The path of a recent tornado that tore across the state of Kentucky has been photographed from above, revealing the massive scar it left across the land. On May 16, a deadly tornado ravaged three counties in Kentucky, taking 20 lives, destroying hundreds of houses and leaving a trail of destruction in its wake just over 55 miles long and up to a mile wide. The image of the devastation was captured the Operational Land Imager-2 (OLI-2) instrument aboard NASA's Landsat 9 Earth-imaging satellite. The track of the twister was made particularly clear in the images as it passed through the Daniel Boone National Forest, where it ripped up trees in its path.

Wanmei Liang/NASA Earth Observatory/ Landsat According to NASA and the National Weather Service (NWS), the tornado was one of the strongest ever recorded in the area, peaking at a four on the Enhanced Fujita (EF) Scale. This is the second-highest ranking on the scale, with three-second gusts between 166 to 200 miles per hour. In fact, the tornado in question was estimated to have reached speeds as high as 170 miles per hour. The Kentucky tornado was part of a severe weather outbreak over several days which hit multiple states, including Alabama, Kansas, Missouri and Virginia. At least 20 people were killed in Kentucky alone, with the office of Kentucky Governor Andy Beshear reporting that 17 people died in Laurel County, one in McCracken County, one in Pulaski County and one in Russell County.

And I want to thank all our heroic first responders for the work they've done over the past few days," Beshear said in a statement. "This is another incredibly tough time for Kentucky. And it's another reminder that life is short and it's our duty to be kind and do good. As always—we will get through this together." A 2024 study on the National Land Cover Database (which is based on Landsat observations) has found that tornado damage to forests in the southeastern U.S. is on the rise, despite a slight decrease in tornado activity across the states as a whole.

On April 22, 2025, a fire began in a wildlife management area near the town of Waretown in New Jersey. Within two days, the blaze had spread into one of the largest fires the state has seen in decades. Images captured by NASA's Landsat 9 satellite have help reveal the scope of the devastation left behind. The Operational Land Imager-2 (OLI-2) instrument on the Landsat 9 satellite sent back these images of the Jones Road fire on April 23, 2025. In this natural-color scene, thick smoke obscures the fire's mark on the land below. The burned area is revealed when viewed in shortwave infrared, near infrared and visible light. In the false-color image of the same area, unburned vegetated areas (green) and the recently burned landscape (brown) are more easily identified. The Pine Barrens, also known as the Pinelands, is located in southeastern New Jersey. It's a sprawling ecosystem covering about 1.1 million to 1.4 million acres (445,000 to 567,000 hectares). The fire has led to evacuations of people from Lacey and Ocean townships and sent smoke wafting toward New York City. Conditions have resulted in the closure of the Garden State Parkway at times. NASA is generally associated with looking outward into space, but by pointing its satellites back at our planet, the agency has been able to help reveal warning signs for large wildfires like this one in New Jersey. Earlier observations from NASA's GRACE (Gravity Recovery and Climate Experiment) and GRACE-FO (GRACE Follow On) satellites showed anomalously dry conditions in the area, pointing to the Pine Barrens being particularly susceptible to a fire in the spring of 2025. At the time of the fire, the U.S. Drought Monitor had classified drought in the region as "severe."

NASA Images Reveal Extent of Major New Jersey Fire
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. NASA has released striking satellite images that capture the devastating scale of the damage caused by the Jones Road fire, one of the largest wildfires to hit the state of New Jersey in the last two decades. The images, taken by the Operational Land Imager-2 on Landsat 9, show thick clouds of smoke and burnt landscapes across the Pine Barrens, a coastal forest known for being prone to wildfires. The fire, which started in the Greenwood Wildlife Management Area near Waretown on April 22, rapidly escalated into an emergency, affecting air quality as far as New York City. At the time, officials closed off some major roads, including the Garden State Parkway and Route 532 and ordered the evacuation of over 5,000 people in the area. They also cut power for over 25,000 as a precaution. As of April 24, more than 15,000 acres of land had been burned. Drag slider compare photos Wildland fires have long been integral to New Jersey's Pinelands, says the Pinelands Preservation Alliance, helping to rejuvenate its ecosystem by adding nutrients to the soil and creating a habitat that is essential for many species. However, combined with the recent drought and critically low levels of soil moisture and groundwater in the federally protected reserve, the fire quickly spiraled. Using NASA observations from the GRACE (Gravity Recovery and Climate Experiment) and GRACE-FO (GRACE Follow On) satellites, the National Drought Mitigation Center detected anomalously dry conditions in the Pinelands, classifying the drought in the region as "severe." Abnormally warm temperatures across New Jersey contributed to the drought, exacerbating the wildfire threat. Thankfully, rain is forecast for Friday and into Saturday, which could assist firefighting efforts. In the meantime, residents have been advised to monitor real-time updates from the New Jersey Forest Fire Service in case any new evacuation orders are put into place. Those with respiratory conditions have also been advised to stay indoors due to the current air pollution levels. An air quality official for the New Jersey Department of Environmental Protection previously told Newsweek in a statement: "Due to this being an active fire, we are monitoring the conditions and will update if necessary. The next chance of rain is this weekend, which may help improve air quality." No injuries have been reported so far, although at least one commercial building and several other smaller structures were lost in the fire. As of Thursday, about 50 percent of the fire was contained, and all evacuation orders were lifted. Authorities have arrested 19-year-old Joseph Kling of Waretown in connection with starting the Jones Road wildfire. He is currently being held in Ocean County Jail, charged with aggravated arson and arson, pending a detention hearing. Do you have a tip on a science story that Newsweek should be covering?
