Will Supercomputers Create Virtual Maps of Your Body in the Future? - Read More Why Rockfalls Happen on Beautiful Days in Yosemite onianmag.com/science-nature/why-rockfalls-happen-beautiful-days-yosemite-180958581/ \"Rockfalls happen about 60 to 70 times per year in Yosemite, but usually they have an obvious cause. A winter storm has blown through, or there was an earthquake. But some, like the Happy Isles incident, happen on beautiful, clear summer days for no apparent reason. Now a pair of scientists says they know what’s behind these rockfalls—it’s the warm, sunny weather itself.\" What Is A Rockfall? \"Rockfalls are a natural and dynamic geologic process involving the detachment and rapid downward movement of rock. Historical records indicate that more than 1,000 rockfalls have occurred in the park during the past 150 years. Massive piles of \"talus\" or rock debris at the base of Yosemite Valley's cliffs are reminders of these dramatic events.\" Second Yosemite Rockfall in Two Days Injures One at El Capitan \"Ageologist had inspected the face of El Capitan in a helicopter during the afternoon and ... more scientists were working into the evening, using lidar scanning technology and computer modeling, to determine the size of the rockfall and how it broke away.\" ____________________ Science In The Extremes ventures to the ends of the earth to bring you pioneering research and innovations that are advancing our civilization and broadening our understanding of the universe.
