Περίληψη
Στις ορεινές περιοχές ένας κίνδυνος που ενσκήπτει είναι οι απότομες βραχώδεις κλιτύες, οι οποίες σε μεγάλο βαθμό ελέγχονται από πτώσεις βράχων. Αν και οι πτώσεις βράχων χαρακτηρίζονται από μικρούς όγκους ολισθαίνουσας μάζας πετρωμάτων σε σύγκριση με τους υπόλοιπους τύπους κατολισθήσεων, μπορούν να προκαλέσουν σημαντικές βλάβες σε κτήρια, υποδομές εξαιτίας της ξαφνικής και της πολύ γρήγορης κίνησής τους. Βασική παράμετρος στην κατανόηση της διεργασίας που οδηγεί στην εκδήλωση πτώσεων βράχων αποτελεί η μελέτη των κυριότερων αιτιών που επηρεάζουν την ευστάθεια της κλιτύος. Η εξέλιξη της βραχώδους κλιτύος μπορεί να συσχετίζεται με πολλά γενεσιουργά αίτια όπως τεκτονικά, γεωμορφολογικά, σεισμικά, κλιματολογικά ή ανθρωπογενή. Η παρούσα εργασία παραθέτει σε σύνοψη μεθοδολογίες που σχετίζονται με το φαινόμενο της πτώσης βράχων. Επιπλέον χρησιμοποιεί παραδείγματα από την περιοχή της Βόρειας Πελοποννήσου ώστε να καταστεί σαφής η χρησιμότητα των μεθόδων ανάλυσης του φαινομένου στην ελληνική επικράτεια. Συλλέγοντας δεδομένα και παράγοντας θεματικούς χάρτες και συνδυάζοντας την υπαίθρια παρατήρηση με την τηλεπισκόπηση, είναι δυνατή η απόδοση βέλτιστων αποτελεσμάτων τα οποία μπορούν να ενταχθούν σε τεχνικές σκιαγράφησης της επικινδυνότητας και τη λήψη προστατευτικών μέτρων.
