If you've lived through even a tiny earthquake it's much like if you've experienced a solar eclipse: even when short and mild, they elicit an otherworldly body-terror. The people living on that peninsula right now are stressed out in a way most of us have never experienced.
Hmm. I've done both. Tiny earthquake is no big deal. A big one, different story.
I have experienced big earthquakes in the former circumstances, and the sensation was confusing, until the earthquakes stopped you were not sure whether your building level is still firmly attached to its base, or it has started to travel independently towards an unavoidable fall.
