Chile communications still working for many

Communications systems in Chile, a much more technologically advanced country than Haiti, are strained but still functioning for many  in the wake of the earthquake.

Updated tsunami warning system in action

This chart shows the computerized model for the propagation of tsunami waves from the Chile earthquake, color-coded to indicate maximum wave amplitude.The tsunami alerts issued in the wake of Saturday’s earthquake in Chile demonstrate how much more information is available about potential seismic threats, more than five years after the catastrophic Indian Ocean quake and tsunami.

Quake similar to 2004 Indian Ocean temblor

Scientists say the major earthquake that struck off the coast of Chile was a “megathrust” — similar to the 2004 Indian Ocean temblor that spawned a catastrophic tsunami.

How tsunamis work

A major earthquake that struck Chile overnight has sent a tsunami out into the Pacific Ocean, prompting a tsunami watch along the coasts of California and parts of Alaska and a tsunami warning for Hawaii.

Big quake question: Is nature out of control?

This color-coded map shows earthquakes that have been recorded over the previous seven days. The size of the box indicates the quake's strength, and the color indicates how recently the quake occurred. Notable quakes include the cluster of red boxes in Chile, and the blue box indicating a seismic event in Japan.Chile’s magnitude-8.8 earthquake isn’t the biggest shocker that region has seen, but one seismologist says Earth seems to be more active than it was in the 1975-1995 time frame.
