4.1-magnitude earthquake shakes Johor, Malaysia News - AsiaOne

[ysh02]

So near Singapore but why no after quake record leh...

[Ola]

Theirs is 4.1 so by the time come to SG could be 2.2 or so

This magnitude is small and many people will not feel it

Unless animals like horses, roosters . . .

But I agree, SG residents would still like to know

Especially, those living in high floors will feel the shake more

[watchfirst9]

Sg is blessed,
so far very few and very weak.

So near; next time maybe nearer like Kota Tinggi lah....

4.1-magnitude earthquake shakes Johor, Malaysia News - AsiaOne

Next station: Woodlands lah!

[Ola]

Yar hor. If got earthquake, then the High Speed Rail broken into 2?

Or will they use Earthquake Resistant Technology like Japan?

[victortan]

spore will have one, sure kana jiat lat one.

Woodlands Causeway and Tuas 2nd link will also be gone liao lah!

[Huliwang]

Better dun go JB for time being until a complete assessment of the earthquake and tectonic plates there are made. Dun suay suay you get caught in a 8 magnitude quake while you are shopping shiok shiok there.

Woodlands Causeway and Tuas 2nd link will also be gone liao lah!

Woww...how if quake come...

Must find somewhere to hide lah!

‘I thought house was about to collapse’: Mild earthquake strikes Segamat in Johor

A minor 4.1-magnitude earthquake that occurred few days morning a in Johor – with its epicenter about 130 kilometer north of Sedenak which is home to most international data centers in Malaysia, has shaken up some in the industry. Long thought of as free from major earthquakes that can cause damage, Malaysia now faces the prospect of having to deal seriously with earthquake preparedness, something that few in the country have expertise in. Seismic researchers have hypothesized that strong earthquakes in Indonesia could have reactivated ancient fault lines causing a sudden rise of earthquakes in Peninsular Malaysia since the 2000s. 

Forty of the 59 earthquakes in the peninsular (or known as West Malaysia) have occurred between 2007 to 2020 following two powerful quakes in Indonesia. But these are all weak quakes registering less than 4.0 on the Richter scale and did not cause any serious property damage or casualties. Anything above 6.0 could cause some serious damage...In fact, there is already a fault line known as the Kuala Lumpur Fault (KLF) that stretches across Kuala Lumpur and Selangor from the Pahang-Selangor border in addition to the Bukit Tinggi Fault (BTF). These two, KLF and BTF are the two most active faults in West Malaysia, among several less active ones that have been identified in recent years.

But since the Segamat quake, which was followed by a 2.8 magnitude aftershock four hours later in Yong Peng (also in Johor state), experts such as UTM senior lecturer Dr Mohd Zamri Ramli, had reportedly suggested the presence of a new fault in Johor in addition to the known Mersing fault. However, MetMalaysia has indicated that the two recent quakes had occurred within the Mersing Fault Zone.

Since then, a third earthquake had struck 18km south of Segamat around 9am three days after the first quake hit. Tremors from the 3.2-magnitude quake were felt in most areas of Johor and Southern Pahang, according to MetMalaysia in its Facebook page on Wednesday. The suggestion that there is a new fault in Johor is beginning to hold credence.

According to experts, there are several fault lines and fault zones in Malaysia that have the potential to become the epicentres for minor earthquakes – a worrying fact indeed considering Kuala Lumpur and Selangor house a number of international data centers not to mention the highest population density in Malaysia. Johor meanwhile especially the Kulai area has the most number of data centers in Malaysia.

There is a silver lightning however – according to experts, the probability of an earthquake recurring within the same location is about 475 years! Well, that’s cold comfort indeed for fault lines that have never made their maiden debut. The uncomfortable truth is experts have warned that there is a possibility of an earthquake above 5.0 on the Richter scale occurring in West Malaysia; the exact timing and location of which are unknown of course.

But it’s not like M'sia does not have building laws mandate earthquake resistance measures. It has made into law the National Annex to Eurocode 8 (EC8), officially known as MS EN 1998-1:2015 which is the construction standard for seismic resistance for building structures. Under the EC8 standard, the building must be able to withstand seismic movements. To do that, engineers must first conduct structural modelling and analysis during the design process. And such detailed structural plans must be submitted to the local council before the start of construction, an engineer reportedly told a local paper.

But here’s the catch – local authorities are given the autonomy whether they wish to implement this standard, whether in whole or in part, or not at all. This is because all land matters are a prerogative of each individual state in Malaysia. Hence, even though the Uniform Building By-laws (UBBL) which adopted the EC8 standard, has been gazetted by the Federal Government and comes into effect in 2022, it does not mean all data centers in Malaysia built after 2021 have incorporated seismic resistance into their buildings. It would depend on whether their local authority has mandated it by formally gazetting the seismic provisions into their local building by-laws. M'sia’s Street, Drainage and Building Act 1974 (Act 133) allows each state (except Sabah and Sarawak) to gazette, adopt any amendments to the UBBL before they can be implemented in their state. For existing buildings, owners can choose whether to comply with code or not. They either upgrade or retrofit their building if they choose to.
Data centers, being mission critical
buildings, if they haven’t yet adopted earthquake resistance measures should undertake seismic vulnerability studies and if necessary, retrofit or strengthen their structural performance, according to the engineer. For buildings that have not started construction, it might cost up to 15% total building costs if earthquake-resistant features are incorporated, experts estimate.

In the case of Johor, a search did not reveal any such gazette in publicly accessible record. Hence, unless there is internal unpublished directive, situation is uncertain. w.media has reached out to the relevant people and replies are still pending at the time of publication. This is a developing story will be updated accordingly when new information emerges.

SINGAPORE – A mild earthquake with a magnitude of 3.2 struck Johor on the morning of Aug 27, with tremors felt in parts of the southern Malaysian state and southern Pahang. The Malaysian Meteorological Dept (MetMalaysia) said in a Facebook post that the earthquake was recorded 18km south of Segamat at 8.59am. The epicentre was located at 2.33 deg north and 102.79 deg east, with a depth of 10km

KUALA LUMPUR – 1/2 hour before dawn, Segamat resident Yvonne Liu was jolted awake by a thunderous bang that lasted several seconds. Outside her window, dogs were barking loudly & anxiously. “I felt earth shake, like a  dinosaur had passed by my house,” the 52-year-old housewife told The Straits Times on Aug 24 about the 4.1-magnitude earthquake that left her & neighbours unnerved.
