Krakatau and the architecture of vulnerability: Colonial governance, risk perception, and disaster impact
[...]
Colonial intervention, settlement patterns, and reliance on maritime economies created significant structural vulnerabilities for the people inhabiting the island, which would serve only to magnify the impacts of Krakatau’s eruption.

The timeline of the Krakatau eruption begins in early May of 1883, when the captain of the Elisabeth, a German warship, observed and documented a massive cloud of ash and dust rising above the island (National Centers for Environmental Information, 2017). Soon thereafter, reports of tremors and explosive sounds were heard across western Java and Sumatra, originating from the Krakatau volcanic caldera, which had remained dormant for over two centuries (Carita, 2025).

Social vulnerability, especially to natural hazards, is influenced by a population’s ability to “respond to, cope with, recover from, and adapt to hazards,” oftentimes shaped by a community’s experience with those hazards (Cutter, 1996). Scholarly research on risk perception illustrates that communities interpret and perceive hazards through trust in institutions, familiarity with environmental cues (such as the significant activity before a large volcanic eruption), and with deference to cultural experiences (Slovic, 1987; Renn, 2008).
