|Inside the crater|
The much-smaller Krakatau (Krakatoa, if you are old-fashioned) eruption of 1883 in Indonesia created a 30-metre-high tsunami that killed 36,000 people, as well as pyroclastic flows that travelled 40 kilometres across the surface of the seas killing 1,000 people on nearby islands.
|Nice walking, too!|
Luckily, while we still cannot predict earthquakes, eruptions are much easier to predict, a month or so out from the event.
