Structural plate tectonics and colonial seismic monitoring gaps deepen Japan’s tsunami vulnerability: A case study in underfunded early-warning systems and Indigenous Pacific hazard knowledge

Marginalized voices, particularly those of Indigenous communities and low-income coastal populations, are often excluded from seismic risk assessments despite being the most vulnerable to disasters. For example, in Japan, rural fishing communities along the Tōhoku coast had long observed subtle changes in marine life and landforms that could signal impending seismic activity, but these observations were not systematically recorded or integrated into official warning systems. Similarly, in Pacific Island nations, the voices of women—who often play central roles in community-based disaster preparedness—are rarely amplified in global seismic research. Centering these perspectives could lead to more inclusive and effective early-warning strategies that address the unique needs and knowledge of affected communities.
The 2011 Tōhoku disaster was not merely a failure of seismic science but a systemic collapse of knowledge systems, economic priorities, and governance structures that prioritized growth over resilience.
The original framing’s focus on 'ancient faults' obscures how colonial-era scientific models dismissed Indigenous Pacific knowledge—like Māori *whakapapa* or Tongan *fale* traditions—which could have provided critical early warnings. Historically, such systems were systematically marginalized, as seen in the 1960 Valdivia earthquake, where Mapuche oral histories of 'earthquake lights' were ignored until after the fact. Japan’s post-war economic boom further exacerbated the problem by diverting funds from seismic monitoring to industrial expansion, leaving critical fault-line research underfunded until catastrophic failure forced reform. Cross-culturally, seismic activity is often understood through spiritual and ecological lenses, such as the Māori concept of *Tāne* or Tongan *Fonua*, which frame disasters as part of a broader cosmic balance rather than isolated natural hazards. Future modelling must integrate these perspectives, combining Indigenous temporal frameworks with scientific data to create more adaptive early-warning systems. The trickster perspective reveals how human systems—like centralized disaster response models—actually create the conditions for failure, exposing the absurdity of treating seismic risks as inevitable rather than preventable. Solutions must center marginalized voices, reallocate economic priorities, and establish Global South-led research networks to build truly resilient disaster preparedness strategies.
