The largest instrumentally recorded earthquake in the Gulf exposed a blind spot that Florida property owners, developers, and their counsel cannot afford to ignore: catastrophic stress on Florida buildings does not always come in the form of a named storm.
On June 8, 2026, a magnitude 6.1 earthquake struck the Gulf near the coast of Cuba, the largest instrumentally recorded earthquake in the Gulf since seismic monitoring began in 1950. Buildings swayed, offices were evacuated, and many residents along the east coast of Florida, from Miami-Dade to Jacksonville, felt the ground shake. Although no tsunami followed and reported structural damage was limited, this event exposed a blind spot that Florida property owners, developers, and their counsel cannot afford to ignore: catastrophic stress on Florida buildings does not always come in the form of a named storm.
Florida property owners have grown accustomed to preparing for wind, storm surge, floods, and torrential rain. Far less attention is paid to earthquakes, sinkholes, tornadoes, hail, and non-tropical flooding, each of which can place unexpected stress on buildings not designed with those forces top of mind and can trigger deficiencies in buildings that were not otherwise known, expose design failures, and create an urgency for both insurance claims and subsequent litigation.
Non-Hurricane Triggers of Latent Defects
Seismic activity is the clearest example. Florida’s building code accounts for wind loads, not seismic forces, meaning even a moderate earthquake can reveal weaknesses in curtain wall systems, structural connections, or foundations that were already marginal. Sinkholes, driven by Florida’s karst limestone geology, remain a persistent threat, particularly in Central Florida, where subsurface voids can undermine foundations without warning. Non-tropical flooding, like the record rainfall that flooded South Florida in June 2024, can intrude through building envelopes and waterproofing systems that were never stress-tested for such volumes of water. Tornadoes and hail, while more localized, can cause roofing and envelope failures that mimic, mask, or trigger latent construction defects.
The Litigation and Coverage Disputes That Follow
When one of these events strikes a building already carrying undisclosed or unresolved construction defects, the resulting disputes become considerably more complex. Property owners and associations must move quickly to document existing conditions and distinguish damage caused by the event from pre-existing defective construction, the same causation issue that arises in the hurricane context under Chapter 558, but often without the benefit of established precedent or adjuster experience with these less common events.
Insurance coverage disputes frequently follow close behind. Carriers may dispute whether an earthquake, flood, or other peril is covered at all, particularly where policies contain earthquake or flood exclusions requiring separate endorsements, or anti-concurrent causation language that can bar coverage entirely when a covered peril combines with an uncovered one, such as pre-existing defective construction, to cause a loss. Sinkhole claims carry their own statutory framework under Florida law, requiring specific testing protocols and reporting before a claim is compensable. Developers and contractors, in turn, may find themselves defending Chapter 558 claims while simultaneously litigating with their own carriers over defense and indemnity obligations.
Practical Risk Mitigation Strategies
Property owners, associations, and developers can take several concrete steps to reduce their exposure. First, maintain thorough documentation, including engineering reports, maintenance logs, and photographs, well before any event occurs. This documentation is often the deciding factor in causation disputes. Second, engage structural engineers and consultants immediately following any seismic event, unusual flooding, or storm damage, regardless of whether a hurricane is involved. Prompt inspection preserves evidence and can help prevent inadvertent waiver of construction defect claims. Third, review insurance policies regularly with counsel or a broker to confirm earthquake, flood, and sinkhole coverage matches the property’s actual risk profile, rather than assuming a standard property policy responds to every peril. Fourth, avoid rushing to remediate before conditions are documented and/or before consulting counsel. Well-intentioned repairs can inadvertently compromise evidence needed to prove a defect claim.
The June earthquake was a reminder that Florida’s catastrophic risk profile extends beyond hurricane season. Property owners, associations, and developers who build readiness plans around all forms of catastrophic stress, not just named storms, will be far better positioned when the next unexpected event occurs.
