How To

How to use this archive - finding Vs30, Z1.0, and Z2.5

1. Within each of the geographic/project groupings below, you link into a Google Drive folder.

2. Each ReMi analysis result appears as a separate text file in your web browser, within the Google Drive interface.

3. Earthquake-monitoring site characterizations include the station code in the name of the file, so if you are looking for one of those it should be easy to find. Transect characterizations will have a site number.

4. Double-click on a file name within a folder to view or download the text file.

5. The lat/long locations of each measurement are within the text files, often along with additional location information. We are developing maps and lists to help you find sites.

6. All characterization text files have a shear-wave velocity versus depth, or Vs(z) profile. Depths and velocities are always metric, in meters and meters per second.

7. Most files give a Vs30 value; some also give Z1.0 and Z2.5 values. Some include references to the picked p-f image, and list the dispersion picks. We are in the process of populating the whole archive with those data- so let us know which sites you want us to update sooner.

8. You can determine the Vs30, and minimum possible Z1.0 and Z2.5 values from the Vs(z) profile, if the values are not given.
