According to several US news agencies (c.g. CBSNEWS), the USGS provided a comparison to help people gain perspective of Japan's recent earthquake.
It was cited that
"USGS compared Japan's earthquake with two well known quakes: last year's earthquake in Haiti and the historic 1906 San Francisco quake.
The USGS calculated the magnitude 8.9 earthquake in Japan [on March 11, 2011] to be 700 times stronger than Haiti's recent magnitude 7.0 earthquake, which devastated Port-au-Prince and killed more than 300,000 people.
When comparing to the San Francisco magnitude 7.9 earthquake in 1906, the USGS has figured that Japan's earthquake is equivalent to 30 times stronger."
