"Sound from last December's huge tsunami-causing earthquake was picked up by underwater microphones designed to listen for nuclear explosions.
Scientists this week released an audio file of the frighteningly long-lasting cracks and splits along the Sumatra-Andaman Fault in the Indian Ocean.
The spine-tingling hiss and rumble is an eerie reminder of the devastation and death that is still being tallied in the largest natural disaster in modern times.
At least 200,000 people are thought to have died as a result of the magnitude 9.3 earthquake, the tsunami, and the lack of food, drinkable water and medical supplies that followed.
The audio recording of the quake starts out silent. A low hiss begins and the intensity builds gradually to a rumbling crescendo. Then it tails off but, frighteningly, builds again in waves as Earth continues to tremble."
This gave me chills while I listened to it especially when I thought about the damage done by the tsunami that followed.
