The landscape of Hawaii’s Big Island continues to be shaped by one of the most active volcanoes on Earth. On June 13, 2025, Kīlauea Volcano erupted for the 25th time since December 2024, sending plumes of ash and volcanic gases high into the sky and once again alarming local communities, scientists, and health officials. This latest eruption underscores not just the raw power of Earth's geological systems, but also the increasingly urgent need to address the health and environmental impacts of persistent volcanic activity.

An Unrelenting Force: 25 Eruptions and Counting

Kīlauea’s current phase of hyperactivity has taken many by surprise, including veteran volcanologists who have monitored the volcano for decades. While the volcano has a long history of eruptive episodes, the frequency and intensity observed since December 2024 are unprecedented in recent memory.

The 25th eruption began in the early morning hours with a series of small earthquakes—a familiar precursor in the region. Within minutes, fissures opened along the East Rift Zone, releasing lava fountains as high as 100 feet. By midday, lava flows had already engulfed parts of the nearby forest and were inching dangerously close to Highway 130, a critical route for local transportation and evacuation if needed.

The Hawaii Volcano Observatory (HVO), which has been closely monitoring Kīlauea using satellite imagery, seismic sensors, and ground reports, issued a red aviation alert and urged residents in affected zones to prepare for possible evacuations. The eruption also triggered air quality warnings across multiple counties due to elevated levels of sulfur dioxide (SO₂), volcanic ash, and fine particulate matter (PM2.5).

Community Resilience Tested

Communities across the Big Island have grown accustomed to the presence of Kīlauea, but the incessant eruption activity has placed an extraordinary strain on local emergency services, healthcare systems, and residents' mental health. Many families have been forced to relocate multiple times over the last six months, often with little notice.

"I haven’t had a full night’s sleep in weeks," says Lani Kai, a lifelong resident of Puna. "The ground trembles constantly, the air burns our lungs, and we're always wondering when the next eruption will force us to run again."

Temporary shelters have been established in community centers and schools, while local charities and government programs are working to provide food, clean water, and masks to mitigate the effects of volcanic smog, or “vog”, which continues to blanket wide areas.

Health Hazards on the Rise

While the flowing lava and collapsing craters make for dramatic visuals, the less visible health impacts of Kīlauea’s eruptions are becoming a growing concern. Continuous exposure to sulfur dioxide and other volcanic gases is known to exacerbate respiratory conditions such as asthma, bronchitis, and COPD. Children, the elderly, and individuals with preexisting conditions are especially vulnerable.

According to Dr. Keoni Alapa of Hilo Medical Center, "We’re seeing a spike in ER visits related to breathing problems, headaches, and even skin irritations. The long-term consequences of repeated exposure to these volcanic emissions could be severe if the eruptions continue at this pace."

Air quality monitoring stations across the island have reported SO₂ levels exceeding World Health Organization (WHO) safety thresholds, sometimes for days at a time. These prolonged exposures can lead to chronic respiratory issues, weakened immune systems, and an increased risk of cardiovascular complications.

Environmental and Economic Impact

The environmental damage caused by the ongoing eruptions is also substantial. Several thousand acres of forest and farmland have been consumed by lava, displacing wildlife and damaging local ecosystems. The constant release of volcanic gases also contributes to acid rain, which can degrade soil quality and harm freshwater sources.

Tourism, one of Hawaii's key economic drivers, has taken a hit. Although some adventurous travelers are drawn to the spectacle of an erupting volcano, many more have canceled trips due to safety concerns and poor air quality. Local businesses, particularly in tourism-dependent areas like Volcano Village and Pāhoa, report significant drops in revenue.

“Our bookings are down by 60% compared to last year,” says Jason K., a bed-and-breakfast owner in the affected zone. “We used to have guests from around the world excited to see the volcano. Now they’re afraid to come.”

Scientific Efforts and Emergency Preparedness

The United States Geological Survey (USGS) and the Hawaii Emergency Management Agency (HI-EMA) have ramped up efforts to forecast eruptions and coordinate emergency response. Scientists are leveraging machine learning and real-time data analytics to improve eruption prediction models, while public officials are working on refining evacuation routes and distributing updated emergency preparedness guidelines.

"We are in a constant state of readiness," says HI-EMA spokesperson Moana Takai. "With the volcano showing no signs of slowing, we’re urging residents to stay informed through official channels, keep emergency kits ready, and take air quality alerts seriously."

A new mobile app launched by the University of Hawaii in partnership with the USGS allows users to track lava flow directions, air quality indexes (AQI), and seismic activity in real time. The app has already seen over 100,000 downloads since its release in early 2025.

Cultural and Spiritual Reverence

It’s important to recognize that Kīlauea holds deep cultural and spiritual significance to Native Hawaiians. According to traditional beliefs, the volcano is the home of Pele, the goddess of fire and creation. For many locals, the eruptions are not merely natural disasters but expressions of divine power that must be respected and understood, not merely feared.

"We respect the land, and we respect Pele," says Kahu Lehua, a cultural practitioner. "Yes, it’s hard. Yes, it’s dangerous. But this is her home. We live here with humility and gratitude, even when the lava flows."

Ceremonies and chants have become more frequent in affected areas, offering solace and strength to communities that are enduring the brunt of Kīlauea’s fury.

A Call to Action: What Comes Next?

As Kīlauea's activity persists, calls are growing louder for increased federal support, enhanced public health infrastructure, and sustainable relocation programs for families most at risk. Advocates are urging the U.S. Congress to expand funding for disaster relief, mental health services, and climate resilience projects that address the unique challenges posed by recurring volcanic activity.

In the long term, scientists warn that global warming and changing geological pressures may further increase the likelihood of frequent eruptions in volcanic hotspots around the world, including Hawaii. What’s happening on the Big Island could serve as a cautionary tale for other regions unprepared for the dual threats of natural disaster and health crisis.

Hawaiians are resilient. Their deep-rooted connection to the land gives them strength in the face of such adversity. But resilience must be matched with preparedness, support, and innovation if the islands are to weather what could be an era of geological upheaval.

Final Thoughts

Kīlauea’s 25th eruption since December 2024 is a stark reminder that Hawaii’s Big Island exists at the mercy of deep Earth forces. While the spectacle of lava flowing into the ocean may captivate the world, the human cost—measured in anxiety, displacement, and deteriorating health—cannot be ignored. As this story unfolds, it is essential that policymakers, scientists, and citizens alike rise to meet the challenge, not just with awe, but with action.
