Seismos / Helis / Tremor Plots


Each region contains links (underlined) for seismograms / helicorders that are relevant to that region. If the item is not underlined there is no information for that area yet. Use the navigation links below to go directly to a region, or you can also use the navigation on the right hand side. All links open in this page.
Regions, and countries within the regions, are as approximately as defined by the United Nations Country Grouping. The site is continually being update so why not bookmark this page so you can return to it easily.

WORLDWIDE

Live Internet Seismic Server Helicorders from around the world as thumbnails on a single page. Each thumbnail leads to s full image.
Seismogram Displays Click on a red seismogram icon or a region on list at right. There may be additional links in the list that are NOT on the map. Below the map ate links to areas in the United States and other world wide seismogram facilities
Center For Engineering Strong Motion Data This does lead to small graphics of specific quakes, but also leads to the data for those quakes if you have the capabilities to deal with that. Effectively what appears to provided is a SAC-ASCII file. The QVS Data program can read these but I have not tested it on this type of file yet. I think the headers may not be the same.
Realtime Network Stations List Stations for _REALTIME virtual network 1960/01/01 00:00:00 to 2599/12/31 23:59:59 (1873 stations). This is useful if you are searching for an active station near somewhere since all active stations are in this one list and you can use your browser ‘find’ facility to search.
Realtime Network Stations Map The mapping of the above. Beware, this can take a while to download all 1873 stations even on broadband.
QUACK Web Footed Interface This is the front page where you need to select Explore Data. The you select your network, station and channel and if there is data click on the day you want (Julian [ordinal] days) and then click on – Webicorder of selected time series data – to see the seismogram for the day.
