Mercury, it may not have rained as much as the recent deluges in the time you have lived there, but, the natives will certainly have had experience of this severity in the past. Why, Oh Why, are they allowed to make such dangerous constructions? Looking at the remains of the "retaining" wall, ( which obviously didn't retain, ) even if it had been built using poured, reinforced concrete, those totally inefficient buttresses, which stopped part-way up the outside of the wall, would NEVER have been sufficient to hold back the hydraulic pressure which obviously built up behind it. There is NO substitute for good old Clerks of Works, ever.
