Speaking to Reuters, Kerry Sieh - director of the Singapore Earth Observatory - said the earthquake and a strong aftershock followed the "ice skating" earthquakes - the earthquake in which the ice blocks slipped. across each other, and is the strongest earthquake of this type ever recorded.

'It (the 8.7-magnitude earthquake - NV) is really an unusual and rare event - he said - Not only is the biggest' ice-skating 'earthquake, the aftershocks caused by it are also very big, is the second biggest aftershock we've ever recorded. '

Sieh said the quake also increased the risk of a massive earthquake in a similar area to the 2004 earthquake that killed more than 230,000 people.

Mr. Sieh's information was remarkable, because he had many years of studying seismic activity, faults . around Sumatra - where many earthquakes and deadly tsunamis occurred.
