Strong Ground Motion Relationship

You can now plot the relationship in a couple of different ways:

• Single Reliability (P) - This is the most traditional way of viewing the SGM relationship. The PPV is plotted against the distance to hypocentre (R) for various magnitudes. This chart uses a single reliability / probability of non-exceedance. Adjust the reliability in the control panel. Note: Probability of exceedance = 1 - Reliability.
• Single ML - Plot PPV vs. R for various reliability levels (up to 4 levels plus the 50% line). Adjust the chosen ML from the control panel.
• Single ML, R - Plot the PDF and CDF for a particular ML and R combination. Adjust the chosen ML and R from the control panel.
