In Thailand, the memory of devastating tsunami of 2004, which cost the lives of more than 5,000 people, remains alive. In order to prevent future tragedies, the country has put in place new detection devices in order to strengthen its alert system. These technological innovations aim to ensure increased vigilance in the face of seismic risks and to minimize human losses during possible maritime cataclysms. Through the installation of sophisticated detection buoys and the networking of alert towers, Thailand aspires to guarantee effective protection for its coastal populations.
Since the tragedy of December 26, 2004, during which a tsunami caused the death of more than 5,000 people in Thailand, the country has become aware of the importance of an effective warning system. The implementation of new tsunami detection devices aims to improve the safety of coastal populations and limit human losses in future disasters. These technological advances, based on an international network, make it possible to detect tsunamis and quickly alert the authorities and the population.
Global Warning and Detection System
Following the 2004 disaster, governments around the world worked together to establish a global tsunami information system. The program, known as Deep-Ocean Assessment and Reporting of Tsunami (DART), is based on a network of detection buoys scattered around the world, of which 74 buoys are currently operating. These buoys, which float on the surface of the water and are connected to sensors placed on the seabed, are able to measure changes in water level and signal the occurrence of small earthquakes that can lead to tsunamis.
DART buoys in Thailand
In Thailand, two DART buoys have been established, providing essential coverage for tsunami detection. They are connected to 130 control towers spread across six coastal provinces. Each tower is equipped with sirens and loudspeakers broadcasting warnings in five languages. These facilities allow for a significantly reduced warning time, with notifications received within5 to 7 minutes of a detection. The role of modern technologies
Advances in communication and detection technologies have transformed the way warnings are transmitted. Before 2004, it could take
15 to 50 minutes to issue a warning, but today, the DART system and modern control towers ensure a much faster response. Although cell phones and alert apps have become popular tools, the role of control towers remains essential, as many coastal residents indicate. Challenges to overcome
Despite these advances, certain challenges remain. For example, detection buoys need to be replaced regularly, and it is crucial that the system is properly maintained to ensure its effectiveness. Indeed, it has been observed that in other regions such as Sri Lanka, a large number of alert towers continue their operations but with communications equipment that has become obsolete. To address these shortcomings, local companies have formed
key contact networks to quickly transmit alerts in coastal areas. Raising public awareness
Public awareness also plays a crucial role in tsunami safety. The memory of the 2004 disaster remains alive among residents. Community leaders, such as village chiefs, are encouraging residents to remain vigilant and follow evacuation protocols, even during false alarms. Confidence in the current alert system appears to have grown over the years, despite occasional incidents of inappropriate alerting.
As Thailand continues to establish and strengthen its tsunami detection systems, the international community remains engaged in this fight against natural disasters. Recent discussions highlight the importance of continued vigilance, as there is always a risk that events similar to those of 2004 could occur again. When it comes to disaster preparedness, the combination of advanced technologies, reliable warning systems and community engagement is proving to be the key to minimizing the impacts of tsunamis in the future.

Q: What tragic event led to the improvement of tsunami detection systems in Thailand?
A: On December 26, 2004, a 9.1 magnitude earthquake triggered a tsunami that killed more than 5,000 people in Thailand, prompting authorities to improve warning systems.
Q: What are the main tsunami detection systems in place in Thailand?
A: Thailand has two DART buoys linked by satellite to 130 control towers in six coastal provinces, enabling early warning.
Q: How quickly are alerts being issued today compared to 2004?
A: Today, alerts can be broadcast in 5 to 7 minutes, unlike the 15 to 50 minutes that could pass before 2004.
Q: What is the role of DART buoys in the warning system?
A: DART buoys float on the ocean surface and detect seismic signals as well as changes in water level, allowing continuous monitoring of tsunamis.
Q: How do local authorities contribute to the safety of coastal communities?
A: Local residents, such as village leaders, actively participate in evacuations during alerts, even those considered false alarms.
Q: What difficulties do other countries like Sri Lanka face with their warning systems?
A: In Sri Lanka, a large number of alert towers are no longer operational due to obsolescence of communications equipment.
Q: What is the experts’ perspective on the possibility of future tsunamis?
A: Experts stress that there is a “100% chance” that another tsunami of the same magnitude as that of 2004 will occur in the future.
