WebJan 1, 2004 · In refraction seismology, the relevant seismic arrivals are the direct wave and the “head wave” (critically refracted arrival). For ease of interpretation, the head wave is identified most easily when it is the first event on a seismogram. An understanding of the direct arrival and the head wave can be obtained by examining Figure 1.
