Opinion: Living in the Shadow of Semeru’s Fury

By: A concerned observer of Indonesia’s fragile balance between nature and human resilience

Introduction

When Mount Semeru roared once again in November 2025, the skies above East Java turned gray, and the ground trembled with a reminder that nature does not negotiate. For centuries, Semeru—known locally as “Mahameru,” the Great Mountain—has been both a sacred symbol and a looming threat. Its eruptions are not anomalies but part of a cycle that defines life around its slopes. Yet every time ash clouds rise, the same questions return: Why do communities remain so close to danger? What lessons have we learned—or failed to learn—from past disasters? And what does Semeru’s fury reveal about our relationship with the environment?

The Historical Weight of Semeru

Mount Semeru is not just another volcano. It is the highest peak on Java, standing at 3,676 meters, and it carries immense cultural and spiritual significance. In Javanese cosmology, Semeru is seen as the axis of the universe, a sacred pillar connecting the earthly and the divine. This symbolism has kept people tied to its slopes, even as eruptions have claimed lives and destroyed livelihoods.

Historically, eruptions from Semeru have been frequent but varied in intensity. Villages have been buried under pyroclastic flows, rivers clogged with volcanic debris, and farmland rendered useless by layers of ash. Yet, despite these recurring tragedies, the population around Semeru continues to grow. The fertile volcanic soil is irresistible to farmers, and the cultural bond is too strong to sever. This paradox—danger and dependence—defines the Semeru story.

The November 2025 Eruption

The latest eruption was not the largest in Semeru’s history, but it was significant enough to disrupt daily life across East Java. Ash clouds reached tens of kilometers into the sky, forcing residents to wear masks and stay indoors. Schools closed, flights were rerouted, and emergency shelters filled with families fleeing the advancing pyroclastic flows. The government’s disaster response was swift, but the scale of displacement highlighted how vulnerable communities remain.

What struck me most was not the eruption itself but the reaction of the people. Many residents expressed resignation: “This is Semeru. It erupts. We live with it.” That stoic acceptance is admirable, but it also raises uncomfortable questions. Should resilience mean enduring repeated trauma? Or should resilience mean rethinking settlement patterns, infrastructure, and preparedness in ways that reduce risk rather than normalize it?

Resilience or Fatalism?

Indonesians are often praised for their resilience in the face of natural disasters. From earthquakes to tsunamis, the archipelago has endured countless calamities. But resilience can sometimes blur into fatalism. When communities accept disaster as inevitable, they may stop demanding systemic change. Living near Semeru is not just a matter of faith or tradition—it is also a matter of policy, economics, and governance.

The government provides relocation programs, but many villagers refuse to move. The soil near Semeru is too fertile, the water too abundant, and the cultural ties too deep. Relocation often means poverty, disconnection, and loss of identity. In this sense, resilience is not just about surviving eruptions—it is about surviving the social and economic consequences of leaving ancestral land.

The Environmental Message

Semeru’s eruption is not just a geological event; it is an environmental message. Volcanoes remind us that the Earth is alive, dynamic, and indifferent to human ambition. In an age of climate change, where human activity accelerates environmental instability, Semeru’s fury feels like a warning. We cannot control the mountain, but we can control how we live around it.

The ash that blankets villages is destructive in the short term but nourishing in the long term. Volcanic soil is among the most fertile in the world, which is why communities return again and again. But this fertility comes at a cost. Every harvest is shadowed by the possibility of destruction. The question is not whether Semeru will erupt again—it is when.

Policy and Preparedness

Indonesia has made progress in disaster preparedness. Early warning systems, evacuation drills, and community education have saved lives. Yet gaps remain. Infrastructure near Semeru is often inadequate, shelters overcrowded, and communication inconsistent. The November 2025 eruption revealed both strengths and weaknesses: while many were evacuated safely, others were caught off guard, trapped by blocked roads or misinformation.

Policy must go beyond emergency response. It must address long-term settlement planning, economic alternatives, and cultural preservation. Relocation programs must be designed not as forced displacement but as opportunities for sustainable living. Otherwise, people will continue to return to danger zones, driven by necessity and identity rather than choice.

The Human Dimension

Behind every eruption are human stories. Families who lose homes, children who miss school, farmers who watch their crops vanish under ash. These stories deserve more than sympathy—they deserve structural support. Too often, disaster relief is short-term: food, shelter, medical aid. What is missing is long-term investment in rebuilding lives, not just infrastructure.

“We do not fear Semeru. We fear being forgotten after the eruption.” — A villager in Lumajang

That statement captures the essence of the challenge. The eruption is dramatic, but the aftermath is quieter and more painful. When media attention fades, communities are left to rebuild with limited resources. True resilience requires sustained commitment, not just emergency aid.

Global Reflections

Semeru’s eruption is not just Indonesia’s problem—it is a global reminder. Around the world, communities live near volcanoes, fault lines, and floodplains. The balance between risk and reward is universal. Fertile soil, abundant water, and cultural heritage often coexist with danger. The challenge is to find ways to honor tradition while embracing safety.

In this sense, Semeru is a metaphor for humanity’s broader struggle with nature. We build cities on coasts vulnerable to rising seas, we farm land prone to drought, we expand into forests that fuel climate instability. Semeru’s eruption is a localized event, but its lessons are global: respect nature, plan wisely, and never confuse resilience with resignation.

Conclusion: Living with Semeru

As I reflect on the November 2025 eruption, I am struck by the duality of Semeru. It is both destroyer and provider, sacred and terrifying, eternal and unpredictable. Living with Semeru means living with contradiction. It means accepting danger while cherishing fertility, honoring tradition while confronting modern realities.

My opinion is simple: resilience must evolve. It cannot remain a passive endurance of repeated trauma. It must become an active pursuit of safety, sustainability, and dignity. Communities near Semeru deserve more than admiration for their courage—they deserve policies that protect their lives and livelihoods. The mountain will erupt again. The question is whether we will be ready, not just to survive, but to thrive in the shadow of its fury.

Final Thoughts: Between Reverence and Risk

Mount Semeru embodies the paradox of human existence in volatile landscapes. Reverence for its sacred role in Javanese cosmology coexists with the undeniable risk of living in its shadow. The November 2025 eruption is not an isolated event but part of a continuum that forces us to confront uncomfortable truths: our attachment to land, our dependence on fertile soil, and our willingness to normalize danger.

In my opinion, the time has come to redefine resilience. It should not mean simply enduring ash and rebuilding after each eruption. It should mean creating systems that allow communities to thrive without sacrificing safety. This requires bold policy, empathetic governance, and a willingness to challenge cultural inertia. It also requires global solidarity, because the lessons of Semeru resonate far beyond East Java.

The mountain will erupt again. That is certain. What remains uncertain is whether we will continue to repeat the same cycle of disaster and recovery, or whether we will finally embrace a future where resilience is proactive, not reactive. Living with Semeru does not have to mean living in fear. It can mean living with respect, preparedness, and dignity. But that choice is ours, not the mountain’s.
