At a glacier near the South Pole, earth scientists have found evidence of a quiet, slow-motion fault slip that triggers strong, fast-slip earthquakes many miles away, according to Cornell research published Feb. 5 in Science Advances.
During an earthquake, a fast slip happens when energy builds up underground and is released quickly along a fault. Blocks of earth rapidly slide against one another.

All that’s local is a lot more global, and scientists say solutions can only be found through broader views and collaborations nearby and far away.

Recent global calamities - the pandemic, wildfires, floods - are spurring interdisciplinary scientists to nudge aside the fashionable First Law of Geography that dictates everything is related to everything else, but near things are more related than distant things.
Geography, and by association, ecology, has largely followed what s known as Tobler s Law, which took hold in the early 1970s. But then came the novel coronavirus apparently has leapt from wildlife meat markets in China to the world in a matter of months. Global climate change creates conditions ripe for infernos in the North American west and Australia. Extreme Ohio flooding in 2018 gave way to sediments and excessive nutrients to dump into the Gulf of Mexico to the tune of some 300 square kilometers.
