On May 18, 1940, an earthquake of magnitude 7.1 occurred along a previously unrecognized fault in the Imperial Valley. Similar movement on the Imperial fault occurred during an earthquake in November 1979. The greatest surface displacement was 17 feet of right-lateral strike-slip in the 1940 earthquake.Clearly, this fault is part of the San Andreas system.he 1906 earthquake, which has been estimated at a magnitude 8.3 on the Richter Scale, caused intensities as high as XI on the Modified Mercalli Scale. Surface offsets occurred along a 250- mile length of the fault from San Juan Bautista north past Point Arena and offshore to Cape Mendocino.
Iron is a magnetic substance, which means it is attracted by a magnet. On the other hand, Sulfur is a non-magnetic substance. If you place a magnet near a mixture of Iron and â¦ Sulfur, the iron pieces will stick to the magnet, while the sulfur powder will remain.
A magnet's magnetic moment (also called magnetic dipole moment and usually denoted Î¼) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, and
