During the earthquake drill, Quezon City tested their contingency plan for earthquake showcasing various scenarios namely: evacuation involving high density population, collapse structure search and rescue, fire suppression, hospital surge, and camp management.
Therefore, the collapse structure filled the void such that only minimal collapse, possibly only sagging, occurred near the surface, while greater disruption occured deeper in the strata.
The solutional sinkholes are formed by epigene processes and collapse structures represent failure into an underlying void, which may have formed by hypogene or epigene processes.
These results can be used to non-invasively evaluate karst features as potential geohazards within the region and within other evaporite facies, where upward stoping collapse structures could cause significant geohazards threats.
