You might have heard about a major solar storm that is hitting Earth right now. It's the biggest to hit us since 2005. You've also probably heard a few people say, "I didn't feel anything."
As our friends at 13.7explained earlier today, the storms have the ability to disrupt sensitive electronics and even the power grid. Usually none of those things happen. But, today's solar storm did cause a bit of disruption.
With the skyline of Youngstown, Ohio, in the distance, a brine injection well owned by Northstar Disposal Services LLC is seen in Youngstown on Jan. 4. The company has halted operations at the well, which disposes of brine used in gas and oil drilling, after a series of small earthquakes hit the Youngstown area.
Small earthquakes in Ohio and Arkansas associated with hydraulic fracturing for natural gas have taken many people by surprise. Gas industry executives say there's no hard evidence that their activities are causing these quakes. But some scientists say it's certainly possible; in fact, people have been causing quakes for years.
In the 1960s, geologists realized that gold mines in South Africa had created small earthquakes. Caverns dug into the earth thousands of feet below the surface collapsed. The "pancake" effect caused quakes — in one case a magnitude-5.2 temblor.
100 years ago yesterday, Norway’s Roald Amundsen beat England’s Robert Scott in man’s race to reach The South Pole. A mission of science propelled many of these early expeditions, and such inquiry continues as the remarkable endeavor of polar scientists today.
