Earthquake rocks Thailand / Myanmar

Thailand are Myanmar are not even within the Pacific ring of fire. So if they can kena, so can Singapore and Malaysia. Very scary!:eek:

The primary countries that fall within the Ring of Fire are:

1. Indonesia
2. New Zealand
3. Papua New Guinea
4. Philippines
5. Japan
6. United States
(specifically, the states along the Pacific coast and Alaska)
7. Chile
8. Canada
(primarily British Columbia and Yukon)
9. Guatemala
10. Russia
(eastern regions, particularly Kamchatka Peninsula)
11. Peru
12. Solomon Islands
13. Mexico
14. Antarctica
(parts of the Antarctic Peninsula)

The ring of fire refers to VOLCANIC activity.

Earthquakes on the other hand occur along fault lines where separate tectonic plates meet. When a slip occurs along these stress points the result is an earthquake.

The Sagaing Fault line runs through Myanmar with the India plate on one side and the Eurasia plate on the other which is why the area is earthquake prone.

I believe it refers to both. But you are right, only 90% not 100% of earthquakes occur within this ring of fire.

Ring of Fire​

The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) is a tectonic belt of volcanoes and earthquakes.

It is about 40,000 km (25,000 mi) long and up to about 500 km (310 mi) wide, and surrounds most of the Pacific Ocean.

The Ring of Fire contains between 750 and 915 active or dormant volcanoes, around two-thirds of the world total. The exact number of volcanoes within the Ring of Fire depends on which regions are included.

About 90% of the world's earthquakes, including most of its largest, occur within the belt.

I guess you can have earthquake prone areas without volcanic activity if there are no fissures that extend to the molten rock layers.

I asked Grok and this is what came up.




Some fault line junctions cause earthquakes without volcanic activity because not all tectonic interactions generate the conditions necessary for magma formation and volcanism. Earthquakes occur whenever there’s a sudden release of built-up stress along faults, regardless of whether volcanic processes are involved. The absence of volcanism at certain junctions depends on the type of fault, the nature of plate movement, and the local geological environment.

Faults come in three main types: strike-slip, normal, and reverse (or thrust). Earthquakes happen at all of them when stress exceeds the strength of the rocks, causing them to slip. However, volcanism is most commonly tied to subduction zones or rifting areas where magma can form and reach the surface. At strike-slip faults, like the San Andreas Fault in California or parts of the Sagaing Fault in Myanmar, plates slide past each other horizontally. This lateral movement generates friction and stress, triggering earthquakes, but it doesn’t typically involve the melting of rock into magma because there’s no significant subduction or thinning of the crust to allow magma to rise.

Even at plate junctions, the outcome depends on the dynamics. Take a transform boundary—where plates grind sideways, like the boundary between the Pacific Plate and North American Plate along the San Andreas. Earthquakes are frequent due to the locked sections of the fault slipping, but there’s no subduction to drive melting, and the crust isn’t being pulled apart to expose the mantle. Contrast this with a subduction zone like the Cascadia Subduction Zone, where the Juan de Fuca Plate sinks beneath North America, causing both earthquakes (from the plate interface) and volcanism (from magma generated by the subducting slab).

At triple junctions—where three plates meet—whether volcanism occurs depends on the configuration. The Mendocino Triple Junction off Northern California, where the Pacific, North American, and Gorda plates converge, produces earthquakes because of complex faulting, including transform and thrust movements. But volcanism isn’t prominent there because the dominant motion is lateral or compressive, not extensional or deeply subductive enough to generate significant magma nearby (though the broader region ties into the volcanic Cascades further inland).

The key factor is magma generation. Subduction zones melt the descending plate due to water release lowering the melting point of the mantle, while rifting (like the East African Rift) thins the crust, letting mantle material decompress and melt. At junctions or faults without these processes—say, where plates are just scraping by or compressing without sinking—stress builds and releases as earthquakes, but the heat and material flow needed for volcanism don’t materialize.

So, in short, earthquakes without volcanic activity happen at fault junctions where tectonic movement builds stress but doesn’t create pathways for magma. It’s all about the mechanics of the plates and what they’re doing underground—sliding, not melting.

Heng ah, so SG is safe. We will not be destroyed by shifting plates in the next few millions of years.
 
in sg i would love to. plus a cannon to blast any ah beng car parked in the wrong spot, especially along a solid white line in a narrow street.
But.,,, but I thought you always claim to live in San Francisco or at least in America? Since when you have returned to Singapore?

i share a hdb room in bedok near the hawker center where lau unkers and aunties would hangout and pass their time. i would walk to siglap and imagine i live in a landed home there. there are maids who wake up early to wash their masters’ cars everyday, even when it rains. and once in a while i would meet nigger beng in sf complaining about getting a parking ticket.

Bangkok and whole of Thailand also not in the line of the plates but kanna until very jialat leh. what is there to be heng about? tremor do not care about locations.

i am waiting for channler to talk about this soon. i suspect is the energy cleanse of our negative actions and behaviours.

I think we are quite far away from the nearest fault line which is the Great Sumatran Fault. We might feel very slight tremors which we have in the past.
 
how far is far? bkk is more than 1000km away from the earthquake main site. Is that far?
Oh dearie me! SG is only 400km away from the great sumatran fault. I searched and found this 2014 study. Very long and complex, too cheem for me to understand. But I fished out the conclusion.

SEISMIC LOSS ESTIMATE OF SINGAPORE UNDER A DETERMINISTICSUMATRAN EARTHQUAKE SCENARIO

Under the deterministic M w 7.7 earthquake scenario, the majority of buildings (more than 99%) in Singapore would experience none or slight damage, and a very limited number of buildings would suffer moderate or extensive damage. Although only a small percentage of buildings are exposed to moderate damage state, the estimated total structural loss is about 0.6% of Singapore GDP in 2014. It has been observed that the buildings in the southeast part of Singapore are susceptible to economic losses subjected to seismic shakings. The results demonstrate the potentially high seismic losses of Singapore when large and infrequent distant
Sumatran earthquakes occur.

This method is applicable for cities where seismic site effect is significant. It can be regarded as an alternative method, which might hopefully provide new insights into seismic risk evaluation or loss estimates of urban regions.

Myanmar hit by fresh 5.1 aftershock, tremors felt in neighbouring countries​

KUALA LUMPUR: Myanmar was hit by a 5.1-magnitude aftershock on Saturday, a day after powerful earthquakes devastated several neighbouring nations, leaving more than a thousand dead.

According to the United States Geological Survey (USGS), the latest tremor struck near Pyinmana, approximately 24 km from Nay Pyi Taw, around 2.50pm local time, with tremors felt across Laos, Thailand, and parts of China.

The aftershock occurred at a depth of 10 kilometres and impacted many of the same regions already battered by Friday's major quakes.

NDTV World, quoting USGS, said the region had already experienced at least 12 aftershocks since the initial major earthquake near Sagaing, with magnitudes ranging between 2.8 and 7.5.


The full extent of damage and potential casualties from the latest aftershock remains unclear as rescue and relief efforts continue, added NDTV World.

Mandalay, Bago, Magway, northeastern Shan State, Sagaing, and Nay Pyi Taw have been identified as the hardest-hit areas, Xinhua news agency reported.
