Two big earthquakes that struck off the Indonesian province of Aceh yesterday caused the deaths of five people in Aceh - three from heart attacks and two from shock.

Disaster officials have expressed relief over the low casualty figures compared to the numbers that perished during the 2004 tsunami.

Scientists meanwhile have been explaining why there was no tsunami.

They say the main difference was that in 2004, one tectonic plate slipped beneath another, displacing a huge volume of water.

Yesterday's quakes in contrast resulted from the plates rubbing laterally against each other - their movements although violent were less likely to create huge waves.

Experts say that the authorities in Indonesia and in other countries were not wrong to evacuate people - because the seismological information available at the time suggested there could have been a big tsunami.

Meanwhile, eminent professor of Geology Kapila Dahanayake explained how earthquakes that occur in the world can not be predicted.

He added that not every under-sea earthquake will generate a tsunami.

Professor Dahanayake explained further.
