Geneva: The Swiss Seismological Service (SED) at ETH Zurich indicated on Tuesday that though moderate earthquakes occur on a regular basis in the country, “a strong or even catastrophic earthquake could also occur at anytime, anywhere in Switzerland” .The fruit of 10 years of research, SED’s updated seismic hazard model, which replaces its outdated 2004 predecessor, will enhance the organisation’s predictor capabilities as well as its ability to assess hazard levels across the confederation, where some 500 earthquakes are recorded each year, Xinhua reported.

According to improved predictive models, new and more accurate data, and reviewed estimates based on historical sources, canton Valais remains the area with the highest hazard level in the country, followed by Basel, Graubunden, the St. Gallen Rhine Valley, and central Switzerland.

SED explained that theoretically however, a strong earthquake could occur in any of Switzerland’s twenty-six cantons and at any given time. The most recent moderate earthquake to hit Switzerland dates back to three years ago, when a tremor with a magnitude of 4.2 on the Richter scale struck at 30 km below the earth’s surface in the vicinity of Zug.

A 6.7-magnitude earthquake has shaken cities on Chile’s northern coast. No damages have been reported so far, but Chile’s National Emergency Office ordered a preventative evacuation of a stretch of coast near the city of Coquimbo.

Chilean authorities said the quake didn’t have the characteristics that would generate a tsunami. The U.S. Tsunami Warning System also ruled out a tsunami.

The U.S. Geological Survey said the epicenter of the magnitude-6.7 quake was 15.6 kilometers (9.7 miles) south-southwest of Coquimbo, and had a depth of 53 kilometers. It struck at 7:32 p.m. local time.

A witness told Reuters there was minor damage to older buildings and power outages in the nearby coastal city of La Serena, a popular beach town about 400 kilometers (250 miles) north of Santiago.

“It felt very strong … the tourists were very nervous, but nothing serious happened,” Camila Castillo, a receptionist at a hotel in La Serena, told Reuters.

Chilean miner Antofagasta Plc said operations were normal at its Los Pelambres copper mine following the nearby earthquake.
