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.
