1 Quarterly Journal of Engineering Geology and Hydrogeology
Geology, geomorphology and geohazards on a section of the Betic coastline, southern Spain by G. J. Hearn Quarterly Journal of Engineering Geology and Hydrogeology Volume ():qjegh January 28, 2019 © 2019 The Author(s). Published by The Geological Society of London. All rights reserved

2 The Betic Cordillera and the location of places referred to in the text.
The Betic Cordillera and the location of places referred to in the text. It should be noted that the location of Section A–A is indicative, as Silvertop (1836) did not provide a map and referred to it as a section line between Alhama and the sea at Vélez Málaga (see Fig. 4).

5 The progress of geological modelling through the Sierra Tejeda (for location of sections see Fig. 1). The progress of geological modelling through the Sierra Tejeda (for location of sections see Fig. 1). Section A–A is from Silvertop (1836), Section B–B from IGME (1972a, 1978) and Section C–C from Williams & Platt (2018). It should be noted that in Section A–A the distance from Sierra Tejeda (coincidentally where ‘C’ is shown) to Alhama is significantly underestimated compared with the distance from Sierra Tejeda to the coast.

Failed hillsides inland of the autovía. It should be noted that dimensions are very approximate. Failures shown in (a) and (d) are shown on the published 1:50 000 scale 1055 Motril geological map sheet as part of Quaternary derrubios, or debris aprons (IGME 1972b). G. J.
