摘要:

Barometric lows over large bodies of water produce the maximum microseisms which decrease with increase in distance from the storm area. Tropical hurricanes, as well as winter storms, may be roughly traced by changes in amplitudes as the storms approach the stations in their paths. Geological units seem to have considerable influence on microseismic amplitudes. Local barometric pressure changes have no influence on the microseisms of nearby stations. Storms over land which seldom have deep lows do not produce appreciable microseisms on ordinary teleseismic records. Although such records yield valuable information on microseisms, they are not adequate for a complete study of these phenomena.
