A significant number of FMSs are utilized with first-motion data represented on beach-ball diagrams. FMSs are tabulated using the dip azimuth and dip angle of the inferred fault plane and the rake of the hanging-wall slip vector.
What kind of diagram is a beach ball? These diagrams are called focal mechanism diagrams, or sometimes "beach-ball" diagrams. These circular diagrams shown in the following figure are able to illustrate the strike of a plane with respect to North and its dip, where the straighter the line the more vertical the dip.
I first heard of the beach ball metaphor while watching a video through PESI (one of my continuing education providers). Arielle Schwartz, Ph D (see her books here) uses the beach ball metaphor to explain how we can manage our dysregulated emotions. Arielle Schwartz, PhD provides a mind-body healing exercise that can help trauma …
This Demonstration generates earthquake focal mechanism plots, also called fault plane solution plots or simply beach balls. You can define the strike, dip, and rake angle of a fault and choose between …
Beach volleyball competitions can be held on a natural beach so long as the beach is level and the sand is at least nine inches deep and free from rocks, gravel and other hazardous objects.
ing black and white quadrants. This sphere looks like a beach ball, and sometimes a figure showing focal mechanisms is referred to as a "beach ball" diagram. The black quadrants represent areas that moved away from the earthquake's hypocen-ter, whereas the white quadrants represent areas that moved toward the earthquake's hypocenter.
FMS beachball diagrams are lower-hemisphere stereographic projections that show two black quadrants and two white quadrants separated by great- circle arcs oriented 900 from each other.
The fault orientation and the slip direction of an earthquake are described by something called a focal mechanism. And focal mechanisms are usually visualized by what are called "beachball" diagrams. These diagrams are circles with various shading that form arcs across the circle—hence the beachball nickname.
Data from these stations can also be used to derive useful information about the nature of the fault that ruptured, usually provided in the form of beach-ball like focal mechanisms, which are based on the first motions of the seismic waves generated by an earthquake, which will be different at different seismic stations depending on their ...
Free body diagram of a brick sitting on the bottom of a pool. The water displaced by an entire beach ball weighs more than a beach ball, so if you hold one under water the buoyant force will be greater than the weight. Your hand is providing the extra downward force to balance out the forces and maintain static equilibrium (left diagram).
The first screen also contains a button to show the different zones in the triangle, and another button to open a print dialogue. Figure 2 shows the opening screen with all the buttons and the ternary diagram with the symbols of beach ball representing the different focal mechanisms for any earthquake.
The various motions of the fault are represented on what is known as a beach ball. The regions of compression indicate a first motion of up and are …
In summary, The conversation is about studying beach-ball diagrams and getting help with understanding how to determine the direction of the small line, the strike line for oblique faults, and determining up and down in the diagrams.
Figure 2 shows the opening screen with all the buttons and the ternary diagram with the symbols of beach ball representing the different focal mechanisms for any earthquake.
Learn to draw a beach ball. This step-by-step tutorial makes it easy. Kids and beginners alike can now draw a great looking beach ball.
Seismologists refer to the direction of slip in an earthquake and the orientation of the fault on which it occurs as the focal mechanism. They use information from seismograms to calculate the focal mechanism and …
Return a beach ball as a collection which can be connected to an current matplotlib axes instance (ax.add_collection). beachball Draws a beach ball diagram of an earthquake focal mechanism.
4 'Beach Balls' We established earlier that you can represent focal mechanisms using 'beach ball' diagrams. Using a simple model, faulting will occur on planes, 45 from the maximum and minimum compressive stresses. It follows that the maximum compressive (P)
These diagrams are called focal mechanism diagrams, or sometimes "beach-ball" diagrams. These circular diagrams shown in the following figure are able to illustrate the strike of a plane with respect to North and …
Beachball Plot . The following lines show how to create a graphical representation of a focal mechanism.

Variations In Volleyball Court Diagrams. The volleyball court is a specific and standardized playing area, but there are still some variations in the diagrams. For example, beach volleyball courts are slightly different from indoor courts in regards to size and layout. Beach volleyball courts measure 16m by 8m, with a minimum of 9m clearance on ...

What type of fault does this beach ball diagram describe ? Draw a block diagram of this fault. Use your clear plastic lower hemisphere bowl to answer the following questions. 1e.) Find the strike and true fault dip angle of the two possible fault plane solutions for #1 above.
The "beach ball" diagrams of focal mechanisms can give information about the type and orientation of earthquakes such as the tsunami triggering earthquake suffered by Sumatra. In the San Francisco Bay Area, there are several kilometers of separation between the San Andreas Fault and the Hayward Fault, creating a wide rupture zone.
When beach-balls present four equally sized quadrants in a "top-down" view like the one in the above diagram, strike-slip faulting is represented. Rotated beach-balls with a white quarter in the center represent normal …
A focal mechanism, or "beachball", is a graphic symbol that indicates the type of slip that occurs during an earthquake: strike-slip, normal, thrust (reverse), or some combination. …

What's the beach ball metaphor? For the beach ball metaphor to be effective, it's a good idea to talk about visualization. As psychologists McCurry and Hayes explained in their study "Clinical and experimental perspectives on metaphorical talk", creating mental images helps patients recall metaphors later on. That way, they can use …
