$133 Million in Damage and a Five-Week Blackout: When Maria Closed Puerto Rico's Largest University

PRhurricaneemergency notificationmedium confidence
Confirmed Threat

Hurricane Maria struck Puerto Rico as a high-end Category 4 hurricane on the morning of September 20, 2017, causing the longest sustained blackout in U.S. history and approximately $133 million in damage to the University of Puerto Rico system. The flagship Río Piedras campus in San Juan suffered destroyed roofs, shattered windows, flooded laboratories, and the loss of an entire building housing the Department of Environmental Sciences. With island-wide telecommunications and electricity destroyed, the university could issue no SMS or email alerts; closure decisions were communicated by radio broadcasts and word of mouth over the following weeks.

[The University of Puerto Rico announced suspension of academic and administrative activities across all eleven campuses as Hurricane Maria approached as a Category 5 storm. The closure was communicated via email, the upr.edu website, and broadcast media; SMS alerts were degraded as cellular infrastructure began failing.]

UPR's pre-storm closure decision was made on September 19, 2017, the day before Maria's catastrophic landfall on the morning of September 20

[With island-wide telecommunications, electricity, and internet destroyed by Hurricane Maria, the University of Puerto Rico communicated continued closure of all campuses through radio broadcasts, particularly on WKAQ and WAPA, and through Spanish-language television where transmission could be restored. SMS, email, and the university website were inaccessible to most students for weeks.]

The post-Maria communications collapse was the most extensive blackout of any U.S. higher-education emergency in modern history
Radio became the primary mass-communication channel on the island for several weeks; battery-powered AM/FM receivers were the only functional devices in many homes
UPR officials walked from building to building on each campus to assess damage and determine which structures could be partially reopened

[The University of Puerto Rico began phased resumption of academic operations in late October 2017, more than five weeks after Hurricane Maria. Río Piedras, Mayagüez, and Humacao — the three largest campuses — sustained the most severe damage. The Department of Environmental Sciences building at Río Piedras was destroyed; biology research generators failed and cell lines were moved between buildings.]

Phased reopening began in late October 2017; some UPR campuses did not return to full operations until early 2018
An entire building housing the Department of Environmental Sciences at Río Piedras was destroyed and not replaced for years
Biology research at Río Piedras lost generator power; researchers physically moved cell lines and other samples between buildings to preserve them
Context

Background

Hurricane Maria struck Puerto Rico on the morning of September 20, 2017 as a high-end Category 4 hurricane (sustained winds of 155 mph at landfall near Yabucoa) and produced the most catastrophic U.S. natural disaster of the 21st century in terms of duration of mass-disruption: the island lost virtually all electricity, almost all cellular service, and most of its potable water for weeks to months. The University of Puerto Rico system, the island's largest higher-education institution with eleven campuses and approximately 60,000 students, suffered an estimated $133 million in damage, exceeding its $100 million insurance policy. The flagship Río Piedras campus in San Juan lost roofs and walls on multiple buildings, including the destruction of the entire structure that housed the Department of Environmental Sciences. Dormitories were without power; trees were uprooted across the campus. Biology research generators failed, forcing researchers to physically move cell lines and other samples between buildings to preserve their work. Telecommunications collapse was the defining communications challenge: with cellular service, internet, and electricity destroyed island-wide, neither SMS nor email could reach students or faculty for weeks. UPR communicated closure decisions through radio broadcasts on WKAQ and WAPA, through Spanish-language television where transmission could be restored, and through in-person assessment by administrators walking building to building on each campus. UPR began phased academic resumption in late October and early November 2017, more than five weeks after the storm; some campuses did not return to full operations until 2018. The case is uniquely significant for this archive as the most severe documented example of complete telecommunications collapse during a U.S. campus emergency, and as one of only a handful of cases in the archive from a U.S. territory.
Analysis

Key Findings

Hurricane Maria caused the most extensive telecommunications collapse of any U.S. higher-education emergency in modern history; SMS and email were inaccessible for weeks
UPR's $100 million insurance policy did not fully cover the estimated $133 million in damage across the system's largest campuses
The Department of Environmental Sciences building at Río Piedras was destroyed entirely; biology research lost generator power, forcing physical movement of samples
Radio became the primary mass-communication channel for higher-education institutions in Puerto Rico for several weeks after Maria
Phased academic resumption took more than five weeks; some UPR campuses did not return to full operations until early 2018
Outcome
No reported on-campus deaths attributable to the storm. Río Piedras and other UPR campuses remained closed for at least a month; substantial portions of the system did not reopen until late October and early November 2017. UPR's $100 million insurance policy did not fully cover the estimated $133 million in damage across the system's three largest campuses (Mayagüez, Río Piedras, and Humacao). Biological research collections and cell lines were lost when generators failed.
