tsunami scare

Sweden shook by Indonesian earthquake

The ground in Sweden shook on Wednesday, causing it to move by 1.7 centimetres, as a result of the earthquake that occurred off the coast of Indonesia.

Uppsala University's measuring stations recorded the first movement 12.5 minutes after the earthquake occurred. The earthquake peaked in Sweden 41 minutes after it was first recorded in the Indian Ocean.

"We have not seen anything like it since the earth quake and tsunami in Japan last year, when we measured a quake of about two centimetres in size," Uppsala University's seismologist Björn Lind told Swedish Radio News.

Uppsala University records around one to two earth quakes per day in Sweden. Various measuring stations, spread throughout the country, record nearly all earth quakes in the world with a magnitude of five or higher on the richter scale.

"The shift of 1.7 centimeters can be compared to the yearly rise of the ground of five milimetres in Uppsala. A quake spreading in the ground may also cause unexpected volcanic eruptions, which happened after the earth quake in Japan last year," said Björn Lind.

Despite an initial tsunami alert, the earthquake off the Indonesian island Sumatra caused no major waves to hit the surrounding shores.

According to the BBC, the relatively small waves, which measured no more than a few tens of centimetres, were due to a horizontal rather than vertical movement of the rocks where the earthquake took place.
