Ash Fall Effects: How volcanic ash affects Hilo Airport's infrastructure and operations
Volcanic ash fall poses significant challenges to the infrastructure and operations of Hilo Airport, located on the Island of Hawaiʻi, which is in close proximity to active volcanoes like Kīlauea. When volcanic ash is emitted during eruptions, it can travel considerable distances, settling on surfaces and infiltrating systems critical to airport functionality. The abrasive nature of volcanic ash, composed of sharp, glass-like particles, accelerates wear and tear on runways, taxiways, and aircraft surfaces. This degradation reduces friction coefficients on runways, compromising braking efficiency and increasing the risk of accidents during takeoff and landing. Regular maintenance and cleaning become essential to mitigate these effects, but the frequency and intensity of ash fall can overwhelm standard protocols.
Ash fall also severely impacts airport operations by disrupting air traffic control systems and navigation equipment. Volcanic ash can infiltrate sensitive electronics, causing malfunctions in radar systems, communication devices, and instrumentation used for flight guidance. Visibility is another critical concern, as ash clouds reduce visibility to dangerous levels, making it unsafe for aircraft to operate. Airlines often cancel or divert flights during periods of heavy ash fall, leading to significant delays and economic losses. The airport must rely on real-time volcanic activity monitoring and coordination with meteorological agencies to make informed decisions about closures or resumptions of operations.
The physical infrastructure of Hilo Airport is further threatened by the accumulation of volcanic ash on buildings, terminals, and parking areas. Ash can clog drainage systems, leading to water pooling and potential flooding during rainfall. Additionally, the weight of wet ash on rooftops poses structural risks, necessitating immediate removal to prevent collapse. Cleaning efforts are labor-intensive and costly, requiring specialized equipment and personnel trained to handle hazardous materials, as volcanic ash can be harmful when inhaled or ingested.
Aircraft themselves are highly vulnerable to volcanic ash, which can cause engine failure, damage avionics, and erode exterior surfaces. Hilo Airport must enforce strict protocols for aircraft inspection and maintenance during ash fall events. Engines, in particular, require thorough cleaning or replacement of filters to prevent contamination. Airlines operating from Hilo often incur additional costs for de-ashing procedures and may need to reroute flights to less affected airports, further straining resources.
Long-term exposure to volcanic ash can also lead to corrosion of airport infrastructure, including metal components of buildings, vehicles, and ground support equipment. Corrosion inhibitors and protective coatings may be applied, but their effectiveness diminishes under continuous ash exposure. The airport’s sustainability and resilience depend on proactive measures, such as designing ash-resistant structures and investing in advanced filtration systems for indoor facilities. Collaboration with volcanologists and emergency management agencies is crucial to develop strategies that minimize the impact of ash fall on Hilo Airport’s operations and ensure the safety of passengers and staff.

Emergency Closures: Conditions under which Hilo Airport may close due to volcanic threats
Hilo International Airport, located on the Island of Hawaii, operates in a region prone to volcanic activity due to its proximity to active volcanoes like Kilauea and Mauna Loa. While the airport is designed to function under normal conditions, emergency closures may occur when volcanic threats escalate to levels that compromise safety. The primary conditions that could lead to such closures include significant ashfall, volcanic smog (vog), lava flow encroachment, and seismic activity. These factors are closely monitored by authorities, including the Federal Aviation Administration (FAA), the National Weather Service (NWS), and the U.S. Geological Survey (USGS), to ensure timely decisions regarding airport operations.
One of the most immediate threats to Hilo Airport is volcanic ashfall. Ash can severely damage aircraft engines, reduce visibility, and pose health risks to passengers and staff. If ashfall reaches levels deemed hazardous—typically when ash accumulation exceeds 1-2 millimeters or visibility drops below 3 miles—the airport may be closed temporarily. The NWS issues Volcanic Ash Fall Advisories to guide such decisions, and airlines may also suspend flights independently based on their safety protocols. Ashfall from nearby eruptions, such as those from Kilauea, can disrupt operations even if the eruption itself is not directly adjacent to the airport.
Volcanic smog (vog) is another condition that may prompt airport closures, though less frequently. Vog, a mixture of sulfur dioxide gas and other volcanic pollutants, can reduce air quality to unhealthy levels, particularly for individuals with respiratory conditions. While vog is less likely to cause a full airport closure, it may lead to flight delays or cancellations if air quality indices (AQI) reach hazardous levels. The Hawaii Department of Health monitors vog levels and issues advisories that can influence airport operations.
Lava flow encroachment poses a direct physical threat to Hilo Airport, though this scenario is less common due to the airport's distance from active volcanic vents. However, if lava flows advance toward critical infrastructure, such as runways or navigation systems, the airport would be closed immediately. The USGS provides real-time updates on lava flow trajectories, allowing authorities to make informed decisions. In such cases, closures would likely be prolonged until the threat is mitigated and repairs can be made.
Seismic activity associated with volcanic eruptions can also lead to emergency closures. Strong earthquakes or continuous tremors may damage airport infrastructure, including runways, terminals, and navigation equipment. If structural integrity is compromised, the airport must close until inspections and repairs are completed. The USGS monitors seismic activity and issues alerts that help airport authorities assess risks and take appropriate action.
In all cases, the decision to close Hilo Airport due to volcanic threats is guided by a multi-agency approach, prioritizing public safety and operational feasibility. Passengers are advised to monitor flight statuses, follow advisories from official sources, and stay informed about volcanic activity when traveling to or from Hilo. While closures are rare, they are a necessary precaution in a region where volcanic activity is an ever-present reality.
