A South Carolina festival stampede left at least 19 people injured early Sunday after panic spread through a crowd during a major biker event in Atlantic Beach.
Emergency crews responded shortly after 1 a.m. near a stage area along South Ocean Boulevard during the Black Pearl Cultural Heritage and Bike Festival. Officials said the incident caused chaos for several seconds as people suddenly began running through the crowd.
Horry County Fire Rescue confirmed that 19 people were evaluated for injuries following the crowd surge. Three injured people were taken to the hospital for treatment, while other attendees may have transported themselves to nearby medical centers.
Authorities said none of the injuries appeared to be life-threatening.
Because of the number of injured people, emergency officials declared a mass casualty incident. This type of declaration helps emergency teams organize medical care and response efforts when several people are hurt at the same time.
According to Atlantic Beach officials, the South Carolina festival stampede started when one person began running near the crowded stage area. That movement reportedly caused fear and confusion among nearby attendees, leading to a chain reaction inside the crowd.
Town officials said the panic lasted only a few seconds before law enforcement and emergency crews regained control of the area.
Authorities stressed that there were no confirmed fights, shootings, weapons, or direct threats to public safety connected to the incident.
Officials said police officers and emergency teams were already positioned across the festival grounds at the time of the crowd surge. Responders quickly moved into the area to help injured attendees and calm the situation.
Medical crews treated several people at the scene before normal festival operations resumed later in the night.
Atlantic Beach officials released a statement expressing concern for those affected during the incident. Leaders said any situation involving injuries is taken seriously and remains a priority for public safety teams.
The town also said the isolated moment should not overshadow the overall success and long history of the festival.
The Black Pearl Cultural Heritage and Bike Festival is one of the largest motorcycle rallies held during Memorial Day weekend in the United States. The event has taken place for more than 40 years and attracts visitors from across the country.
Officials estimate that hundreds of thousands of people travel to the Myrtle Beach and Atlantic Beach area during the holiday weekend for concerts, motorcycle events, parties, and entertainment activities.
Large crowds are common throughout the weekend, especially during nighttime concerts and stage events.
Town officials said several crowd-control measures had already been put in place before the incident happened. Authorities temporarily stopped incoming traffic into Atlantic Beach on Friday night and again on Saturday evening to manage congestion and improve public safety.
Festival organizers and emergency officials said they will continue reviewing the crowd surge incident to identify possible safety improvements for future events.
Crowd surges and stampede situations can happen quickly in large gatherings when panic spreads through tightly packed groups of people. Safety experts say even small moments of confusion can trigger dangerous reactions if crowds believe there is a threat nearby.
Officials often encourage event organizers to improve communication systems, crowd spacing, emergency exits, and on-site security to reduce risks during major public events.
Despite the late-night panic, authorities said emergency teams responded rapidly and helped prevent more serious injuries.
The South Carolina festival stampede has renewed attention on crowd safety at large entertainment gatherings across the United States, especially during busy holiday weekends that draw massive numbers of visitors.
Atlantic Beach leaders said they remain committed to working with public safety partners to maintain a safe environment for future events while preserving the long-running festival tradition.
Authorities have not released additional updates about the injured attendees or whether any further investigation will take place.
