Me too, must be another Meteorology department blunder. I felt the 2 about 6 years ago nothing since ; " Rattled" was the description, LOL.

Magnitude 5 earthquake may hit Chiang Mai and Chiang Rai in next 10 years

Great journalism, we already had a 6.0 and a 6.7 in the last 10 years.

There have been no reports of damaged buildings, roads, dams or casualties.

 

 

Bit difficult to damage the road.  You could bomb the 118 and no one would notice the difference.

I never knew earthquakes made a sound,

 

I've lived through three major quakes. Two in California, and one in Japan. Close enough in all three to have everything knocked off my shelves in the kitchen and all my bookshelves, and structural damage to my house in Japan. As is normal in Japan, all our large, tall furniture (amoires. dressers, sideboards, TV, etc.,) was bolted to the walls so didn't fall over on us, but the quakes shook us out of bed and scared the living daylights out of us!

Two of the quakes sounded like freight trains coming through my living room. The third was absolutely silent.

 

I don't like earthquakes

 

I went through well, i guess tens of earthquakes (part of my job) and they make noise, but the further you are from the epicentre, the more it will be in the infrasound range (like a heavy truck on a road nearby...) or even lower. P-waves can be in the 30-40Hz range and transferred to the air; S-waves are silent but can be felt.

 

Closer to the epicentre, it is often in the audible range for humans as higher pitch waves haven't been absorbed to heavily yet.

 

That's of course independent of any human-related noise (furnitures, buildings, cars, not so rigid materials, etc.). So I'm just talking about the sound it makes in the middle of dry flat field.
