An earthquake beneath a volcanic island produces P-waves and S-waves, which travel through surrounding solid rock towards a region being investigated. Which station record would provide evidence that the waves travelled through solid material in that region?
P-waves are recorded on routes through the region, but S-waves are not.
P-waves and S-waves are recorded on routes that do not pass through the region.
Neither P-waves nor S-waves are recorded on routes through the region.
P-waves and S-waves are both recorded on routes that pass through the region.
