A QGIS Python plugin for the visualization of earthquake hazard data profiles.
Data sources are listed (as file paths) in the attribute table of a point layer. Only data of selected points (records) will be plotted.
Two types of data info can be visualised, by choosing the relevant source field:
- layer info: density, velocities and Q values can be plotted against depth
- strong motion data: time vs. velocity plots
Input file format
For layer info, data in the source files are organised as in the example:
vp and vs rho depth thk till 1100 km only changed
thk(km) rho Vp(km/s) Vs(km/s) Qp Qs depth(km) layer

For strong motion data, source files are as in the following example:
