Four seismic stations recorded the event (P-wave arrival indicated by the vertical red line). Match the seismograms to the station that recorded themSeismogram 1[ Choose ]Seismogram 2[ Choose ]Seismogram 3[ Choose ]Seismogram 4[ Choose ]>>

The sudden and temporary vibration set up on the earth surface that ranges from a faint tremor to a wide motion generated by the sudden release of energy stored in the rock beneath the earth surface is termed an earthquake. From the point of origin beneath the earth surface the wave energy disseminates in all directions. The point beneath the earth surface where the earthquake waves are developed is termed as the focus of the earthquake and the point immediately above the focus where the earthquake waves first arrive is termed epicentre. The primary wave of the earthquake reached the surface first and the closest seismic station was experienced the first occurrence with the help of a seismograph.Here there are four seismic stations around the seismic activity, from the seismogram of primary wave we can identify each seismic station. The WLK station is close by the red star that represents the location of the earthquake. Next closer is MBD, then RXZ and JVQ. Therefore the seismogram 1 represents WLK, seismogram 2 represents MBD, seismogram 3 represents RXZ and seismogram 4 represents JVQ.Answer: Seismogram 1: WLK Seismogram 2: MBD Seismogram 3: RXZ Seismogram 4: JVQ
