In other areas where creep is NOT constant, strain can build up for hundreds of years, producing great earthquakes when it finally releases. Parts of the San Andreas Fault system adapt to this movement by constant 'creep' resulting in many tiny shocks and a few moderate earth tremors. The Pacific Plate grinds northwestward past the North American Plate at a rate of about two inches per year. Many other smaller faults like the Hayward (Northern California) and the San Jacinto (Southern California) branch from and join the San Andreas Fault Zone. The San Andreas Fault is more than 650 miles long and extends to depths of at least 10 miles. The primary boundary between these two plates is the San Andreas Fault. earthquake graphics wave cross section tsunami infographic waves diagram earthquake tsunami volcanica vector isometric wave measure earthquake earthquake richter tsunami infographics. The North American Plate comprises most the North American Continent and parts of the Atlantic Ocean floor. 842 tsunami diagram stock photos, vectors, and illustrations are available royalty-free. The most destructive are the flat tectonic earthquakes. The depth of the Hipocentra is divided into shoals (up to 100 km), intermediate (from 100 to 300 km) and deep earthquakes (from 300 to 700 km). The Pacific Plate consists of most of the Pacific Ocean floor and the California Coast line. The earthquakes are divided by their origin into tectonic and volcanic. In California there are two plates - the Pacific Plate and the North American Plate. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.

Plus making any model out of Lego is always fun. This earthquake model idea helps demostrate how the underlying tectontic plates can move whilst the upper soil layer, being more elastic, gets contorted during an earthquake movement. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. Earthquake model made from lego and playdough. An earthquake is caused by a sudden slip on a fault.
