Save the result as a new clipped shapefile and run that new one through the JavaScript program by modifying which shapefile the script loads. PLAXIS 3D CEV21 Tutorial 09: Earthquake analysis of a building.p3dlog This exercise requires a PLAXIS 3D Ultimate license for Dynamics features. Post-earthquake and tsunami 3D laser scanning forensic investigations. Then select the PGV shapefile as the input vector layer and the borders shapefile as the clip layer. Select Vector > Geoprocessing Tools > Clip.
Once you have both the PGV shapefile and the simplified world borders shapefile loaded together in QGIS you can clip one using the other. Once you have downloaded that you can unzip it and load it into QGIS. Among the properties that are well modeled by.
The simplified world borders shapefile they have works well to give a general outline of the coast. Modeling Dynamic Rupture in a 3D Earthquake Fault Model by R. The website contains some good simplified coastline shapefiles. However, a detailed version might take a long time to perform the clipping. Using a simplified version will allow the clipping operation to run fairly quickly, but won't give a highly accurate coastline. You can find highly detailed versions or simplified versions. You can use QGIS to clip the polygons.įirst download a shapefile that represents the coastline. The shakemap doesn't distinguish between the land and ocean, so for areas along the coast, like this Northridge quake, it can be helpful to clip the shapefile to the land border to provide geographic context. Crucial factors that control rupture behavior in. We find that the rock properties affect the locations and amount of slip produced in our simulated large earthquakes.
#3d earthquake code
I'll be converting the PGV map to a 3D model, but the same steps apply for any of the other shapefiles in the archive. use a finiteelement computer code to perform 3D dynamic earthquake rupture simulations. You can read about these various measurements. PGA is peak ground acceleration, PGV is peak ground velocity, and MMI is Modified Mercalli Index. The shapefile download of an earthquake contains multiple shapefiles that represent different measurements of shaking. The specific shapefile download that we'll use is here. On the page for a specific earthquake you can find the shapefile downloads under Downloads > GIS File > Shape Files. This tutorial will map the Southern California Northridge earthquake of 1994. For this tutorial we'll focus on a few major historical earthquakes. The scenarios are modeled hypothetical earthquakes that might occur as worst-case scenarios along major fault lines. You can find both historical earthquakes as well as scenarios.
#3d earthquake archive
Any large earthquake can be found in their archive of shakemaps. The USGS uses a worldwide network of sensors to automatically produce shakemaps of all major earthquakes that occur throughout the world.
