This page displays the seismic traces recorded in the last 24 hours at some OSU-CT seismic stations, located on the Island of Vulcano. HNZ indicates the vertical component of the accelerometer while EHZ the vertical component of the velocimeter. Each screen shows 4 hours of recording. The screens corresponding to the different time bands can be selected from the table above. Each line represents 15 minutes of recording and each minute is separated by vertical lines. Times are expressed in UTC. Therefore to get the local time you need to add 1 hour when standard time is in effect or 2 hours when daylight saving time is in effect.
