A group of Italian earthquake experts go on trial Tuesday accused of manslaughter for allegedly not properly warning the public before an earthquake struck. The 2009 earthquake killed more than 300 people in L'Aquila Italy.

The group of earthquake experts, including scientists and government officials, are accused of giving inexact, incomplete and contradictory information to the public.

The seven scientists were members of an earthquake panel convened to assess the danger after hundreds of tremors shook the ancient, walled city.

Experts say it is impossible to predict earthquakes. Scientists around the world are watching the trial.
