The bounds are 1.5 and 1.8. Locations where the ratio is less than 1.5 are plotted in blue. Locations where the ratio is greater than 1.8 are plotted in red. Because these are large plots, an example is shown below, but the entire plot set can be downloaded from the following link:<br /> <br /> [[http://hypocenter.usc.edu/research/ucvm/cs_cca/cca_cs_169_ratio_maps.tar.gz Ratio Vp/Vs Maps]]<br /> <br /> Raw CSV data showing each point plotted and the value of those points can be found using the following link:<br /> <br /> [[http://hypocenter.usc.edu/research/ucvm/cs_cca/cca_cs_169_ratio_csv.tar.gz Ratio Vp/Vs CSV]]<br /> <br /> Below is a summary of each slice and the minimum and maximum Vp/Vs for each layer. Each layer is 500m deep. So layer 1 is surface (0m), layer 2 is 500m depth, etc.<br /> <br /> NOTE: THE LOWEST AND HIGHEST VALUES BELOW ARE THE LOWEST AND HIGHEST OUTSIDE OF THE BOUNDARIES. SO WHEN IT SAYS LOWEST 1.8, THAT DOESN'T MEAN THE LOWEST RATIO FOUND IN THE ENTIRE LAYER WAS 1.8, IT MEANS THAT THE LOWEST ABNORMAL RATIO FOUND WAS JUST SLIGHTLY ABOVE 1.8 (I.E. THIS LAYER CONTAINS NO VALUES THAT GO BELOW 1.5).<br /> <br /> &lt;pre&gt;<br /> METADATA FOR CCA MODEL VP/VS RATIO:<br /> <br /> 1.386 min at (-120.67, 37.99), 2.277 max at (-120.44, 34.89) for depth

The bounds are 1.5 and 1.8. Locations where the ratio is less than 1.5 are plotted in blue. Locations where the ratio is greater than 1.8 are plotted in red. Because these are large plots, an example is shown below, but the entire plot set can be downloaded from the following link:<br /> <br /> [[http://hypocenter.usc.edu/research/ucvm/cs_cca/cca_cs_169_ratio_maps.tar.gz Ratio Vp/Vs Maps]]<br /> <br /> Raw CSV data showing each point plotted and the value of those points can be found using the following link:<br /> <br /> [[http://hypocenter.usc.edu/research/ucvm/cs_cca/cca_cs_169_ratio_csv.tar.gz Ratio Vp/Vs CSV]]<br /> <br /> Below is a summary of each slice and the minimum and maximum Vp/Vs for each layer. Each layer is 500m deep. So layer 1 is surface (0m), layer 2 is 500m depth, etc.<br /> <br /> NOTE: THE LOWEST AND HIGHEST VALUES BELOW ARE THE LOWEST AND HIGHEST OUTSIDE OF THE BOUNDARIES. SO WHEN IT SAYS LOWEST 1.8, THAT DOESN'T MEAN THE LOWEST RATIO FOUND IN THE ENTIRE LAYER WAS 1.8, IT MEANS THAT THE LOWEST ABNORMAL RATIO FOUND WAS JUST SLIGHTLY ABOVE 1.8 (I.E. THIS LAYER CONTAINS NO VALUES THAT GO BELOW 1.5).<br /> <br /> &lt;pre&gt;<br /> METADATA FOR CCA MODEL VP/VS RATIO:<br /> <br /> 1.386 min at (-120.67, 37.99), 2.277 max at (-120.44, 34.89) for depth

Too low or too high of a ratio is scientifically inaccurate and can cause instabilities within the wave propagation simulation codes.<br /> <br /> == Maps of Surface ==<br /> <br /> {|<br /> |[[File:Cca cs vp surface.png|400px]]<br /> |[[File:Cca cs vs surface.png|400px]]<br /> |[[File:Cca cs vp vs ratio surface.png|400px]]<br /> |}<br /> <br /> == Vp/Vs Ratios Lower Than 1.6 Data From UCVM ==<br /> <br /> The image below shows any location in which the Vp/Vs ratio is lower than 1.6 from UCVM.<br /> <br /> [[File:All below ratio map.png|500px]]<br /> <br /> Most of the locations seem to be in the desert and very few actually fall within the CyberShake bounding box.<br /> <br /> Map slices at each layer (500m depth spacing) are also available showing where Vp/Vs falls below 1.6.

Vp/Vs ratio was plotted for each layer (500m depth) within the CCA model. The bounds are 1.5 and 1.8. Locations where the ratio is less than 1.5 are plotted in blue. Locations where the ratio is greater than 1.8 are plotted in red. Because these are large plots, an example is shown below, but the entire plot set can be downloaded from the following link:<br /> <br /> [[http://hypocenter.usc.edu/research/ucvm/cs_cca/cca_cs_169_ratio_maps.tar.gz Ratio Vp/Vs Maps]]<br /> <br /> Raw CSV data showing each point plotted and the value of those points can be found using the following link:<br /> <br /> [[http://hypocenter.usc.edu/research/ucvm/cs_cca/cca_cs_169_ratio_csv.tar.gz Ratio Vp/Vs CSV]]<br /> <br /> Below is a summary of each slice and the minimum and maximum Vp/Vs for each layer. Each layer is 500m deep. So layer 1 is surface (0m), layer 2 is 500m depth, etc.<br /> <br /> NOTE: THE LOWEST AND HIGHEST VALUES BELOW ARE THE LOWEST AND HIGHEST OUTSIDE OF THE BOUNDARIES. SO WHEN IT SAYS LOWEST 1.8, THAT DOESN'T MEAN THE LOWEST RATIO FOUND IN THE ENTIRE LAYER WAS 1.8, IT MEANS THAT THE LOWEST ABNORMAL RATIO FOUND WAS JUST SLIGHTLY ABOVE 1.8 (I.E. THIS LAYER CONTAINS NO VALUES THAT GO BELOW 1.5).<br /> <br /> &lt;pre&gt;<br /> METADATA FOR CCA MODEL VP/VS RATIO:<br /> <br /> 1.386 min at (-120.67, 37.99), 2.277 max at (-120.44, 34.89) for depth

(500m depth) within the CCA model. The bounds are 1.5 and 1.8. Locations where the ratio is less than 1.5 are plotted in blue. Locations where the ratio is greater than 1.8 are plotted in red. Because these are large plots, an example is shown below, but the entire plot set can be downloaded from the following link:<br /> <br /> [[http://hypocenter.usc.edu/research/ucvm/cs_cca/cca_cs_169_ratio_maps.tar.gz Ratio Vp/Vs Maps]]<br /> <br /> Raw CSV data showing each point plotted and the value of those points can be found using the following link:<br /> <br /> [[http://hypocenter.usc.edu/research/ucvm/cs_cca/cca_cs_169_ratio_csv.tar.gz Ratio Vp/Vs CSV]]<br /> <br /> Below is a summary of each slice and the minimum and maximum Vp/Vs for each layer. Each layer is 500m deep. So layer 1 is surface (0m), layer 2 is 500m depth, etc.<br /> <br /> NOTE: THE LOWEST AND HIGHEST VALUES BELOW ARE THE LOWEST AND HIGHEST OUTSIDE OF THE BOUNDARIES. SO WHEN IT SAYS LOWEST 1.8, THAT DOESN'T MEAN THE LOWEST RATIO FOUND IN THE ENTIRE LAYER WAS 1.8, IT MEANS THAT THE LOWEST ABNORMAL RATIO FOUND WAS JUST SLIGHTLY ABOVE 1.8 (I.E. THIS LAYER CONTAINS NO VALUES THAT GO BELOW 1.5).<br /> <br /> &lt;pre&gt;<br /> METADATA FOR CCA MODEL VP/VS RATIO:<br /> <br /> 1.386 min at (-120.67, 37.99), 2.277 max at (-120.44, 34.89) for depth

&lt;/pre&gt;<br /> <br /> == Vp/Vs Ratio Data ==<br /> <br /> The Vp/Vs ratio was plotted for each layer (500m depth) within the CCA model. The bounds are 1.5 and 1.8. Locations where the ratio is less than 1.5 are plotted in blue. Locations where the ratio is greater than 1.8 are plotted in red. Because these are large plots, an example is shown below, but the entire plot set can be downloaded from the following link:<br /> <br /> [[http://hypocenter.usc.edu/research/ucvm/cs_cca/cca_cs_169_ratio_maps.tar.gz Ratio Vp/Vs Maps]]<br /> <br /> Raw CSV data showing each point plotted and the value of those points can be found using the following link:<br /> <br /> [[http://hypocenter.usc.edu/research/ucvm/cs_cca/cca_cs_169_ratio_csv.tar.gz Ratio Vp/Vs CSV]]<br /> <br /> Below is a summary of each slice and the minimum and maximum Vp/Vs for each layer. Each layer is 500m deep. So layer 1 is surface (0m), layer 2 is 500m depth, etc.<br /> <br /> NOTE: THE LOWEST AND HIGHEST VALUES BELOW ARE THE LOWEST AND HIGHEST OUTSIDE OF THE BOUNDARIES. SO WHEN IT SAYS LOWEST 1.8, THAT DOESN'T MEAN THE LOWEST RATIO FOUND IN THE ENTIRE LAYER WAS 1.8, IT MEANS THAT THE LOWEST ABNORMAL RATIO FOUND WAS JUST SLIGHTLY ABOVE 1.8 (I.E. THIS LAYER CONTAINS NO VALUES THAT GO BELOW 1.5).<br /> <br /> &lt;pre&gt;<br /> METADATA FOR CCA MODEL VP/VS RATIO:<br /> <br /> 1.386 min at (-120.67, 37.99), 2.277 max at (-120.44, 34.89) for depth

Vp/Vs ratio was plotted for each layer (500m depth) within the CCA model. The bounds are 1.5 and 1.8. Locations where the ratio is less than 1.5 are plotted in blue. Locations where the ratio is greater than 1.8 are plotted in red.

<p>Davidgil: /* Vp/Vs Ratio Data */</p> <hr /> <div>In order for the CyberShake simulations to be successful and stable, the Vp/Vs ratio needs to be calculated. Too low or too high of a ratio is scientifically inaccurate and can cause instabilities within the wave propagation simulation codes.<br /> <br /> == Maps of Surface ==<br /> <br /> {|<br /> |[[File:Cca cs vp surface.png|400px]]<br /> |[[File:Cca cs vs surface.png|400px]]<br /> |[[File:Cca cs vp vs ratio surface.png|400px]]<br /> |}<br /> <br /> == Vp/Vs Ratio Data ==<br /> <br /> The Vp/Vs ratio was plotted for each layer (500m depth) within the CCA model. The bounds are 1.5 and 1.8. Locations where the ratio is less than 1.5 are plotted in blue. Locations where the ratio is greater than 1.8 are plotted in red. Because these are large plots, an example is shown below, but the entire plot set can be downloaded from the following link:<br /> <br /> Raw CSV data showing each point plotted and the value of those points can be found using the following link. <br /> <br /> Below is a summary of each slice and the minimum and maximum Vp/Vs for each layer. Each layer is 500m deep. So layer 1 is surface (0m), layer 2 is 500m depth, etc.<br /> <br /> NOTE: THE LOWEST AND HIGHEST VALUES BELOW ARE THE LOWEST AND HIGHEST OUTSIDE OF THE BOUNDARIES. SO WHEN IT SAYS LOWEST 1.8, THAT DOESN'T MEAN THE LOWEST RATIO FOUND IN THE ENTIRE LAYER WAS 1.8, IT MEANS THAT THE LOWEST ABNORMAL RATIO FOUND WAS JUST SLIGHTLY ABOVE 1.8 (I.E. THIS LAYER CONTAINS NO VALUES THAT GO BELOW 1.5).<br /> <br /> &lt;pre&gt;<br /> Layer 1 done: highest 2.276874, lowest 1.385986<br /> Layer 2 done: highest 2.282521, lowest 1.452511<br /> Layer 3
