The magnitude of the earthquake was 6. The death toll was 36,417. In the years before the 1883 eruption, seismic activity around the Krakatoa volcano was intense, with earthquakes felt as far away as Australia. The combination of pyroclastic flows, volcanic ash, and tsunamis associated with the Krakatoa eruptions had disastrous regional consequences. In the aftermath of the eruption, it was found that Krakatoa had almost entirely disappeared, except for the southern third.
