Links to seismographs and helicorders worldwide split into 4 main regions in addition to Global. (Use the link on the right to return to QVS Data if you came from there.)
Seismographic sites offering access to virtually worldwide coverage systems.
All European countries, Scandinavia, the Middle East including Iran
Northern America, including Canada, Greenland, Central and Southern America and the Caribbean etc but excluding the US.
The United States of America and Hawaii
GEOFON Live Seismograms
On this page you can load 24-hour monitor seismogram plots from various near-real-time stations of the GEOFON network. The data from these stations are normally transmitted in real-time over Internet to the GEOFON Data Centre. The GIF plot files from the current day are updated every 10 minutes.
An alternative is to use the GEOFON page I have provided here which has the names of the stations which you may find easier to use.
Live Internet Seismic Server
Helicorders from around the world as thumbnails on a single page. Each thumbnail leads to s full image.
Earthquakes from the Past 24 Hours
Seismograph stations which are transmitting their data live, via the Internet, to the Albuquerque Seismological Laboratory. Click a red dot to see the heli plot for that station.
Seismic Network Operations
Something like the interactive map above, Covers the ANSS backbone and the Global Seismic Network (GSN) Stations. Click on a triangle to go to the station. On the page you arrive at there are details of: the heli-plot.
- The site: sometimes with photos
- The instrumentation: Locations, channels tc
- Plots as PDFs
- The Heli-plot
- 2 Technical tabs
- Links to other relevant areas
Bear in mind that you may not be able to get seismo plots from all the channels, and only one will be shown on these pages. See quack query below.
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. Then 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.
- Not strictly a ‘Global’ network as there are few outside the US of A – The NetQuakes network
