solvis 1.3.1

Analysis of opensha modular solution files.

Solvis

A library to support the analysis of OpenSHA inversion solution data.

Solvis is used in the geospatial investigation of the New Zealand National Seismic Hazard Model inversion sources and rates. It supports both individual inversions and the composite model.

Features / Goals

Solvis is used in the analysis of OpenSHA Modular Fault System Solution files.

From a typical modular OpenSHA Inversion Solution archive, we can produce views that allow deep exploration of the solution and rupture set characteristics.

• Select a set of ruptures matching:
  • one or more parent faults
  • one or more corupture fault names
  • the vicinity of one or more named nzshm-common locations
  • defined regions
• Create new region polygons
• Determine geometric features, such as dip direction relative to strike bearing
• Calculate the geometries of solution and fault surfaces projected onto the Earth surface
• Calculate fault sections with their rupture rates and solution slip rates
• Generate Magnitude-Frequency Distribution (MFD) histogram data
