Japanese inspired double tsunami in March

The earthquake in March created two tsunamis and they overlapped, causing the level of devastation to skyrocket when the waves hit the shore.

Japan's northeast coast suffered a tsunami after a 9-magnitude earthquake on March 11 that left at least 20,000 people dead and missing. In addition, the double disaster also devastated many Japanese provinces and cities and caused a nuclear crisis at the Fukushima I. power plant.

Most scientists think tsunami on March 11 is a single tsunami. But the photos that some US and European artificial satellites sent showed that two tsunamis formed in the Pacific after successive earthquakes. They overlap and form a wave twice as high as the original two waves, AFP said.

'That huge wave is capable of spreading very far and its power has not decreased. The mounds and mountains of the ocean floor pushed two waves in the same direction from where they came from. This finding explains why tsunamis can cross continental shelves and cause widespread destruction in some areas while many others are unharmed. ' USA (NASA) announced on their website.

Tony Song, a NASA scientist, says the probability that a satellite captures a double tsunami is only one in 10 million.

'For decades, some researchers have suspected that double tsunamis caused a catastrophe in 1960, but since then we have actually seen double tsunami images , ' Song said.
