Following Tomas post let’s stay a little longer on the Corinth Canal. The 6 km long famous Corinth Canal despite being an amazing feat of engineering, since it was constructed 120 year ago, it’s also a geology field trip favourite because it is basically a MEGA TRENCH.
More than 40 faults can be identified some of them offsetting the entire sedimentary column, whereas others are confined within the lower sediments. Therefore, this photo shows a very nice example of an active and inactive fault within the same outcrop. You can rarely see something like that and this is a unique site where everybody can see and comprehend it.

Faults also die.
It shows also that faults die. This is very important because there are numerous faults in the crust, however the majority of them are inactive (e.g. can not give an earthquake today, but they did so in the past). So for earthquake geologists their first major goal is to identify which of the faults they map are active (e.g. can generate earthquakes today and represent seismic sources).

eto lang ba?

wala bang inactive na faults line ha kasi sabi nila merong inactive at active na faults line hello duh?

active faults are structure along which we expect displacement to
occur

What are the most dangerous and hazardous, active fault or inactive fault? Why?
Christoph Grützner | September 14, 2017|10:54 (UTC)
The highest hazard comes from those that move fast (high slip rate), those that are long enough to produce strong earthquakes (say, at least 10 km for aM6.0 earthquake, at least 30 km or so for a M7.0 and so on), and those that are close to densely populated areas and infrastructure.
Then of course you also have to think about landslides and rockfalls that may be triggered by the earthquakes, and of course there are the subduction zones that may cause tsunamis.
