Singapore is 100% blessed against Earthquake and Volcanoes de woh, Boss John true?

One volcano of concern is called KW-23612, currently in deep slumber in the northern South China Sea. One battle scar it has is a 7km-wide crater-like depression, or caldera, at its centre. This is a sign of an explosive, catastrophic eruption in the past, which caused the volcano to collapse and expel magma forcefully.
The caldera is nearly twice as wide as that of the Tonga volcano and Mount Pinatubo, both of which are about 4km wide, noted Dr Verolino, who is part of EOS’ coastal hazard group.
“For a volcano to grow that big and have such a hole in the middle means there was intense explosive activity,” he added. The caldera’s summit is also considered shallow, just 200m below the sea surface.
“Eruptions from such a large volcano may cause powerful tsunami waves spreading all over the South China Sea, including areas of the Sunda Shelf, potentially affecting countries farther away, such as Malaysia and Singapore. These are rare events and there is no such record for Singapore, but this is a topic we are doing active research on,” said Dr Verolino.

These are rare events and there is no such record for Singapore, but this is a topic we are doing active research on,” said Dr Verolino.
The NTU investigations were published in the scientific journal Natural Hazards And Earth System Sciences in April.
A key purpose of mapping and classifying how hazardous the seamounts can be is to identify places at risk if any understudied volcano were to erupt. The researchers found that Taiwan is most at risk, followed by Indonesia, the Philippines and Vietnam.
This finding was based on the populations of these places, the amount of submarine cables nearby and ship traffic.
For Taiwan, there are three hazardous volcanoes located up to 60km north-east of highly populated Taipei.
More than 2,500km of subsea cables are exposed to Taiwanese volcanoes, which means that lava flows or submerged ash and rocks can damage the dense cables north and south of Taiwan, said the paper.
Taiwan’s ship traffic also appears to be the densest in the entire region studied, and floating volcanic rocks can disrupt navigation.

Dr Verolino said: “Underwater volcanoes are often overlooked because they were not thought of as an imminent threat. But as the Tonga eruption showed, we saw the potential of these kinds of volcanoes. We need to assess and create different scenarios to see the possible effects.”
In ongoing research, Dr Verolino has done simulations to show how mega eruptions by KW-23612, for example, can lead to far-reaching tsunamis across South-east Asia.
Tsunamis of such scale are known as meteotsunamis, caused by shock waves or atmospheric disturbances.
This was last seen after the Tonga explosion, when air moved away from the volcano fast. This big movement of air pushed water away, setting off the far-reaching tsunamis.
Dr Verolino’s simulations showed that tsunami waves of a few centimetres can reach Singapore’s south or south-east coast, but the study has not yet been published and the results are being validated.
“Even centimetric tsunami waves can form strong currents near Singapore, affecting boat traffic, beach localities, and can lead to coastal flooding... For tsunamis coming from the South China Sea, the east will be first exposed, where Changi is,” he noted.
Beyond tsunami waves, threats to Singapore’s connectivity is another risk if subsea cables are damaged by volcanic activity.
Ms Nadya Melic, vice-president for product at GCX that invests in building subsea cables, said: “While Singapore is deemed a more protected location... any fault affecting an end-to-end cable segment could also affect connectivity on a certain segment of a cable that is directly linked into Singapore... Traffic can be redirected onto another system.”
Beyond threats from the South China Sea, Dr Verolino noted that little is known about the undersea features of the Sunda Shelf, a continental extension on which sit Bali, Borneo, Java and Sumatra. Satellite data cannot tell much, and no eruptions were recorded.
“If there are other volcanoes in this area, which is closer to Singapore, we don’t know yet,” he said.
Dr Verolino is hoping that his research on the more than 460 volcanoes will spur more deep-sea exploration into these enigmatic seamounts.
“We wanted to help narrow down the search of notable volcanoes before an eruption. Identify a few volcanoes of interest to propose projects for funding and exploration.”

This kind of fake news which pretty much a fictional news. Does it look like a science to you?
Yeah...there is no volcano under the sea...hehehe
It is all fake science...for your entertainment only
Who still believes in fake stream media these days are really low in IQ
If sheeple still fall for such fake news, the joke is on them, not the fake stream media

Never say never. One single 5.0 Richter hit will collapse all HDB.
No need Putin to nuke and KeeChiu will have his "Singapore will not last 100 years" prophecy come true.

No need to believe...just have a listening ear
See what is next on wayang list
Will be very interesting
Once you know that your belief is aligned to the majority, then you will know you are just part of the sheeple population.

Dun say that....70% believe they are in good hands.
I am sure more will be agreed very soon
