The most active volcano on Earth has captured our fascination again. Not to mention our fear and respect: 1,700 people had to flee their homes as lava broke the surface near their community Thursday and Friday.The activity appears to be continuing into the weekend, with strong earthquakes of up to a highly unusual preliminary magnitude of 6.9, more ground cracks opening, and new vents opening within residential areas.Kilauea volcano, on the Big Island of Hawaii, has been erupting continually along its East Rift Zone since 1983. Most of the time, the lava flows south toward the ocean, threatening nobody. But occasionally it goes in a different direction.This is what happened this time. And luckily, no one was hurt, authorities say. 748

The plane behind Lion Air's crash off Indonesia was one of Boeing's newest and most advanced jets. It was just two months old and with 800 hours under its belt, so experts are baffled as to what exactly caused the 737 MAX 8 to crash.While no information has been released yet as to why the brand-new plane crashed into the sea 13 minutes after takeoff,?FlightRadar24 has published data that shows the plane behaving erratically during takeoff. When a plane would normally be ascending in the first few minutes of flight, the Lion Air jet experienced a 726-foot drop over 21 seconds.Aviation expert Philip Butterworth-Hayes told CNN that the data was unusual -- especially since takeoffs like this are typically controlled by the plane's automatic systems."This doesn't fit an automatic flight profile," Butterworth-Hayes said while studying the data. "Unless, the aircraft was trying to correct itself at the time for a number of reasons.""This shows an unusually unstable vertical flight profile," he added."Exactly at the same time as the speed increased there was an altitude dip, which meant that at that point there was quite some loss of control."The plane, which has only been in operation since August 15, was carrying 181 passengers as well as six cabin crew members and two pilots, bound for Pangkal Pinang on the Indonesian island of Bangka.Former US National Transportation Safety Board air crash investigator and CNN aviation analyst Peter Goelz told CNN the data clearly showed issues with both the speed and altitude of the plane."There is something obviously wrong in both the air speed and the altitude which would point to the flight control systems," he said. "These are fly-by-wire systems -- highly automated -- and pilots may not be able to troubleshoot failures in a timely manner." 1818

The race for the White House has reached its final week, and millions of Americans have already gone to the polls to cast a ballot in the 2020 presidential election.On Wednesday, a number of national and state polls were released. In general, Joe Biden is leading Donald Trump in national polls, but battleground polls show a tightening race. A CNN poll of likely voters released Wednesday afternoon showed Biden leading Trump 54-42 in the popular vote, which is slightly tighter than the 57-41 advantage the CNN poll had for Biden in early October.Another poll, one conducted by the Economist/YouGov, showed Biden leading by 11%. Emerson released its poll on Wednesday showing Biden with a 5% edge. But one poll, the Rasmussen poll, shows Trump actually ahead nationally by 1%. Polls by Rasmussen have generally been more favorable than other national polls.One national poll released on Tuesday, conducted by CNBC, had Biden up 51-40.State pollingNo matter the margin of the popular vote, the number that matters the most is reaching 270 Electoral College votes. And in that respect, Biden is leading in the polls, but his leads in battleground states is much more fragile than his standing in the national polls.In Wisconsin, a poll released on Wednesday by Marquette gave Biden a 48-43 edge. An ABC News/Washington Post poll of Wisconsin gave Biden a much larger lead of 17%, which is a bit of an outlier from other polls of the state.In Michigan, Biden held a 51-44 lead in the ABC News/Washington Post poll while he led Trump in the New York Times/Sienna poll 49-41 on Wednesday.In North Carolina, the race was a statistical tie with Biden’s advantage well within the margin of error in Wednesday’s Civitas/Harper poll.In Georgia, Biden leads 50-46 in the Monmouth poll.In recent days, polling in Arizona, Florida and Iowa have generally been within the margin of error. Biden has held a very narrow lead in Pennsylvania.Comparing 2020 to 2016The landscape of the race six days out is somewhat similar to the 2016 race.One key difference is Clinton’s lead in national polls was generally smaller than Biden’s lead. The final CNN poll, which was released two weeks before the election, gave Clinton a 5% edge. The final CNBC poll gave Clinton a lead of 9%. But other reputable polls, such as the CBS News Poll, were more narrow. The CBS News poll gave Clinton just a 3% edge. Clinton ended up winning the popular vote by 2%.Battleground state polls generally were off by a margin of 5%, which is normal in a presidential election. What made things abnormal was those polling errors were just enough to flip the election for Trump in a number of states.In Michigan, a Detroit Free Press poll released a week before the election showed Clinton up by 4 percent. She ended up losing by .2 percent.In Pennsylvania, polls generally gave Clinton a modest lead. Her lead in the final CNN poll was 5 percent a week before the election. She ended up losing by 1 percent.Wisconsin was another state Trump won by about .5%. He trailed Clinton in the Marquette poll by 6% in the final days before the election. Compared to 2016, his deficit in the Marquette poll is slimmer in 2016 than it is currently.On the flip side, polling in Nevada did not suggest a Clinton win. A CNN poll had Trump up 51-46 just days before the election. Clinton won the state by 2%.What is conclusive in pollingWhile predicting a winner in the presidential election might be a challenge based on polls, they can give an insight on what voters are thinking.One clear difference in the polls is based on gender. Wednesday’s CNN poll gave Biden a 61-37 lead among women, while Trump won with men 48-47. The poll also showed Biden leading among independents 58-36.While voters were more inclined to say Biden would do a better job handling the coronavirus, health care, racial inequality in the US and crime and safety, a slim majority, 51-46, said that Trump would do a better job with the economy. 3972

The Justice Department is expected to make the James Comey memos available to Congress on Thursday, according to a source with knowledge of the matter.The fired FBI director wrote the memos memorializing his conversations with President Donald Trump.It was not immediately whether the memos would be provided in redacted form, unredacted in a classified setting, or some combination.CNN reported Wednesday that House Judiciary Committee Chairman Bob Goodlatte might issue a subpoena to the Justice Department demanding the memos this week.The move would escalate a feud between the Justice Department and the three GOP chairmen -- Goodlatte, House Intelligence Chairman Devin Nunes and House Oversight Chairman Trey Gowdy -- who have been demanding access to the Comey memos and other records from the Justice Department as part of their investigation into the FBI's handling of the Clinton email inquiry in 2016.Gowdy told CNN on Wednesday that there's nothing in the memos that should prevent the Justice Department from providing them to Congress. He said the redactions are minor, and the larger issue is that Congress should be given access to the memos as part of its oversight role.The-CNN-Wire 1209

The number of people within the orbit of Vice President Mike Pence who have contracted COVID-19 in recent days has grown to five, according to CNN and The New York Times.Those five include Pence's chief of staff, Marc Short, an outside advisor, Marty Obst, and aide Zach Bauer.On Saturday, the Trump administration confirmed that Short had contracted COVID-19. In a statement released, the White House said that both Pence and the second lady both tested negative, and CNN reports that they tested negative on Sunday as well.On Saturday, the White House said that Pence would "maintain his schedule in accordance with the CDC guidelines for essential personnel."However, The New York Times reports that "several" White House officials privately believe that Pence should stay off the campaign trail due to the outbreak. CNN spoke with officials who said Pence staff members are "scared" of contracting the virus.Just hours after the White House confirmed Short's diagnosis, White House Chief of Staff Mark Meadows said on CNN that the Trump administration wasn't "going to control the pandemic" and would instead focus on treatments and vaccines.The outbreak within Pence's office is just the latest rash of COVID-19 cases that have reached the inner circle of the White House. President Donald Trump himself was hospitalized after contracting the virus earlier this month, and both first lady Melania Trump and her son, Barron, have also caught the virus. Several other top White House officials, including press secretary Kayleigh McEnany, adviser Stephen Miller and White House counselor Hope Hicks have also contracted the virus. 1641
