Sumatra-A Tale Of Two Earthquakes & A Tale of Two Upcoming Tectonic Plates
Ғылым және технология
Data released in the Sept 2012 Nature journal yielded new information about the 2012 Sumatra earthquake. Surprising elements of this earthquake include, that it was both the largest intra-plate earthquake and the largest strike-slip earthquake ever recorded, plus the 10th largest earthquake of any kind ever recorded. Not to mention the most complex.
In 2004 a Magnitude 9.1 interplate subduction earthquake triggered a tsunami that killed over 230,000 people. Yet a nearby magnitude 8.7 intraplate earthquake in 2012, caused little damage and generated minimal ocean waves. Although the earthquakes appeared similar in magnitude and were close in proximity, they were caused by different tectonic processes related to the greater Indo Australian plate.
This animation describes the different tectonic settings of the two plates, and how the Indo-Australian plate seems destined to become two distinct tectonic plates: the Indian and the Australian plates.

this is the reason why we must updating our knowledge about the number of plate tectonics in our earth, because it never been static, it always dynamic.
Wow, this is the first I've heard about this information. Interesting. I want to know more!

@@boopshanaa I'm not sure why you said too bad but I'm really interested in plate tectonics. I live in the Pacific Northwest and have been watching everything I can on the subject. There isn't much information about the 2004 tsunami from what I've found. This video is the best video I've seen for this part of the globe and because of it, I'd like to see more.
Thanks for sharing your knowledge in this video, I live in Sumatra and we really need this information for mitigation in the future
Excellent video
Such a good explanation 👍
What an excellent video!
Awesome work.
Wav just too good of an explanation ❤
This is important to avoid the changing future
I'm still remember that time, so hard time for indonesian people
Thank you
You have some of the best

Graphics when explaining all these earthquakes thank you so much for taking the time to do it
Great presentation! The narrator sounds a lot like Cybill Shepard.
That could be a Transform boundary between the Indian Plate and the Australian Plate.
so the quake because a diffrent speed of Indian Plate and Indo-Australian plate right?
few people at acheh hearing louder bang at night before earthquake events.this must probaly hidden true that must be big explosion do at sea bed to shock plate.
The 2012 earthquake was a magnitude of 8.6!
Good presentation for my country...thanks
1. WATER AREA so it is necessary to consider the construction of a road on water that is safe and sturdy with water-resistant and very strong construction materials, in driving the base of the nails the poles must be deep because of the spongy nature of the soil moving, shifting and very high corrosive occurrence, special technical considerations are needed to guarantee the long term line and high savety_study case area 2. The riverbed through which heavy tonnage transport ships pass must take into consideration the technique of deepening the riverbed, to anticipate overflowing water due to siltation of the river and sea water entering the river flow which results in increasing the level of the river level and the large volume of water that can overflow to all river banks 3. The banks of the river, with the volume and number of sources of incoming water, must have a high safety area to avoid collapsing of the soil on the banks of the river and tends to be soft like a sponge 4. The building built has deep and strong piles and is high above the water surface in a zig-zag shape or the letter "S", winding 5. It is suggested that Pertamina water and special high-risk industrial managers should be for BUFFER AREA and away from settlements and government activities as well as being a more dominant port with other synergistic activities that integrate maritime_suggestion🙏[[Nora, 06_07_2023; 06:55 WIB] Hopefully useful🙏📖🌏🎧🌏
You forgot the watercolumn buoys that show the ocean floor lifted more than 1000ft when they shut them off. Big surprise!!!!
Very good. I've often wondered how plates, & hence their boundaries, were ever formed in the first place and i guess this may go some way to explaining it. At some stage, possibly due to the stresses of Earth's spin, which was mores rapid than today, & the pull of the moon, which was closer, & the pull of the sun, there would have been a tendancy for movement of the crust but it would have met resistance. There is no reason why new boundaries cannot still form.
Scary world
So, We live in dead zone, right???
Earthquake, tsunami, eruption of volcano We still a life
Easy to miss the simple comment ever recorded.
what doe australians do ? if these theries are correct that means .... Australia will sink into the mantle?

Maybe, maybe not. If it keeps going that far, then the continental part (floating, with all the land on) may break off from the oceanic part (sinking, under the ocean) leaving two more plates. I'm sure there's a PhD in there for someone to gather the data, and do the maths on plate density, strength and fracture areas, and suggest a likely future for Australia; either way it'll be a long time before it happens - I can't see property prices being affected for a few million years.

It will be a part of the Eurasian continent like India, I guess. Oceanic crusts are heavier, so they sink under the lighter and thicker continental land crusts. Two continental crusts will just collide and deform

No. Australia is composed of continental rock. The crust is made of either oceanic crust or continental crust. Continental crust us less dense than oceanic crust. Oceanic crust is more likely to subduct into the mantle. If Australia were to drift into another continent, Australia would be pushed upward, like what's happening with India and Asia, forming the Himalaya mountains.

Sunda Plate doesn't exist because there's no fault line at the northern Southeast Asia. It is still in Eurasian Plate.

From Wikipedia: The Sunda Plate was formerly considered a part of the Eurasian Plate, but the GPS measurements have confirmed its independent movement at 10 mm/yr eastward relative to Eurasia. en.m.wikipedia.org/wiki/Sunda_Plate

Fault line exists at the northern South east Asia but its as not tectonically active.
Dear Sir/Madam I discovered earthquake root cause and way to resolve earthquake Earthquake not due to tectonic plates movement but Earthquake due to liquid molecules turn into gas molecule due to heat or chemical or bacteria - gas arise out of ground cause earthquake Earthquake just like pressure cooker Technically earthquake root cause due to heat attract cold and cold attract heat which leads to liquid molecules turn into gas molecules Most of earthquake due to volcanic activities Earthquake Prediction: We can Predict Earthquake few minutes before earthquake by Monitoring gas molecular arise out of under ground by using sensor to monitor gas molecular arise out of under ground We can also able to predict volcanic eruptions too with the same way Resolve earthquake: If we put holes to release gas molecules from ground mean we can resolve earthquake

Very interesting. Where do you work or go to school? 1) Both things can be true: Your theory of liquid molecules converting to gas molecules and needing to push up and out of earths crust, AND the fact of what ever is going on under the tectonic plates causing them to move which in turn causes the plates to collide and causes earthquakes. The plates cause the earthquakes and the gas molecules cause the movement of the plates..if that is in fact true.. 2) Be careful when announcing a change to an entire paradigm of written books. Either that information will be previously known and accepted as part of what is already true, or, it will be rejected as pseudo science and they will go to any lengths to make a mockery of whoever tries to change the books on something. I’ve learned through years of research in various things that the so called “experts” have invested their whole lives into what they preach and if a person or piece of information happens to be contradictory to their gospel, they will go to any lengths to defend their career and make a mockery of the opposing viewpoint. Take care!
