Live seismic activity in Hampshire, UK
Below is a a set of bitmaps generated by drumplot from data collected at Güralp Systems' test vault in Wolverton. They are updated automatically every ten minutes, and show seismic activity over the last 24 hours. The plot on the left of each pair (or above, on smaller screens) comes from a digital surface sensor, whilst the right-hand (or below) plot was measured by a borehole sensor and digitizer.
The red mark indicates the time when the image was updated, and marks the boundary where today's data is overwriting yesterday's data. Note that the time is in UTC (= GMT), so you may have to add 1 hour for BST.

The sensors installed at Wolverton are a CMG-3TD triaxial weak motion digital instrument (120 s − 50 Hz range) and a CMG-3TB triaxial borehole instrument (360 s − 50 Hz range.) with attached downhole CMG-DM24 digitizer. Broadband data at 1 sample/s for all three axes is collected in real time and sent over a VSAT link between the vault and Güralp's facility in Aldermaston (a distance of around 6 km.)
The Wolverton vault is used as a test location for equipment. Sometimes disturbances can be seen when people enter the vault to change units.
Vertical component data from the surface (left or above) and borehole instruments.
North/south component data from the surface and borehole instruments.
East/west component data from the surface and borehole instruments.
