Radon gas emissions warn of tectonic activity
Radon gas is emitted naturally from the earth in constant patterns. But variations result from tectonic activity between plates in the earth’s crust, movements which generally precede earthquakes. Detecting these variations can therefore warn authorities of impending earthquake or volcanic activity. But the radon measurements enable scientists to predict activity before it happens, which is good news in such a tectonically active country as Chile. Over 16 major tremors of 6 or more on the Richter scale have been recorded in Chile since 1900, with last year’s Papudo quake reaching 6.3 in magnitude. The 2007 Antofagasta earthquake reached 7.7 in force leaving two people dead and 150 injured, as well as destroying 4,000 homes (ST. Nov 15 2007). About the writer![]() James FowlerA native of the North of England, James has divided most of his life between the cities of Newcastle and Leeds. After graduating with a history degree from the University of Leeds in 2007, he spent 15 months traveling South East Asia and Australia. This trip, following on from a year studying in Canada, has reinforced the traveling spirit in side of James. Residing in Santiago under the pretense of improving his language skills, he now realizes that learning Spanish in Chile is as hard as learning English from a Geordie.
He currently gets to translate his passion for sport into writing, temporarily agreeing to sell his soul and call football 'soccer'. He is really enjoying Chile, particularly the weather and wonderfully cheap wine. |
