Minor earthquake rattles Lamphun, Chiang Mai with no damage
An earthquake measuring 2.5 on the Richter scale struck Lamphun, with tremors felt in two districts across two provinces. Occurring at a shallow depth of 1 kilometre, this seismic activity was triggered by the Mae Tha fault line. Residents reported no damage.
The Department of Mineral Resources, under the Ministry of Natural Resources and Environment, issued a warning regarding the minor earthquake that took place yesterday, November 21 at 8.45pm. The epicentre was pinpointed in Ban Thi, Lamphun.
Categorised as a micro-earthquake due to its small magnitude, the event was caused by the shifting of the Mae Tha fault line, which runs in a northeast-southwest direction and exhibits a left-lateral strike-slip fault movement.
“The earthquake was minor, and no significant damage has been reported,” stated a representative from the Department of Mineral Resources. “We are monitoring the situation closely and will provide updates if more information becomes available.”
Residents from Ban Thi in Lamphun, as well as those from On Tai in San Kamphaeng and Nong Phueng in Saraphi, Chiang Mai, reported feeling the tremors. Despite the widespread awareness of the quake, initial assessments revealed no structural damage or injuries, providing relief to the local communities.
The Mae Tha fault line, known to influence seismic activity in the region, has been under observation due to its potential to cause minor earthquakes. Such geological features are typical in areas with tectonic movements, although they rarely result in significant damage when the magnitude is low. The recent event serves as a reminder of the importance of understanding and monitoring these natural occurrences to mitigate risks and ensure public safety.
Seismologists and relevant authorities remain vigilant, keeping a close eye on any further movements along the fault line that could pose a threat. Preparedness and awareness among the residents play a crucial role in minimising potential impacts from future seismic activities.
While the recent earthquake did not lead to any immediate harm, officials advised residents to stay informed and prepared for any future incidents. The Department of Mineral Resources continues to monitor the situation, ensuring that any new developments are communicated promptly to the public, reported KhaoSod.
Frequently Asked Questions
Here are some common questions asked about this news.
Why is the Mae Tha fault line significant in understanding regional seismic activity?
It’s a key geological feature influencing local earthquakes, crucial for monitoring potential seismic risks.
How does the left-lateral strike-slip movement of a fault line affect seismic activity?
It causes horizontal shifts, potentially triggering earthquakes by releasing built-up tectonic stress.
What if a larger earthquake occurred along the Mae Tha fault line?
A greater magnitude could lead to significant damage, highlighting the need for effective preparedness.
How do micro-earthquakes serve as indicators for future seismic events?
They reveal underlying tectonic stress and fault line activity, aiding in risk assessment and monitoring.
What role does public awareness play in earthquake preparedness?
It minimises impact by ensuring communities are informed and ready for potential seismic events.
