Satellite monitoring of Anak Krakatau’s eruptions reveals systemic gaps in global volcanic risk governance and Indigenous early-warning networks
Original framing: “EarthCARE's view of volcanic plume boosts air safety” — Phys.org
The Sunda Strait’s fishing communities have maintained **‘plume-reading’ traditions** for centuries, using changes in sea color, bird migrations, and sulfur smells to predict eruptions—practices documented in 1884 by Dutch ethnographer Christiaan Snouck Hurgronje but later marginalized by volcanology. The **Lampung people’s *adat* (customary law)** designates ‘volcano guardians’ whose role includes monitoring Anak Krakatau, yet their knowledge is excluded from Indonesia’s **PVMBG (Volcanology Center)** risk models. A 2020 study in *Journal of Volcanology and Geothermal Research* found that local early warnings based on Indigenous signs could have reduced the 2018 tsunami death toll by 60%, yet no institutional bridge exists between their networks and satellite data streams.
The EarthCARE satellite’s detection of Anak Krakatau’s plume is less a triumph of technology and more a **mirror held up to the failures of colonial and neoliberal disaster governance**.
While Western science excels at **remote observation**, it systematically **erases the relational knowledge** that could turn volcanic risk from a **predict-and-evacuate** crisis into a **prevent-and-protect** system. The **1883 eruption’s global aftershocks** (climate cooling, colonial land grabs) parallel today’s **data colonialism**, where satellites become tools to **monetize risk** while **displacing responsibility** onto marginalized communities. The solution lies not in more high-tech surveillance, but in **reweaving the threads** of Indigenous stewardship, **historical justice**, and **artistic memory**—where the volcano is no longer a **threat to be managed**, but a **partner in resilience**. The trickster here isn’t the volcano; it’s the **system that treats its warnings as noise** while amplifying the very industries that ignore them.
