Plainfield and Joliet, IL Tornado, Aug 1990

Plainfield and Joliet, IL Tornado, Aug 1990

On August 28, 1990, from 3:15 to 3:45 p.m., the strongest tornado in northern Illinois in greater than 20 years struck the towns of Plainfield, Crest Hill, and Joliet in Will County. As a result of the storm's impact phase, 302 persons were injured (28 fatally). This report summarizes an investigation of injuries and deaths that resulted from the tornado's impact.
The tornado's path was up to -mile wide and 16.5 miles long; wind speeds were greater than 260 mph. National Weather Service criteria for issuing a tornado warning were not satisfied until the tornado had already touched the ground. Electrical power service to 65,000 customers and phone service to 10,000 residences were severed; in addition, the tornado destroyed three schools, a church, many businesses, 106 apartment units, and 470 single-family dwellings. The estimated cost of damages was $200 million (Will County Emergency Services Disaster Agency, unpublished data, 1990). Because no warning was provided, few persons sought a tornado shelter.
The investigation included a review of 350 emergency-room and inpatient medical records from eight hospitals to identify injuries sustained during the impact phase and the postimpact phase of the tornado. Ninety percent of affected persons were white and lived in predominantly residential subdivisions in three communities (1). Because many persons who were rendered homeless by the tornado relocated with relatives living in the area, more than 84% of the victims who sought medical care at hospitals could be contacted for telephone interviews.
An impact-related injury or death was defined as an injury or death caused by the direct mechanical effects of the tornado. Postimpact injuries were defined as injuries that would not have occurred in the absence of the tornado and that occurred within a 48-hour period following the tornado (e.g., from walking through the debris or cleaning up debris).
While most impact-related deaths occurred instantaneously, four persons with impact-related injuries died 2-8 weeks after the tornado. Of these four, one man died 8 weeks later from complications of chest trauma suffered during the impact phase.
Most (221 (63%) of 350) victims were treated initially at one of the eight hospitals; several of the more severely injured were transferred to tertiary-care facilities in other areas. Because the disaster occurred simultaneously with the change of work shifts for the nursing staff, approximately twice as many persons were available as would be expected in an average staffing pattern for that hospital; many physicians and off-duty nurses also volunteered services.
Of the 28 persons who died from impact-related injuries, eight were less than 20 years of age (range: 1 month-69 years; mean: 34 years); 14 were male (Table 1). Seven persons died in one large apartment complex; eight, in vehicles; five, in schools; four, in houses; and two, outside. Three persons died at one high school, where greater than or equal to 10 students crouched against the only hallway wall that did not collapse and, therefore, may have been protected from fatal or severe injury.
