The eruption of the volcano near Tonga on January 15 put the entire planet on alert.

The volcano South-East People, in the South Pacific, caused an explosion that was heard as far away as the United States, and caused waves of more than a meter that hit the coast of Tonga.

As of Monday, local authorities have not confirmed any deaths, but communications are at a standstill, making it difficult to establish the scale of the destruction.

Several countries, including Japan and Chile, issued tsunami alerts.
