Strong and deep earthquakes shook certain parts of the world today, specifically in the northern regions of Chile and Argentina and in Fukushima Japan. Fortunately, no significant harm has been documented out of these quakes.

According to CBS Local, a preliminary magnitude 6.2 quake shook northern Argentina in the early hours of Wednesday.

The U.S. Geological Survey confirmed later on that the quake was a 6.2 magnitude and it was very deep, at over 100 miles below the surface.

The Argentina earthquake reportedly struck a remote mountainous region of the area close to the borders with Chile and Bolivia.

The agency noted that deep earthquakes cause less damage because the tremor can only be felt at the surface for their magnitude.

NDTV.com reports that the strong but deep earthquake grumbled at 1116 GMT in Argentina, 46 kilometers northwest of San Antonio de los Cobres.

The quake was said to have occurred at a depth of 257 kilometers at the Chilean border, Chile's National Emergency Center noted.

No reports of damage, injuries and casualties were documented following the incident, and the Chilean agency even announced that residents should not worry since no tsunami threat has been detected.

Meanwhile, on the other side of the world, two earthquakes struck Fukushima, Japan today, with epicenters identified to be near the nuclear plants damaged by the Fukushima disaster.

The Japan Meteorological Agency said in a statement that the first quake shook the ground at 9:45 p.m. JST while the second one struck 46 minutes later.

On the Richter scale, the first grumble was graded as a 5.0 and the second one was ranked as a 5.2.

Despite the occurrence of the two earthquakes, the Tokyo Electric Power Company said that no changes in radioactivity levels were detected at the monitoring post in the Fukushima nuclear reactors.

Similar to what happened in Argentina and Chile, the Japan earthquake didn't lead to any damage, injury or tsunami threat.

According to WesternJournalism.com, the Fukushima earthquake today was not sufficiently strong enough to damage the city and cause a tsunami.
