We are stuck in the village, unable to travel out to fish
Off the coast of Papua New Guinea's Manus Province, a rare undersea volcano known as Titan Ridge has awakened from its century-long silence, blanketing island shorelines with pumice stone and severing the maritime lifelines that small fishing communities depend upon entirely. What geology produces in moments, human communities must endure across weeks and months — and for villages like Baon, where a boat is not a luxury but the difference between sustenance and starvation, the slow accumulation of volcanic rock has become an existential siege. The crisis reminds us how thinly drawn the line is between the rhythms of nature and the fragility of lives built upon the sea.
- A volcano that erupts once or twice per century has chosen this generation, sending pumice so thick across island waters that boats sink into it like vessels swallowed by quicksand.
- Fishing has stopped, trade routes are severed, and medical emergencies now have no safe passage — entire communities are stranded not by storm or conflict, but by floating rock.
- Drinking water, always scarce on remote islands, is disappearing faster than expected as residents forced away from the pumice-choked sea turn to their freshwater reserves simply to bathe.
- Beneath the surface, the pumice smothers coral and starves the marine ecosystem of sunlight, threatening the very food web these communities have relied upon for generations.
- Papua New Guinea's government has acknowledged the crisis and launched assessments, but for villages already waiting in silence — listening to the volcano rumble through the night — official process offers little immediate comfort.
In early May, the undersea volcano Titan Ridge, roughly 125 kilometres from Manus Province in Papua New Guinea, erupted with such violence that the explosions registered from space. The lava, cooling rapidly in seawater, produced enormous quantities of pumice — the lightweight, porous rock that floats — and within weeks it had accumulated so densely along island coastlines that the surrounding waters became impassable.
In Baon village, one of the worst-affected communities, Councillor Raymond Simeku watched the pumice thicken day after day. For islanders who rely entirely on boats to fish, trade, and reach medical care on neighbouring islands, the blockage was not an inconvenience — it was a slow emergency. One boat that attempted to push through described the water as moving through quicksand and nearly sank. No one could leave. Food supplies began to run low.
The water crisis proved equally urgent. Unable to bathe in the pumice-covered sea, residents began drawing on their limited freshwater reserves for washing, accelerating consumption at a dangerous rate. New water tanks were needed, but there was no way to bring them in. Meanwhile, the pumice itself was reshaping the ecosystem beneath it, blocking sunlight and killing the coral and fish that sustain these communities over the long term.
Scientists at the Rabaul Volcanic Observatory noted that events of this scale occur only once or twice per century. The volcano remained active, and whether the pumice would continue to pile up or eventually disperse remained unknown. Prime Minister James Marape acknowledged the disruption and announced government assessments were underway to prepare for worst-case scenarios — but for the people of Baon, sitting on their islands and listening to the distant rumble of Titan Ridge through the night, the waiting had already become its own kind of suffering.
In early May, an undersea volcano called Titan Ridge, sitting about 125 kilometres south-east of Manus Province in Papua New Guinea, began erupting with such force that the explosions were visible from space. The eruptions sent massive quantities of pumice stone—the lightweight, porous rock that forms when lava cools rapidly in water—washing onto the coastlines of nearby islands. Within weeks, the accumulated pumice had become so thick and dense that it choked the waters around fishing villages, trapping residents who depend entirely on boats to survive.
In Baon village, one of the hardest-hit communities, Councillor Raymond Simeku watched the pumice build up day after day with a sense of helplessness he had never experienced before. "I was so shocked," he said. The village sits on a remote island where boats are not a convenience but a lifeline. Fishermen use them to catch food. Traders use them to reach markets. When the pumice arrived, it made the water impassable. One boat that attempted to leave nearly sank, the pilot describing the sensation as moving through quicksand. Days passed with no one able to leave. The food supplies that sustained the community began to dwindle.
The immediate crisis extended beyond hunger. Baon's residents rely on boats to reach health clinics on other islands, and with maritime routes blocked, medical emergencies became potentially catastrophic. But the most pressing problem was water. The village's freshwater supplies, always limited on a remote island, began to run dangerously low. Residents, unable to bathe in the sea because of the pumice, started using their drinking water for washing. The consumption accelerated. "Our water supplies are actually running down because so much water has been consumed just for bathing," Simeku explained. The village needed more water tanks, but there was no way to bring them in.
The pumice itself posed a broader ecological threat. The thick, stagnant coverage blocks sunlight from reaching the water below, killing coral, fish, and other marine life that communities depend on. What had seemed like a natural disaster isolated to a few villages was beginning to reshape the entire ecosystem that sustained them. Steven Saunders from the Rabaul Volcanic Observatory noted that such an event occurs only once or twice in a century. The volcano remained active, though with reduced intensity, and whether the pumice would continue to accumulate on the islands or be dispersed by wind and current remained uncertain.
Prime Minister James Marape acknowledged the crisis in a statement, saying the government understood that the volcanic discharges were "affecting movement, traffic, and creating uncertainty amongst our people." He announced that urgent assessments were underway to determine how best to respond and to prepare communities for worst-case scenarios. But for Baon and other trapped villages, the assessment phase offered little immediate relief. Residents sat on their islands, listening to the distant rumble of the volcano at night, watching the pumice continue to build, and waiting for help that had not yet arrived.

Why does pumice from an undersea volcano end up on the shore? I thought underwater eruptions would just stay underwater.
Pumice is different from other volcanic rock—it's so full of air pockets that it floats. When the lava cools rapidly in seawater, it traps gas inside, and the whole thing becomes buoyant. The ocean currents and waves carry it to shore, sometimes hundreds of kilometres away.
So the villages are trapped because they can't navigate through it. But couldn't they just wait for it to disperse?
In theory, yes. But these are communities where a boat trip to the market or to a clinic isn't optional—it's survival. Every day the pumice blocks the water, people go without food they would normally catch or trade for. And if someone gets seriously ill, there's no way to reach a doctor. Waiting isn't really an option.
The water shortage seems like the most immediate threat. Why would using drinking water for bathing be necessary?
Because the pumice makes the sea unusable for washing. Normally you'd rinse off in saltwater. But with the pumice coating everything, that's not possible. So people resort to using their freshwater reserves, which are already scarce on a remote island. It's a cascade—one problem creates another.
The volcano is still active but reduced. Does that mean it could get worse again?
That's the uncertainty everyone is living with. The expert said it could pick up again at any time. Right now the pumice production has slowed, but the wind and currents are still moving what's already there. No one knows if the islands will be buried or if nature will eventually clear it away.
What does the government actually do in a situation like this?
They're still assessing. The Prime Minister said they want to understand what's happening and prepare for worst-case scenarios, but that's different from having a plan. These are remote communities. Getting supplies to them, clearing the water, finding alternative routes—none of that is simple or quick.
