Abstract

ABSTRACT

A description and classification is given for those later events in seismograms of refraction–and wide angle reflection shooting which travel nearly parallel and at constant time intervals behind the first arrivals and which are frequently observed in field surveys. Multiple events with the velocity of the uppermost layer may be caused by multiple ‐reflections and certain velocity conditions or by ‐conversions. In addition to these types multiple events with the velocity or may be caused by reflected refractions or by reflected diving waves. The different types will be distinguished mainly by means of travel time–and amplitude‐considerations.
