The risk of ‘cascading’ natural disasters is on the rise
Any doubts? Recent quakes from Eastern Turkey show that public is not that much aware of that. Let me explain with an example.
Sharing one key example from active tectonic area: Belasitsa (Κερκίνη) Mts.
This mountain is one of the prime examples of a horst structure:
@8 March 1931 southern fault ruptured, generating catastrophic damages (BG only, still AI translators do a good job).
Landslides, debris flows. We manage to quickly document what is happening in “moderate” heavy rainfall.
It looks like that the whole Mountain is collapsing. Lets have a look at some features:
Location of one of the largest slides is this:
~ 2 km2 landslide, affecting N slopes of Belasitsa Mt. Source: GE imagery.
Of course, with modern imagery this is easy to detect. But, these mass-wasting processes are well documented on old BG maps:
And, as expected 😒 responsible BG agencies are not aware of that. Check this from Geozashtita-Pernik. (link is OK, just Goverment service is not working properly. Maybe that is part of society-related care?)
Yet, we can be thankful for BigBrother satelite surveliance:
