The earthquake had an estimated moment magnitude of 8.1. The movement was the equivalent of a 6.7 magnitude earthquake. A sufficiently large earthquake magnitude and other information triggers a tsunami warning. Epsilon Cassiopeiae has an apparent magnitude of 3.3. It has an apparent magnitude of +3.19. Listed are earthquakes with at least 7.0 magnitude. Aftershocks followed, including one of magnitude 5.9. The apparent magnitude of Deimos is 12.45. Whereas displacement is a vector quantity with both magnitude and direction. He said there was a lack of understanding of the magnitude of the disaster. This is a requirement of an immense magnitude. Astronomers now measure differences as small as one-hundredth of a magnitude. The table listings are in decreasing order of the magnitude of casualties. It can depend on the frequency, magnitude, and direction of the applied field. This increases stability by orders of magnitude.
