A team of Chinese researchers used artificial intelligence to scan millions of seismic recordings and identified six never-before-documented formations deep at the boundary between Earth's mantle and its liquid outer core. The structures sit roughly 1,800 miles below the planet's surface, in one of the most extreme and least understood environments on Earth. Temperatures at […] The post Chinese scientists find six unknown structures buried 1,800 miles beneath Earth's surface appeared first on American Almanac .
A team of Chinese researchers used artificial intelligence to scan millions of seismic recordings and identified six never-before-documented formations deep at the boundary between Earth's mantle and its liquid outer core. The structures sit roughly 1,800 miles below the planet's surface, in one of the most extreme and least understood environments on Earth. Temperatures at the mantle-core boundary swing by about 1,000°C, nearly 1,800°F, across a relatively thin transition zone where solid, slow-moving rock meets liquid metal. The researchers described the formations as "deep-seated scatterers" and "thermochemical piles," terms that refer to regions where the rock composition or temperature differs sharply from the surrounding mantle…Open
A powerful magnitude 7.7 earthquake struck off the coast of Indonesia early Saturday, killing at least 20 people, collapsing buildings as well as causing panic in a region prone to deadly quakes.
AI:A powerful 7.7-magnitude earthquake struck off the coast of Indonesia early Saturday morning, resulting in at least 20 fatalities and widespread structural collapse across the region. The massive tectonic event triggered panic among local populations and caused significant damage to buildings as the tremor rolled through areas already prone to seismic activity.Open
A powerful magnitude 7.7 earthquake has struck off the coast of Indonesia, The U.S. Geological Survey says the quake hit Indonesia’s Flores region with a depth of 10 kilometers at 5:58 a.m. Saturday Indonesia time
A powerful 7.4-magnitude earthquake rips through Colombia, leaving more than 100 dead and thousands missing. According to the Associated Press, it's the largest earthquake to impact the country in a decade. #earthquake #colombia #naturaldisaster
Search teams and civilians picked through the remains of destroyed buildings in the country's third-largest city, Cali, passing large pieces of concrete and rubble down a long line of volunteers.
Time was running out to find survivors, as rescuers continued to work in the Kumamoto area on Japan 's southern main island of Kyushu, where the magnitude 7.1 earthquake hit Tuesday.
