Earthquake: Is an Injury Arising From an Act of Nature Compensable?

An act of nature is, in essence, a natural disaster such as flooding, landslides, lightning, freezing, tsunamis and earthquakes. These types of events are considered “force majeure,” or causes outside the parties’ control that could not be avoided by exercising due care. Generally, an injury arising from an act of nature is a non-compensable injury. If the employee can prove exposure to a risk greater than that of a member of the general public, however, the injury may be found to be compensable.

As an example, if a large earthquake caused buildings in the area to topple and ceilings to collapse, an employee at a school district might be injured. Some employees might suffer heart attacks or post-traumatic stress. These types of injures would not be proximately caused by employment. But if the school district building was the only building that collapsed during an earthquake, or it was found that the building was defective, the claim would be compensable.

Because of the intervention of a human agency (the defective building) placing the employee in harm’s way, a special risk or danger was created that may not have occurred if the employee was in a different location. This could mean the employment was the proximate cause of injury.

According to Gwen Hampton’s “Workers’ Compensation Benefits Manual,” “If no special aspect of the employment was involved, the naturally occurring disaster would appear to be the proximate cause of injuries sustained at the worksite, as well as those sustained by the general public.”

A related question has been posed about injury during an earthquake drill. An employee’s participation in a safety drill arises from employment and occurs in the course of employment. The employee is under the control and direction of the employer, rendering a benefit to the employer. An injury suffered during a drill would be a compensable injury. If an employee were acting up, joking around or horseplaying during a drill and then injured him or herself, however, there is a defense to such an injury under the law.

Following are several examples of injuries occurring during natural disasters.

The rule of thumb from the California Workers’ Compensation Claims and Benefits Volume One, Eleventh Edition: “If the employment subjects the employee to an increased risk compared to that of the general public in the vicinity, the injury is compensable. If the cause of injury is an intervening human agency or instrumentality of the employment, the injury is compensable.”
