When Disaster Strikes, Communication Grids Fall

Introduction

In August, the Hawaiian island of Maui was engulfed by sudden wildfires. As residents desperately tried to flee from the deadliest wildfire to hit the U.S. in over a century, they found themselves facing another devastating blow—the loss of their local telecommunications grid. With no cell phone service available, communication became impossible. Similar scenes unfolded in Canada’s Northwest Territories, where wildfires damaged communication infrastructure.

Alison Poste, an emergency management professional from British Columbia, explains, “Every disaster I’ve experienced or read about, communications are the first to go. It’s a significant challenge for those without cell phone access or other alerting tools—we simply don’t know what to do.” With the frequency and intensity of disasters like wildfires, hurricanes, and floods increasing, it is crucial to ensure that residents, first responders, and emergency managers have effective communication methods in place. Although numerous obstacles exist, various individuals, businesses, and local governments are working to overcome them.

Reliance on Cell Phones

In most communities, cell phones are the primary means of gathering and distributing information during disasters. Local governments can send essential updates via text alerts, and emergency managers used to rely on platforms like Twitter (now renamed X) to disseminate critical information. Other emergency-notification tools, such as Alertable and Everbridge, also exist. However, these resources depend on users having an active cell signal—and in the event of a fire, flood, or other disaster, cell towers and infrastructure can quickly be disabled, creating a chaotic and dangerous information bottleneck.

“Losing your phone on a normal day can be challenging,” says Leysia Palen, a professor at the University of Colorado Boulder who specializes in disaster informatics. “If we struggle with it in everyday situations, then imagine the difficulty during a disaster.” Palen explains that before the widespread use of cell phones and social media, individuals relied on various sources such as radio, neighbors, and television news to gather information during disasters. While these sources still play a role today, the near-exclusive reliance on cell phones underscores the importance of functional telecommunications grids.

Vulnerabilities and Mapping

Telecommunications networks, consisting of towers, antennas, and wires, are vulnerable at multiple points. “The grids are becoming more interdependent,” says Susanne Jul, an emergency management consultant. “A failure may not happen to my local cell tower that burned, but rather a communication center miles away, preventing us from receiving signals.” While backup generators and portable cell sites can temporarily restore service to a limited area after a disaster’s peak, creating a map of the most threatened telecommunications network locations is still a work in progress.

However, mapping efforts are complicated by the fact that detailed information about existing infrastructure is hard to come by. Private companies like AT&T and Xfinity do not disclose specific locations of their cell towers and antennas to researchers or the public. The Federal Communications Commission provides data on the percentage of cell towers experiencing outages, but this data lacks the location precision required for accurate network mapping. “Cell companies treat that data as very private,” says Seth Guikema, a professor of engineering at the University of Michigan.

Protecting Grids and Alternative Options

One proactive approach to strengthening telecommunications grids involves making them less vulnerable to disasters. Different types of disasters affect infrastructure in various ways. For instance, carriers construct cell towers capable of withstanding high winds during hurricanes. The heat and flames from wildfires typically rise upward, sparing underground fiber-optic cables but posing a threat to towers and above-ground infrastructure. Removing flammable fuel near these structures could increase their chances of survival.

When all grid-protection measures fail, communities and emergency managers must have alternative tools to navigate the loss of cellular communication. Sirens and AM radio broadcasts remain essential, while more sophisticated options also exist. However, relying on unfamiliar technologies during emergencies may hinder their usefulness. Speed is critical in life-or-death situations, and unfamiliar tools may slow down response times. Therefore, it is recommended to prioritize the use of commonly available tools, such as cell phones, during emergencies.

Human Networks and Community

During the Marshall Fire in Boulder, Colorado, atmospheric scientist Rebecca Morss found herself relying on her phone and her neighbors to navigate the state’s most destructive wildfire. Despite her expertise in weather and risk communication, Morss ultimately turned to a local friend for assistance. She explains, “We have a long history of doing this pre-cell phone. Often the first responders are the local people in the community until officials can get there. Thirty or forty years ago, that’s what people did.” As technology strives to keep up with disasters, community support and human networks remain invaluable resources.
