Before using this website, please note the following:

This is a Beta version. As such, it is under development and will likely be modified in the near future. The Shaking Layers site is expected to be generally reliable and available but while it is in Beta the site is only monitored for failure during business hours.

Shaking Layers will only be automatically generated in the first instance. Automated versions have not been reviewed by seismologists. Shaking Layers may be updated by seismologists following significant earthquakes using evolving scientific information.
