'GlyphSea': A New Way to Visualize Vector Data

submitted by: btolo

Researchers at the San Diego Supercomputer Center (SDSC) and other organizations within the University of California, San Diego, have developed a novel way to encode and display vector data that clearly shows magnitude and direction. This new visualization technique may help seismologists to accurately analyze ground movements for an earthquake, measure magnetic turbulence in deep space, or allow medical researchers to study areas such as blood flow and nutrient absorption.

Magnitude 8 Earthquake Simulation Along the San Andreas Fault

submitted by: btolo
The earthquake simulation starts to the north, near Parkfield, and ruptures southeastward. The colors (white depicts the most intense shaking) show the amplitude of the waves as they are generated on the fault and radiate to surrounding areas. The number in the top right corner lists the time since the initiation of the earthquake. Notice how areas such as Ventura, Los Angeles, San Bernardino, and the Coachella Valley generate some of the strongest (and longest duration) shaking, due to...

Strong shaking in Los Angeles expected from southern San Andreas earthquake

submitted by: video_collector
The southernmost San Andreas fault has a high probability of rupturing in a large (greater than magnitude 7.5) earthquake sometime during the next few decades. New simulations show that the chain of sedimentary basins between San Bernardino and downtown Los Angeles form an effective waveguide that channels Love waves along the southern edge of the San Bernardino and San Gabriel Mountains. Earthquake scenarios with northward rupture, in which the guided wave is efficiently excited, produce...
