Nicholas, intrigued by adventure stories,
Suddenly, the aftershock struck, which made the rescue work more difficult. “A nurse in the ward was covered with rubble,” a doctor screamed with horror then. We volunteers rushed to
When I looked back at the cloud, it had a small funnellooking (漏斗状的) cloud inside. We finally got to our house and then we heard a loud siren (警笛). My dad looked scared in the
About 75 percent of the city’s factories and buildings, 90 percent of its homes, and all of its hospitals were gone.
5 . Jeannette Frescas was not concerned about the Thomas Fire until the fire reached her neighborhood in Ventura, California. “At midnight, I woke up with a flashlight in my face,“ Frescas told CNN.“I looked out of my window and there were flames, a hundred feet, all around us.”
Like many residents, Frescas was caught off guard by the fire that had roared across Southern California for 13 days. She’s one of tens of thousands of residents who got into cars and fled as winds drove the third-largest fire in modern state history through Ventura and Santa Barbara counties.
“What was once a paradise (天堂) was like a war zone (地带),” Frescas said of her apartment, which was destroyed by the fire. “It’s the scariest thing I’ve been through in my entire life.” Ventura resident Patricia Rye woke up to her son-in-law pounding on her door. She didn’t get a chance to pack any valuables. “I didn’t have time to take anything,” Rye said. “My wallet, or any of my personal things.”
The fire was so terrible that more than 8,400 firefighters were working around the clock to save lives and contain (控制) it. Twelve thousand people were evacuated (撤离) in Santa Barbara County, with animals at the local zoo threatened as well. Santa Barbara Zoo closed and many animals were placed into cages in case of possible evacuations. The zoo had kept most animals indoors, away from smoke.
Meanwhile, residents who had evacuated their homes in Ventura County-where the fire began-were allowed to return on Saturday. Jim Holden considered himself lucky that firefighters saved his home and items. “They put a water screen between my house and the house next door that was burning in an attempt to save it,“ he said. “They broke in and they saved my family photos and my computer, and things that they thought would be important to me.”

8 . Established earthquake warning systems provide at best just a minute or two of notice, leaving little time for preparedness. Decades of searching for a better warning sign-changes in the geochemistry of groundwater, electromagnetic effects in the upper atmosphere, and even changes in animal behavior-have failed. Many question whether such a precursor (先兆) even exists. This situation may change soon, as recent research is providing a glimmer of hope for improved earthquake prediction.
Researchers Quentin Bletery and Jean-Mathieu Nocquet from Cote d’Azur University in France collected data from over 90 earthquakes with magnitudes larger than 7 that had occurred in the past two decades.They focused on GPS station records near these quakes, which accurately captured land movement every 5 minutes with millimeter precision. They analyzed more than 3,000 time series of motion in the 48 hours leading up to the main ruptures (断裂).
They noticed that, in the first 46 hours, the records showed no significant features. However, during the 2 hours before the earthquake, they noticed signs of increasing movement along the fault zones (断层带). Essentially, there’s a slip between plates causing the land above them to move in a measurable, horizontal direction.
Could this be just a coincidence? The probability of this increase happening just before the quake and being unrelated is extremely low, and the researchers confirmed this by analyzing 100,000 random time windows in non-earthquake GPS data. The pattern occurred only 0.03% of the time in non-earthquake data.
While this precursor signal won’t be used for warnings anytime soon, officials from the United States Geological Survey (USGS) admit that this new study provides valuable insights into how to improve their warning systems-GPS data can grease the wheels of early earthquake warnings.
The researchers admit they're still a number of steps away from putting this precursor signal into use, particularly since detecting subtle signals at individual faults requires more GPS stations. But the biggest problem is that many of the world’s earthquake regions have no instrumentation. “We can’t realize the detection at the scale of one earthquake, so we cannot make predictions,” Bletery said.
