Mr. Illes said the new wall in Kolontar — which will be incorporated permanently into the town's landscape, with a bike path planned on its ridge — would withstand a flood even if the second reservoir burst.
Measurements taken in the past 24 hours showed no further movement of cracks on the northern wall, which experts have said is bound to collapse.
Health authorities warned the local population, as well as cleanup and construction crews, that the amount of red sludge dust in the air exceeded safe limits and said protective gear should be used.
Pablo Gorondi reported from Budapest.
