Our hearts go out to the victims of the quakes and tsunami in Sulawesi, Indonesia. Methods to provide aid are provided via the Jakarta Post link below.
Of geological interest was liquefaction (Japanese - “ekitaika” 「液体化」). This can happen during quakes where the water table is shallow and is of concern in Yatsushiro and certain areas of Kumamoto City. A rare video of its effects was captured, showing buildings sliding as if on slime or simply being swallowed by the earth, available at the second link. A friend recently asked for advice on purchasing a house regarding earthquake faults; I answered that those are unavoidable but to be careful of the soil type. - William
