Although Warner Bros. did not share how many viewers watched on HBO Max, they did say that nearly half of the platform's subscribers viewed the movie on its first day on the streaming platform.Internationally, the movie grossed million. 1066

WASHINGTON (AP) — For much of the United States, invasive grass species are making wildfires more frequent, especially in fire-prone California, a new study finds.Twelve non-native species act as "little arsonist grasses," said study co-author Bethany Bradley, a University of Massachusetts professor of environmental conservation.Wherever the common Mediterranean grass invades, including California's southern desert, fires flare up three times more often. And cheatgrass , which covers about one-third of the Intermountain West, is a big-time fire promoter, Bradley said."I would not be surprised at all if invasive grasses are playing a role in the current fires but I don't think we can attribute to them directly," Bradley said.University of Utah fire expert Phil Dennison, who wasn't part of the study but says it makes sense, said, "In a lot of ways, California was ground zero for invasive grasses. Much of California's native perennial grassland was replaced by Mediterranean annual grasses over a century ago. This study doesn't look at invasive grasses in the areas that are burning in California, but invasive grasses are contributing to the fires there."Experts say the areas burning now in California are more shrubs and grasses than forests, despite what President Donald Trump tweeted over the weekend."This is a global problem," said University of Alberta fire expert Mike Flannigan, who wasn't part of the study but said it makes sense. "I think with climate change and human assistance we are moving to a grass world. One region they should have mentioned is Hawaii where wildfires are increasing in large part due to invasive grasses."Invasive species are spreading more because of climate change as warmer weather moves into new areas, said study lead author Emily Fusco, also of the University of Massachusetts. New England and the Mid-Atlantic are seeing new invasive and more flammable grasses, Bradley said.The study in Monday's journal Proceedings of the National Academy of Sciences looks at the connections between a dozen species of invasive grasses and fires nationwide, finding fires occur more often in places with the non-native grasses. But the study did not find a link between invasive grasses and the size of the fires.Four of these species, including cheatgrass and common Mediterranean grass, are in California. These grasses get dry and then watch out, Fusco said."When you start a fire normally you want kindling," Fusco said. "The grasses are, more or less, like kindling"If someone lights a match and throws in the middle of a forest, it is unlikely a fire will start, but throw it in a field of cheatgrass "and odds are that it's going to catch," Bradley said."We are the reason that invasive species are here. We are the reason that they get spread around," Bradley said.Flanagan noted that invasive plants that are not grasses also feed the wildfire problem.While most outside experts said the study was important, wildfire expert LeRoy Westerling at the University of California, Merced said that with wildfires the size is key so this study is less valuable because it measures frequency.While size matters in forest fires, study author Bradley said mid to small size fires are the ones "in everybody's backyard" and affect people and their buildings more. 3313
