AGU, 79 (47), conducted using seismic waves generated by artificial seismic sources is called the seismic wave exploration.Term 4.Single-point measurement: Measurement conducted using one seismometer. H/V spectrum is the spectral ratio of ground motion in the horizontal and vertical directions obtained in single-point measurement.Term 5.Seismic zoning: A map expression of the seismic hazard and damage of buildings, taking into consideration the ground conditions. The ground conditions include the geomorphological classification that are small-scale undulations that may be difficult to be shown clearly on 1:50,000 scale topographic maps.Term 6.SN ratio: Ratio of the intensities of signal strength to background noise.Term 7.ACT protocol: Autonomous cooperative data transfer (ACT) protocol was developed to stably transfer data for the Metropolitan Seismic Observation network (MeSO-net). Protocol is a set of rules and procedures to mutually transfer information.Term 8.XML: General-use data descriptive language suitable for handling various data on the internet.
