We are pleased to announce the release of the Global Stacks, a data product generated by stacking up to a million event-windowed seismograms.
The Global Stacks product is based on stacking short-term to long-term averages (STA/LTA) in different frequency bands for vertical broadband data (1990-2012) available from the IRIS DMC. Long period versions include vertical and horizontal component data. Figures and ZIP files of the STA/LTA stacks as well as stacks of envelope functions and vespagrams and lists of quality controlled traces are available on the product and supplement pages:

IRIS Data Services and Education and Public Outreach are conducting a contest to create a new poster based on the wealth of stacks available in this product. We would like your help in making an iconic image to be featured on an IRIS poster:
