Hi Chewyturk,
A few questions in there
All new builds have to follow strict regulations which are in place to safeguard against earthquakes. Another fact to bear in mind is that all older builds have already been subjected to earthquakes, some bigger than others but certainly within my time here at least one that made buildings move and flex. There was no damage to any buildings (even the 'hand built' traditional really old ones!).
Calis covers a large area, and it is too sweeping to say it is 'swamp land' - true there are some poor areas, but that is not the case for the most part. On one of our constructions we actually sold the excavated soil to garden centres, such was the quality of the area.
There is also another school of thought that argues that properties built on soil (or even poor land) cope with earth tremors better than properties built directly onto rock. This is because the transfer of tremor from ground to building is direct through rock, a less dense substrate can dissipate some of the energy. I'm not entirely convinced on that one, but it does make some sort of logical sense.
In saying all that, correct construction will prevent any problems. We have discussed on the forum before the fact that a well built property on poorer land will fare better than a poor quality build on good land.
I think the bottom line is that nearly all properties can cope effortlessly with a fair sized wobbler - if a huge one comes they will probably all cope equally well or badly.
As for Tasyaka, you can buy (relatively) a lot of apartment for your money, but it is fairly devoid of bars and restaurants (I await the Tasyaka members backlash
) so you will need transport if you fancy popping out for an efes or two.
I hope that helps in one way or another.
