Latest seismic drums and RSAM/SSAM images

These images are used to appraise the frequency of local earthquakes and the level of ground tremor at a volcano.

The production of these images is computationally intensive so there is no guarantee that the images are available for every site, nor that the style of the images will stay the same. A typical set of images for a volcano monitoring site are:

The above URLs point to images for the seismometer at location 10 at site HBAZ in the AK network. As long as we need to produce images for this site and there is a seismometer at the location then the URL is valid. Depending on your purpose it may make sense to store the 'network', 'site', and 'location' values as configuration parameters.

For more information about each seismic site, including opening and any closing dates. see our DELTA database. You may also wish to view the seismic network maps or read about how we interpret these images.
