Thailand at Risk of More Unpredictable Earthquakes, Experts Warn

At a recent seminar, academics highlighted Thailand's ongoing vulnerability to earthquakes, emphasising the unpredictability of when and where they might occur. This discussion took place during the 32nd "Chula the Impact" seminar at Chulalongkorn University.

 

Santi Pailoplee, a noted geology professor, explained that while scientists can identify areas at risk, predicting exact times and places remains impossible, dismissing any premature warnings as fake news. Aftershocks typically decrease in strength, but their occurrence is directly linked to the magnitude of the initial quake, he noted. An example cited was Indonesia's devastating earthquake, which resulted in approximately 500 aftershocks.

 

Notably, aftershocks from last Friday's quake no longer threaten Thailand, Santi reassured. However, Panya Jarusiri, another geology expert, pointed to the active Sagaing Fault and Thailand's 16 active fault lines as ongoing concerns. Risks from undetected faults like those in Phitsanulok and Kanchanaburi warrant caution, he added.

 

 

 

On building safety, civil engineering lecturer Chatpan Chintanapakdee recognised improvements in construction standards post-2007 but called for stringent inspections to ensure new buildings are designed to be earthquake-resistant. Furthermore, Angkanawadee Pinkaeo, a law academic, stressed reviewing insurance policies to ensure comprehensive coverage and address liability issues, particularly in light of the new State Audit Office building collapse.

 

With these discussions, experts aim to better prepare Thailand for future seismic events, combining research insights with construction safety measures, reported Bangkok Post.

Yes, that will restore faith in the 'high-rise' market

Genius. My guess is somewhere near or around fault lines and earthquakes by their very nature are unpredictable about location and time. I'm no "expert" though.

That is about the stupidest statement I have ever heard.  "Expert?"  The essence of earthquakes IS their unpredictability. 

"Earthquakes are unpredictable.  I'm an expert.  I know!"
🙅‍♂️ "I'm a 4 year old and mummy has told me the earthquakes are unpredictable."

I'm Captain Obvious and I'm here to tell you that Earthquakes Are Unpredictable! See - I'm an "expert" too! 

"Experts."  <gag> 

[connda]

The main-stream media and "experts" will milk this for Maximum Fear. 

"Expert say that if you wear a mask 24/7 you are 23.3845% less likely to experience an earthquake." 🙄

Construction standards are only as good as the corruption which bypasses the standards.

Knowing everything, what can anyone do to solve the problem? Fill in the fault lines with concrete? Even upgrading the construction of high rises is pointless if engineers take bribes to "help" rich owners escape stringent tests.

I only read the headline, then thought, why read the rest, I'm not an expert, but I do know, no-one can predict earthquakes

Do you know what a fault line is...555

[CanadaSam]

Earthquakes relieve stress along fault lines. 

 

After stress is relieved, it takes decades to build up again.

 

Anyone saying there is going to be another earthquake soon, is not an expert, he is an idiot.

[Rolo89]

There could be a strong earthquake that levels most of BKK tomorrow with it being built on jelly. Or it could be in 300 years. No one knows.

[bluemoon58]

And you're saying this now! Any chance you can pre-warn in the future instead of after the event?

The headline is completely misleading & alarmists.

 

The article itself, accurate & factual and paints a very different picture than the headline implies. 
 

Facts: Minor aftershocks & tremors will occur & typically decrease in strength.

 

Other faults exist but are not major on plate boundaries & present low intensity ‘seismic risk’.

Correct, however the article also says that.  It’s just the headline that’s somewhat alarmist.

No there cannot.

 

This is about as strong as the Local magnitude (ML) in Bangkok could get as it sits too far away from any major plate boundary. 
 

Soft sediment / basin amplification was a major factor in the Magnitude experienced in Bkk, nevertheless this was as high as it gets (reasons explained in other threads I can link to later) 
 

The Sagaing fault hit hits highest ever magnitude - previous to that was in 1912 when 7.9 Mw was recorded.

Fair guess. Regional location is broadly predictable but timing, so far, not so.

The only real mitigation here would be the second of your suggestions. The fact that taller but better constructed towers survived well shows that success is possible, but only with high-level construction expertise, architecture, technique, workmanship and materials.

The epicenter of this quake was 10km deep on at 1200 km fault line….    

 

Fill it with concrete ? Seriously..,

 

There’s a fundamental flaw in your understanding of tectonics, plate boundaries & faults….   There’s nothing to be filled. This strike slip fault is shear - no gaps - just two masses of land sliding / trying to slide past each other (layman’s terms)….

 

… But, even without that understanding… filling one bucket of cement at 10km depth is rather impossible (due to geothermal gradient alone).

What if there is already high stress in an adjacent fault? Or even closer to Yangon and Bangkok along the same fault?

Experts... it is April so we should expect hot air

No.

 

There can be a closer, longer and stronger earthquake hit BKK. If this is during monsoon could be really really bad for BKK. The other day was just a taster.
