Bangkok: Disaster experts have issued a warning about potential aftershocks in Thailand, anticipated to occur within the next 2-3 months. These aftershocks are expected to decrease in intensity, but residents are advised to live with understanding and take steps to mitigate the impact.
According to Thai News Agency, Assoc. Prof. Dr. Seri Supratid, a disaster engineer, disclosed that the recent earthquake might be the most severe in nearly a century, drawing comparisons to the 1930 earthquake in Myanmar with a magnitude of 7.5. Asst. Prof. Seri explained that the earthquake resulted from the movement of the earth's crust. However, there is no clear evidence linking it to climate change. While the exact number of aftershocks cannot be predicted, historical data suggests there could be 700-1,000 aftershocks following such a strong quake.
The initial earthquake in Myanmar was followed by a significant aftershock with a magnitude of 6.4 just 12 minutes later. Although the magnitude of future aftershocks is expected to be smaller than the initial 7.7 magnitude earthquake, attention should be focused on potential mainshocks in other areas. Myanmar remains a high-risk zone due to the presence of the Sagaing Fault, and aftershocks are expected to continue over the next few months.
In Thailand, current building regulations allow for accelerations of 0.08-0.14, but the recent earthquake saw an acceleration of 0.24. In Chiang Mai, accelerations were recorded at 0.05 G, diminishing further in Bangkok. Concerns arise from Bangkok's soft soil composition, affecting older structures. Buildings constructed in the past decade, compliant with recent regulations, are considered relatively safe. However, incomplete or under-construction buildings may be at risk.
Residents in Bangkok and across Thailand are advised to remain vigilant. While the intensity of aftershocks is expected to decline, it is crucial for people to be educated on earthquake safety measures, such as seeking shelter under sturdy furniture or moving to open spaces when tremors occur.
