A 6.4-magnitude earthquake struck Puerto Rico before dawn on Tuesday, killing one man, injuring at least eight other people and collapsing buildings in the southern part of the island. The quake was followed by a series of strong aftershocks, part of a 10-day series of temblors spawned by the grinding of tectonic plates along three faults beneath southern Puerto Rico. Seismologists say it's impossible to predict when the quakes will stop. The 6.4-magnitude quake cut power as power plants shut down to protect themselves. Authorities said two plants suffered light damage and they expected power to be restored later Tuesday. It was the second straight day in which a signifcant quake struck the island. On Monday, a 5.8 magnitude quake shook the island, causing minor damage.Puerto Rico Gov. Wanda Vazquez signed a series of executive orders Tuesday declaring a state of emergency on the island and activating the National Guard.The Associated Press reports that a 73-year-old man was killed when a wall in his home collapsed on top of him. Eight other people were injured in the city of Ponce, according to WAPA-TV in Puerto Rico.A tsunami alert was issued in the moments after the earthquake but was quickly canceled.The earthquakes on Tuesday came just a day after a 5.8-magnitude quake collapsed five homes on the south side of the island. That earthquake also caused a small landslide and some power outages, but no injuries were reported. 1461

A judge has ruled that the cases against all three defendants charged with murder in the death of Ahmaud Arbery can advance to the trial court. During a probable cause hearing Thursday, Magistrate Court Judge Wallace Harrell found that there is enough evidence for the cases against Greg and Travis McMichael and William “Roddie” Bryan to proceed.According to the Georgia Bureau of Investigation, Arbery was in the Satilla Shores neighborhood in Brunswick, Georgia, when both Gregory and Travis McMichael confronted Arbery with two firearms on February 23. During the encounter, Travis McMichael shot and killed Arbery, prosecutors said.Bryan filmed the encounter, but it took nearly 10 weeks for the video to be made public. The Georgia Bureau of Investigations said that an investigation was launched into Arbery's death as video spread online.Arbery’s death prompted a social media hashtag #JusticeForAhmaud. Arbery’s death prompted discussions nationally on the role racial bias plays in the criminal justice system. 1032

WALLOPS ISLAND, Va. – It is pretty to look at, but at times, treacherous to encounter: when snowstorms wreak havoc on the ground, it can come with a cost. Yet, because of limited research, snowstorms are not as well-understood as other weather phenomenon. That’s about to change. Inside a noisy hangar at NASA’s Wallops Island facility in Virginia sits a specially outfitted P-3 aircraft, also known as a “snow chaser.” “Snow can have a huge economic impact,” said Lynn McMurdie, principal investigator for a new research project called IMPACTS. “To be able to fly inside the clouds, where the snowflakes form, enables us to study the processes that go into forming the snowflakes that eventually fall down to the earth as snowfall in your backyard.” It’s all part of a five-year, million research project called IMPACTS, which stands for Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms. The team is embarking on its first snowstorm chasing flights this month. “It gets a bit turbulent. The plane is very capable and has great de-icing systems,” said Gerrit Everson, chief of flight operations at Wallops Flight Facility and a NASA pilot. “We would never put our crew or our passengers or the scientists in an unsafe position. So, we do a very good job at mitigating the risk. But, yeah, you do have to be willing to accept a certain degree of turbulence and bumps here and there.” It’s been 30 years since there’s been a major study of snowstorms like this one. What researchers are hoping to find out this time around isn’t just where the snow is going to fall, but how intense that snowfall might be. “People think the forecasting is really easy and simple, but it's actually very complicated,” McMurdie said. “Hopefully, we will be doing a better job so we can help joe citizen know what to do when there is a storm threatening.” Beyond that, scientists hope to also learn how snowfall can impact the water supply all over the planet. “We need water to survive and we need to understand how the water goes through the whole earth system,” McMurdie said.It’s a global ecosystem where winter wonderlands play a crucial part. 2186
