Virtual Networks at the IRIS DMC

A virtual network is a group of stations and/or seismic networks, representing an affiliation that goes beyond the traditional bounds of seismic networks to represent an umbrella organization or initiative. Virtual networks associate to recording stations and seismic networks either indefinitely or for some limited period of time. It is a grouping system that reflects growing partnerships between seismic institutions to undertake large projects and act as a single, newly formed entity. The virtual network naming system allows these traditional networks to have their data represented under the auspices of one or more of these initiatives.

The number of virtual networks is growing daily, as is the number of recording stations within them. For this reason, we have created this web page to provide the latest list of virtual networks so that users may explore them further and understand the details of who is involved and what recording stations are incorporated into them. The adopted standard is to indicate a virtual network by a leading underscore ('_'), thereby removing ambiguity as to the meaning of a tag entry.

The current list of virtual networks are listed below. Click on the links to explore details on a specific virtual network. The user also has the option to draw back VND files from the detail pages, available in Microsoft Excel(TM) and CSV formats.
