New fault discovered in Bangladesh

From CNN:

Bangladesh: Hidden fault could trigger major quake
The Ganges and Brahmaputra rivers are critically important, life-giving rivers for hundreds of millions of people living in India and Bangladesh. But the millions of tons of sediment that pile up in the delta region of these rivers, a large portion of Bangladesh, could be hiding the biggest natural disaster the region has ever seen.

According to recently released research from a team of scientists led by Dr. Michael Steckler from Columbia University, buried under miles of sediment lies a locked and loaded megathrust fault that could unleash an earthquake up to 9.0 magnitude in one of the most densely populated regions of the world.

Megathrust faults occur at subduction zones, where Earth's tectonic plates are colliding with each other and one plate is moving (or "subducting") under another. These faults produce the largest earthquakes, reaching and even exceeding 9.0 magnitude, with recent examples being the 2011 Japan earthquake and tsunami, as well as the 2004 Banda Aceh earthquake and resulting Indian Ocean tsunami.

Crap - we have one of these off our coastline and the damage it could cause is well known. It would take six months for services to be fully restored if our fault produces a 9.0 quake. I cannot imagine what the loss of life would be like in Bangladesh. No building codes.
