Residents discovered four separate fires at around 1 pm on June 7 in a coastal forest area in Ninh Chau Commune, near the site of a previous wildfire on May 26.
The affected forest is managed by the Dong Hoi and Coastal Protection Forest Management Board.
Hot, dry conditions and strong southwesterly winds allowed the fires to spread rapidly through dense, dry vegetation, complicating firefighting efforts.
Local authorities quickly mobilised emergency responders and requested support from specialised firefighting units. More than 300 personnel, including police officers, forest rangers, border guards, militia members and local residents, were deployed to contain the blaze.
Provincial leaders and relevant agencies also travelled to the site to oversee firefighting operations.
Authorities instructed emergency services to strengthen coordination, establish firebreaks and prevent the flames from spreading to nearby forests and residential areas.
By late June 7, the fires had largely been brought under control, although crews remained on site to extinguish smouldering hotspots and monitor the area for possible flare-ups.
Local authorities said personnel would continue patrolling affected areas as high temp
