It is difficult to predict the path of volcanic lava.

Lava from the Kilauea volcano in Hawaii threatened to reach communities on the Big Island and authorities declared a state of emergency. But is there an effective way to stop the lava and save the houses in its path?

Sicilians have always been threatened by Mount Etna, the volcano located in the northeast of the Italian island.

In 1669, the residents of the town of Catania faced the destructive advance of the lava «armed with picks and shovels and protecting themselves from the heat with wet sheepskins», according to the historical account, and opened a breach to cut off its path.

But the inhabitants of the neighboring town of Paterno did not like the idea, because they believed that the diversion of the burning lava was aimed directly at their own community.
