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.
Sulfur hexafluoride is a non-toxic, invisible gas that you can use to perform interesting chemistry demonstrations. Breathe it in and make your voice much deeper when you talk. It is heavier than air, so it will sink. 2  You can float light objects on the invisible gas, such as a paper airplane or a boat made from aluminum foil. 3  If you use a cup to scoop up some of the sulfur hexafluoride and dump it into a foil boat, you can sink it.
