Earthquakes vs. aftershocksThe modern seismic activity the researchers studied is likely a mixture of aftershocks from the big quakes from the 1800s and background seismicity, Chen said. “Are small earthquakes in the New Madrid seismic zone aftershocks of 1811-1812 or not?” Hough said in an email. “The new study considers the question from a different angle, considering how tightly clustered earthquakes are, and concluding that some of the events are ongoing aftershocks,” Hough said. Aftershocks might still be continuing, but once the normal seismic rate for the area returns, she said, you can no longer identify them as aftershocks. “For this reason, we seismologists sometimes disagree about which earthquakes are foreshocks or aftershocks,” Ebel said, “and I think those disagreements are inherently unresolvable.”

At 1,600 meters (5,249 feet) tall, it’s nearly twice the height of Dubai’s Burj Khalifa, the tallest building in the world, according to a news release from Schmidt Ocean Institute, a nonprofit organization that advances oceanographic research. The ship is designed to map the seafloor by using a multibeam echosounder, which sends out sound waves to the ocean floor in a fan-shaped pattern, then measures the time it takes for the sound to reach the ocean floor and return. Schmidt Ocean InstituteThe seamount was discovered 84 nautical miles outside the Guatemalan Exclusive Economic Zone. Watling was not involved with the discovery but was part of a Schmidt Ocean Institute exploration in 2019. The recently discovered seamount may be taller than the world’s tallest building, but some have been found to have a height of 4,000 meters (13,123 feet) or more, Watling said.

NO ARCHIVES Acquire Licensing RightsCompanies Early Warning System GmbH FollowNEW DELHI, Oct 6 (Reuters) - Scientists and government authorities were working on an early warning system for glacial floods at a Himalayan lake in northeast India when it broke its banks this week with deadly consequences. If fully operational, the warning system could have given people more time to evacuate, scientists said. One scientist said glacial early warning systems can typically give residents a few minutes to an hour of notice. Details of the Lhonak Lake warning system have not previously been reported. "Such kind of events are so fast that even if we have some kind of early warning system ... we may only gain some minutes, maybe an hour," he said.

Pink diamonds take the Barbiecore craze to another level, but the rosy color comes at a cost. These gems are among the most rare and valuable diamonds around. While all diamonds form under pressure, even more force turns once clear diamonds colorful. A slight extra squeeze turns a diamond pink, and a hard squash turns it brown. But out of every thousand gems, a couple would pop up in the rarer and more valuable pink.

The World Weather Attribution initiative – a team of scientists that analyze the role of climate change in the aftermath of extreme weather events – found planet-warming pollution made the deadly rainfall in Libya up to 50 times more likely to occur and 50% worse. They also found the extreme rainfall that hit Greece, Turkey and Bulgaria was made up to 10 times more likely. Extreme rainfall has swept across large parts of the Mediterranean region since the start of the month. They found in Libya, not only did climate change make the extreme rainfall up to 50 times more likely, it also made it up to 50% more intense. The kind of extreme rainfall this region experienced is likely to happen around once every 10 years, according to the report.

Across the world, mountains with permafrost melt have shown larger and more frequent landslides, the Intergovernmental Panel on Climate Change reported. Sean Gallup / Staff / Getty ImagesBut warming temperatures due to climate change affect more than permafrost. "As mountains get smaller, they reduce pressure on the surrounding slopes, and this is often the trigger for mass movements," Knight said. Climate change puts their lives in danger from mudslides, landslides, rockfalls, and more. The futureAs climate change accelerates, mountain environments change more quickly, as well.

June 20 (Reuters) - A submersible vessel taking tourists on a deep ocean journey to view the wreckage of the Titanic has been missing since Sunday. INHOSPITABLE TERRAINIf the craft is on the ocean floor, it would be nearly impossible to rescue, experts say. The Titanic wreck is 2.5 miles below the surface. If the submersible is on the ocean floor, experts say that a sub-to-sub rescue is unlikely. Only a handful of submersible craft exist that could reach the depths of the Titanic wreck.

[1/2] A damaged vehicle is seen on top the rubbles after an earthquake in Iskenderun, Turkey February 6, 2023. The epicentre was about 26 km east of the Turkish city of Nurdagi at a depth of about 18 km on the East Anatolian Fault. During the 20th century, the East Anatolian Fault yielded little major seismic activity. But in 1822, a 7.0 quake hit the region, killing an estimated 20,000 people. The East Anatolian Fault is a strike-slip fault.

Power giant Orsted aims to build a huge offshore windfarm to help the country meet renewable goals. Last year the North Sea Transition Authority (NSTA), which regulates offshore energy activity, concluded that large crossovers between such ventures were unfeasible with current technology. This largely unreported clash risks undermining Britain's drive to meet its climate goals, according to the companies involved and a North Sea green transition expert. The BP-Orsted showdown could also presage similar disputes elsewhere in an increasingly crowded North Sea, the experts told Reuters. There is hope on the horizon for wind and CCS projects that share ground, say regulators and industry experts.

☆ I'm a scientist and a model. My days include tagging alligators, hunting pythons, and posing at luxury events in heels and full makeup.

When people who know her as a model discover she's a scientist, they respect her more, she said. We always had four wheelers and creeks and stuff like that, so I think that's definitely why I'm outdoorsy. I also do other things on the side, including python hunting, shark diving, and tagging of various species like alligators. Now I have contracts with some clothing and drink companies, and I'm also signed with an agency that does luxury event modeling. As a model, when you're talking to somebody and they find out you're a scientist it's almost like the respect for you changes.

☆ Mauna Loa eruption disrupts critical climate equipment used to measure carbon dioxide levels in the atmosphere
▼ + stars: | 2022-11-29 | by ( Rachel Ramirez | ) edition.cnn.com time to read: +3 min

CNN —The longest-running climate equipment used to measure carbon dioxide levels in the Earth’s atmosphere lost power Monday evening and is currently not recording data because of Mauna Loa’s volcanic eruption in Hawaii. Mauna Loa, the world’s largest active volcano, erupted early Monday morning for the first time in 38 years, sending lava flows cascading down slope, impacting the road used to access the Mauna Loa Observatory. The Keeling Curve graph comprises daily carbon dioxide concentration measurements taken at Mauna Loa since 1958. The fact that the tool has measured the changes of carbon dioxide levels for more than 60 years virtually uninterrupted has made it the authority source on the key greenhouse gas. The National Oceanic and Atmospheric Administration also measures carbon dioxide at Mauna Loa using a different instrument.

Scientists in Florida cut open a Burmese python to find a largely intact alligator inside. She shared a video in which the alligator was pulled out of the 18-foot-long python's digestive tract. A post shared by Rosie Moore (@rosiekmoore)The python was found and killed by employees at Everglades National Park. Last month, a missing 54-year-old woman in Indonesia had been swallowed whole by a python, according to police. A scientist in Indonesia said the woman was likely swallowed by a reticulated python, which can grow up to well over 20 feet long.
