Big, destructive hurricanes are hitting the U.S. three times more frequently than they did a century ago, according to a new study.Experts generally measure a hurricane’s destruction by adding up how much damage it did to people and cities. That can overlook storms that are powerful, but that hit only sparsely populated areas. A Danish research team came up with a new measurement that looked at just the how big and strong the hurricane was, not how much money it cost. They call it Area of Total Destruction.“It’s the most damaging ones that are increasing the most,” said study lead author Aslak Grinsted, a climate scientist at the University of Copenhagen. “This is exactly what you would expect with climate models.”Looking at 247 hurricanes that hit the U.S. since 1900, the researchers found the top 10 percent of hurricanes, those with an area of total devastation of more than 467 square miles (1,209 square kilometers), are happening 3.3 times more frequently, according to a 1001

An explosion rocked a chemical plant early Wednesday in Texas, causing extensive damage across the small city of Port Neches and leaving at least three employees injured.A chemical fire continues to burn at the site, and a mandatory evacuation order has been issued within a half mile of the TPC Group plant, about 90 miles east of Houston, the Nederland Volunteer Fire Department said."There's extensive damage throughout the City," Port Neches Police Department said in a statement. "Please stay off the roads anywhere near the refineries. Obey all the barricades that are in place. We are doing everything we can to keep everyone safe and informed."Personnel have been evacuated from the plant, which makes products for chemical and petroleum companies, said TPC Group, which runs the Port Neches Operations site. About 13,000 people live in Port Neches, and some said their home windows were blown out by the blast. The fire is burning a chemical called butadiene, police said. A colorless gas, butadiene is considered a health hazard, according to the US National Library of Medicine. It is made from processing petroleum and is used to make synthetic rubber and plastics."Our focus is on protecting the safety of responders and the public, and minimizing any impact to the environment," TPC Group said.The injured employees are undergoing treatment, the company said.'Then I noticed an orange glow'Tyler Shawn Dunlap was sleeping when the explosion rocked his house."I heard and felt my house shake. I first thought people were coming to break in 'cause of our intense security," he told CNN. "I went to Dad's room, and he thought our generator blew up, so we checked that, then I noticed an orange glow from the clouds."Trent Lee said the explosion sounded like a nuke and shook everything in Port Neches. The blast was also captured on Mia Hubert's 1869
