Response to the following question:
1. Suppose an earthquake were to occur along the Japanese trench near the island of Hokkaido in the western Pacific The waves from this event are recorded by seismographs in San Francisco Order the time of arrival of seismic wave types using number flj to indicate the first wave arrival to [5] for the last wave arrival. Use all 5 numbers
Rayleigh wave (surface wave)
Love wave (transverse surface wave).
P-wave (compressional-dilatational body wave)
