bo pian la...

natural disaster / want to come will come one la / MYBFA....

Maybe it is time to ensure our infrastructure can survive stronger earthquake

Knn
Bto finish built already find out so many cracks or issues
You reckon will tahan the strong quakes?

This picture has been going around internet.

The two earth quake yesterday are all in the light brown belt.

Earth quake knows no international boundary. So chance of at least the western half of Singapore getting it, is have one.

Help you all draw line.

Probably something like this.

That coincides with the Nee Soon fault.

Still talking about 24th aug johor quake

Is Sinkie land ready for earthquakes
Mine understanding is that HDB build in the 70s cannot stand eartgquakes at all
The latest 1 can only withstand abit

 

[coyote]

If JH public infrastructure survived 4.1 earthquake… then sinkie ones should be safer…

There are little high rise buildings around that area...

Singapore has much more help high rise buildings.

Does anyone knows why the NEA app , myenv, did not report of this Malaysian earthquake? They kept on alerting earthquake in indo, Philippines, Japan and even Russia but got nothing on the Malaysia quake till now...


Read HWZ Forum Rules!

magnitude too small?

After earthquake will have sinkholes

Wa really is
East Side Best Side
West Side Backside!

Here is a more detailed pic from the researchgate document. Courtesy of our own DSTA.
East side is mostly old alluvial deposits. West side, save for the reclaimed area is mostly bedrock.

Beside public infrastructure… building safety for private homes falls on the building owner Tio Bo???
Those sexpensive ATAS Private condo and Landed house? No more warranty Liao… Good luck to them….

Then the situation should be better for West right. Since the houses there are built on solid rock, while the houses in the East are built on shifting sand.

It's actually not so simple. Now I am talking out of my arse here so the terminology may be wrong. The concept though is there.

1. Solid rock transmits vibration very well to the foundations of buildings. Buildings piled into solid rock will be exposed to hard shaking more directly since there is no dampening. There is no rubber between the moving floor and say a tall bookshelf. The smallest movement will cause the whole bookshelf to directly experience the full magnitude of movement.

2. Soft deposits - Buildings built here experience this "rubber" dampening effect. The buildings won't shake as hard - but the land itself will shake more and harder as time goes by due to induced resonant frequencies. Its like gently hammering on a railing. It starts vibrating a little, but as time goes by it really starts shaking. This effect is magnified in softer ground.

I expect there might be emergency inspections needed for structures. Warranty? There really isn't such a thing. There is insurance though. Earthquake damage should be covered. Bear in mind this is not an active earthquake zone. If it were, there'd be exclusions written into the policy. Same concept for flood and wildfire areas.

You know in some places a special additional wildfire coverage needs to be purchased? And the insurance companies always set it up to expire just before wildfire season. If you forget to renew, GG if a fire claims your neighbourhood.

Many home insurances cover only up to a few thousand K(renovation only)….Rich sinkies and family worth much more than this….many of them are multi millionaires

First time I think heard jb got earthquake.

In HDB, cost of gross structural repairs and replacement will be born by HDB. Homeowners only need worry about cosmetic rectifications IMO. (this is the fire insurance) Content coverage is additional.

In Condos and maybe strata landed, the MCST will play the role of the HDB. Whether or not they actually have adequate coverage is another thing. Here the homeowner's fire insurance coverage is for localized in-unit damage just like HDB. Content coverage is additional.

For private landed, the homeowner bears everything. There is reconstruction coverage for the bare structure, which is roughly equivalent to fire insurance in a flat or condo. Content coverage is additional.

Johor not THAT many high rise and no need to pack so closely to each other
but SG, u see the new towns
one fall the rest domino liao isn't it?

Las time my Japanese friend keep emphasis that reclaimed land will melt when earthquake happen upoon learning that some of our cbd on reclaimed la d

Based on the Mexico City - Acapulco earthquake, the buildings on loose soil material suffered more damage.
https://en.m.wikipedia.org/wiki/1985_Mexico_City_earthquake

"Coastal and most inland damage was moderated by the fact that most of the west of Mexico sits on bedrock, which serves to transmit the shockwaves without amplifying them. La Villita, and Infiernillo Dams, near the coast, were superficially damaged and undamaged respectively."

And much closer to home in time and space was the Myanmar earthquake. Bangkok being built on loose river soil suffered significant damage despite being hundreds of km away from the epicentre.
