75 Minutes from Threat to Evacuate: How UT Austin Cleared 50,000 People After an Al-Qaeda Hoax Call

TXbomb threatemergency notificationmedium confidence
Confirmed HoaxDetermined to be a hoax. The institutional response is documented because it reveals how the alert system performed under a perceived real threat.

On Friday morning, September 14, 2012, The University of Texas at Austin received a call at 8:35 AM CDT from a man claiming affiliation with al-Qaeda and stating that bombs were placed across campus and would detonate within 90 minutes. After consultation with the FBI and a 75-minute delay, the university issued a text alert at 9:50 AM CDT ordering immediate evacuation of every building — sending more than 50,000 students, faculty, and staff streaming away from the Forty Acres. A near-simultaneous threat targeted North Dakota State University that morning, and both incidents would become foundational case studies in campus bomb-threat response.

INITIAL ALERTSMS
Verified verbatimKUT Radio (Austin NPR affiliate) coverage citing the verbatim 9:50 AM CDT text alert sent through UT's emergency notification system107 chars
Due to threats on campus immediately evacuate all buildings get as far away from the buildings as possible.
Reached approximately 69,000 mobile users — one of the largest single-alert text-message blasts a U.S. university had executed at that point
The absence of standard punctuation between 'buildings' and 'immediately' is preserved from the SMS as sent — the message was clearly composed for character economy rather than grammatical polish
Sent 75 minutes after the 8:35 AM CDT phoned-in threat — a delay UT President Bill Powers later defended as necessary time for FBI consultation
'Get as far away from the buildings as possible' departs from the more common 'evacuate to a safe location' boilerplate, reflecting the specific nature of the threat (bombs in buildings, not an active shooter)
UPDATEEmail

All University of Texas at Austin classes have been canceled for today. Faculty, staff, and students should not return to campus until further notice. We will provide updates as the situation develops.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Class cancellation was decided after Austin Police, the ATF, and the FBI had begun sweeping buildings with bomb-sniffing dogs
The decision to cancel all classes for the day — rather than reopen later in the morning — was characterized by KUT as exceeding the recommendations of consulting agencies

Classes on the Main university campus are cancelled for the remainder of Friday, September 14, 2012. University buildings may be re-entered effective noon today. All University activities except for scheduled classes will resume at 5:00 pm this date.
Issued at noon, approximately 2 hours and 10 minutes after the evacuation order — a relatively quick re-entry given the scale of the campus
Specifies that 'activities except for scheduled classes' would resume at 5 PM, allowing libraries, gyms, and athletic events to function while academic instruction remained canceled
The careful three-clause structure (classes canceled, buildings reopened, activities resumed) became a template subsequent universities cited in their own bomb-threat response plans
Context

Background

The September 14, 2012, bomb-threat hoax at The University of Texas at Austin was, at the time, one of the largest peacetime evacuations of a U.S. college campus. At 8:35 AM CDT, a male caller with what was described as a Middle Eastern accent told UT operators he was affiliated with al-Qaeda, had placed bombs across the Forty Acres, and that they would detonate in 90 minutes. UT police consulted with the FBI for 75 minutes before issuing the evacuation alert at 9:50 AM CDT — a delay that became the central point of post-incident scrutiny. President Bill Powers told reporters that day, 'We were not confident it was not credible,' a double-negative that captured the institutional caution but did little to satisfy critics. The campus, which enrolled more than 51,000 students, was systematically cleared with the help of Austin Police, ATF, and bomb-sniffing dogs; no explosive devices were found. Almost exactly contemporaneously, North Dakota State University in Fargo evacuated its 20,000-person main and downtown campuses after a similar 9 AM threat — leading the FBI to investigate whether the calls were linked. UT students and faculty re-entered buildings at noon and the all-clear was issued. The incident prompted formal review of UT's emergency notification protocols and is widely cited in campus risk-management literature as a case study in balancing credibility assessment against the imperative for speed.
Analysis

Key Findings

The 75-minute delay between the threat call and the evacuation alert — driven by FBI consultation — became the central post-incident scrutiny point, with critics noting that any actual bomb on a 90-minute fuse would have detonated almost simultaneously with the alert
More than 50,000 students, faculty, and staff were evacuated in a single coordinated effort using UT's mass-notification system, which reached approximately 69,000 mobile users
A near-simultaneous bomb threat targeted North Dakota State University the same morning, prompting FBI coordination across two campuses 1,300 miles apart
The threat was determined to be a hoax with no devices found; the caller was never identified, leaving the case open and contributing to nationwide debates about how universities should evaluate credibility before triggering mass evacuations
Outcome
No bombs were found and the threat was determined to be a hoax. Classes were canceled for the remainder of Friday, September 14, 2012, with buildings reopened at noon and university activities resuming at 5 PM. The 75-minute delay between the threat call and the evacuation alert drew significant scrutiny in subsequent days, with UT President Bill Powers defending the timing as necessary for consultation with federal law enforcement. The case was never solved; the caller was never identified.
