Sentence examples for sustained occurrence from inspiring English sources

These analyses also suggest that the sustained occurrence of Acheulean handaxe technologies in regions such as Europe and the Indian subcontinent resulted from dispersals by African hominin populations.

A sustained occurrence of more than 20,000 aftershocks have been ceaselessly stressing local earthquake refugees, about 125,000 families are still live in temporary houses due to remaining earthquake debris.

This would also support the idea that the widespread and sustained occurrence of the Acheulean in Europe and the Indian subcontinent was the result of the same dispersal process from Africa [8], which on the basis of current evidence, intensified during the terminal Early Pleistocene and early Middle Pleistocene.
