Lawrenz would have found a fine case study for his work this week in events that started with a volcanic eruption in the South Pacific and led to dramatic results—political, social and economic—far away in Peru.

The eruption was spectacular, and spectacularly devastating for the tiny island, wiping out entire villages and crushing infrastructure in the nation of just 105,000 people. In the immediate aftermath, several countries issued alerts to warn their populations of potential tsunamis—including Ecuador and Chile, Peru’s neighbors to the north and south—more than 6,500 miles away from Tonga.
