Supervolcano fears: ‘Big One’ is coming

It should have already had several “big ones” by now. All that pressure has to go somewhere. Now geologists are nervously eyeing eight nearby volcanoes. And why has Yellowstone supervolcano been acting so weird? The U.S. Geological Survey (USGS) has warned Southern California to expect more big earthquakes to come. Some, they say, may even be more powerful than those experienced in the past few days. “(These quakes do) not make (the Big One) less likely,” local seismologist Lucy Jones told The Los Angeles Times. “There is about a one in 20 chance that this location will be having an even bigger earthquake in the next few days, that we have not yet seen the biggest earthquake of the sequence.” In part, that’s because California is way overdue for “the Big One.” The past century has been abnormally quiet in terms of large, ground-rupturing earthquakes. The last “Big One” was in 1906 when a force 7.9 earthquake realigned the real estate of San Francisco. And U.S. geologists are beginning to suspect this is not just a lucky roll of the dice. Something deep under California appears to be changing. And its implications are yet to be understood. OMINOUS SILENCE The past week’s earthquakes are the most significant experienced by Southern California since 1999. Then,…

Capuchin monkeys’ stone-tool use evolution

Preprint available here. By Bruce Bower, 11:00am, June 24, 2019: Capuchin monkeys’ stone-tool use has evolved over 3,000 years A Brazilian site shows the animals’ long history of selecting various types of pounding devices Excavations in Brazil have pounded out new insights into the handiness of ancient monkeys. South American capuchin monkeys have not only hammered and dug with carefully chosen stones for the last 3,000 years, but also have selected pounding tools of varying sizes and weights along the way. Capuchin stone implements recovered at a site in northeastern Brazil display signs of shifts during the last three millennia between a focus on dealing with either relatively small, soft foods or larger, hard-shelled edibles, researchers report. These discoveries, described online June 24 in Nature Ecology & Evolution, are the first evidence of changing patterns of stone-tool use in a nonhuman primate. “It’s likely that local vegetation changes after 3,000 years ago led to changes in capuchin stone tools”, says archaeologist Tomos Proffitt of University College London. The new findings raise the possibility that chimpanzees and macaque monkeys, which also use stones to pound…

Beluga whales from aquarium to sanctuary
