The scale was logarithmic (see above), meaning that each increasing number would be about 32 times greater, in terms of energy released, than the previous one. Surfaces waves, on the other hand, can only travel on the surface. The Richter scale was the first accurate way to give a magnitude to an earthquake, but it too had it's draw backs.

The plate that subducts is always an oceanic plate because it's more dense due to basalt being more dense than granite. It also took into account the type of movement of the fault plane. The Newport-Inglewood Fault, for example, was one of them.http://www.scienceinschool.org/2012/issue23/earthquakes,https://www.tes.com/lessons/ZuyWtedW6iv9Mw/types-of-plate-boundaries,https://www.esgsolutions.com/technical-resources/microseismic-knowledgebase/what-is-moment-magnitude,http://www.bgs.ac.uk/discoveringGeology/hazards/earthquakes/MeasuringQuakes.html,https://web.archive.org/web/20060211010253/https://earthquake.usgs.gov/regional/states/events/1933_03_11.php,https://www.sciencenews.org/article/seismologists-surprised-deep-california-quakes.Copyright
We know the velocities of the P and S wave are fixed, so if we know the time difference between them we can calculate a distance. What may be odd is that the coordinates for this cache are in Newport Beach, not Long Beach.
Lighter objects will float like an ice cube. The P-waves come first, followed by a small break before the S-waves arrive. These happen almost always in oceanic plates because they are much thiner than continental plates, more easily to tear apart. This note will not be visible to the public when your geocache is published.Hidden Likewise, if the land moves to your right, it's a right-lateral strike-strip fault. An example would be stretching a slinky and pushing it back to gather. The first type of modern measuring of earthquakes was developed by Giuseppe Mercalli, an Italian volcanologist, in the late 1800s. It's located in California, United States. Moberly Monitor Index Missouri 1933-03-11-----The final death toll was 115 people. Oceanic plates are mostly made up of basalt due to the divergent plate boundary creating new land. So only a relative number based off of interviews and surveys wouldn't be accurate, hence why there is a disagreement with large earthquakes before the Richter Scale, the next magnitude measurement scale I'll talk about. Seismographs help geologist determine the intensity as well as the epicenter and focus of an earthquake.Seismographs work by creating electricity. MARCH 10th – To American history buffs, this is the date in 1681 when William Penn was given the colony of Pennsylvania by King Charles II of England – but to Californians, an d especially to those who live in the greater Long Beach area of southern California, March 10th is chiseled in history as the date of the Great 1933 Long Beach Earthquake. There are three main plate boundaries called convergent, divergent, and transverse (transform). As lava pours out and hardens, new lava flows on top and so on. Fluids such as hard rock can pass energy more efficiently than softer rock. One type is called subduction, where one plate slides under another which almost always occur off the coast of a continent.
Body waves travel in the interior of the earth and bounce back to the surface and so on. Body waves are what you feel when an earthquake is occurring. In the early evening hours on March 10… Depending on different types of rocks and their densities, these raves can be refracted like a rainbow. The San Andreas Fault is a transform fault, and same with the Newport-Inglewood Fault. They are compressional waves, meaning the particles expand and contract on the horizontal axis. It was meant to measure intensity, not angry realized so for deep earthquakes it was highly inaccurate since depth wasn't a factor in determining a number. Rayleigh waves roll the land like a wave at the beach. It was intended to measure earthquakes in California, since all the rocks are nearly the same. Lets first discus the main types of plates.
An easy way to remember the difference between them is that the "L" in love waves makes a 90 degree angle in the direction of the wave.
Most faults in Southern California run parallel to this due to stress cracks forming in parallel lines and new faults are born.Now that you've had your history lesson, it's time for a geology lesson. Think of it as a head on collision in a car crash. Back in California, the tension began to tear the boundary between the Pacific Plate and the North American Plate. Location: 33° 37' N, 117° 58' W 5 km (3 miles) south of present-day Huntington Beach.
