7.4 quake new aftershock in Japan

I just wanted to give people in the U.S. a comparison of quakes. For example, the Northridge quake in 1994 was only a 6.7 quake and caused 20 Billion dollars in Damage. This recent aftershock in Japan was a 7.4 in comparison. This is an unbelievably big aftershock in the scheme of earthquakes worldwide.

The Northridge earthquake occurred on January 17, 1994, at 04:31 Pacific Standard Time in Reseda, a neighborhood in the city of Los Angeles, California, lasting for about 10–20 seconds.^[1] The earthquake had a "strong" moment magnitude of 6.7, but the ground acceleration was one of the highest ever instrumentally recorded in an urban area in North America,^[2] measuring 1.7 g (16.7 m/s²)^[3] At least 33 deaths were attributed to the earthquake, with some estimates ranging much higher, and there were over 8,700 injured. In addition, the earthquake caused an estimated $20 billion in damage, making it one of the costliest natural disasters in U.S. history.^{[4]
