Why Massive Earthquakes Shorten the Length of a Day

[krishpatel]

Fun fact: Some scientists are considering to make 1 min=59 seconds because of these shifts in earth's rotation speed. This might affect the leap year system, as we may no longer need 29th February every 4 years

Oh so that's why I woke up late the next day

[lexibachman]

let’s gooo school shortened by 1.8 centimeters probably

Thx for the hard work and research u make to give us something to watch❤️

Certainly! An earthquake is a sudden and violent shaking of the ground, often caused by the movement of Earth's tectonic plates beneath the Earth's surface. Here's a simplified explanation of how an earthquake works:

1. **Tectonic Plates:**
The Earth's outer shell, called the lithosphere, is divided into several large and small pieces known as tectonic plates. These plates float on the semi-fluid asthenosphere beneath them.

2. **Plate Boundaries:**
Tectonic plates are constantly moving, but they do so very slowly. When these plates interact at their boundaries, various geological phenomena occur. There are three main types of plate boundaries:
- **Divergent Boundaries:** Plates move away from each other.
- **Convergent Boundaries:** Plates move towards each other.
- **Transform Boundaries:** Plates slide past each other horizontally.

3. **Buildup of Stress:**
As plates interact at their boundaries, stress can build up along faults (cracks in the Earth's crust). This stress occurs because the movement of the plates is not always smooth; they can get stuck due to friction.

4. **Release of Energy:**
Eventually, the stress overcomes the friction, and the accumulated energy is released in the form of seismic waves. These waves travel through the Earth, causing the ground to shake – this shaking is what we feel during an earthquake.

5. **Focus and Epicenter:**
- The point inside the Earth where the earthquake originates is called the **focus** or **hypocenter**.
- The point on the Earth's surface directly above the focus is called the **epicenter**.

6. **Seismic Waves:**
- The released energy travels in the form of seismic waves. There are two main types: primary waves (P-waves) and secondary waves (S-waves). P-waves are faster and can travel through solids and liquids, while S-waves can only travel through solids.

7. **Surface Effects:**
- When these waves reach the Earth's surface, they can cause the ground to shake, leading to the destructive effects we associate with earthquakes, such as ground rupture, building damage, and soil liquefaction.

In summary, earthquakes are a result of the dynamic movement and interaction of tectonic plates, leading to the release of accumulated stress in the Earth's crust.

The length of earths day used to be as little as 10 hours. Over billions of years it has sliwed to 23 hours 56 minutes

[Tophat]

So that is basically the reason why this year is going by so fast now

[GobsTheFlobs]

There are 16 major earthquakes per year, multiply this by 1.8 = 28.8 microseconds. Convert microseconds to milliseconds = 0.0288 milliseconds. Multiply this by 1, 000 years = 28.8 seconds. MY GOD THE WORLD WILL END! The world will probably end before the next 1, 000 years…

Which software did you use to make this wonderful animation?

[ljoden]

So that why i didnt get enough sleep today

I thought it was that it was so strong that the force created by the earthquake pushed onto the earth pulling it axis by 17 cm and making it rotate faster by 1.8 µs

Jesus is coming back soon. Matthew 24:6-13 You will hear of wars and rumors of wars, but see to it that you are not alarmed. Such things must happen, but the end is still to come. 7 Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places. 8 All these are the beginning of birth pains. 9 “Then you will be handed over to be persecuted and put to death, and you will be hated by all nations because of me. 10 At that time many will turn away from the faith and will betray and hate each other, 11 and many false prophets will appear and deceive many people. 12 Because of the increase of wickedness, the love of most will grow cold, 13 but the one who stands firm to the end will be saved.

Thanks. So then I'm not crazy to feel that the days have been coming and going just a tad bit faster than were before.

[morellana]

I know one thing that cause tsunami is called taco bell in a toilet bowl😂😂😂😂

[michaelparker]

Hmmm 🤔 interesting,
could it also speed the rotation?

[toast]

17cm and 1.8 microseconds, we’ll never recover!!! On a side not imagine how different days were in the time of the Dinos

[kylecrook]

Wtf is a mirco second lol i know miliseconds but tf is micro lol

[Militaman]

I'm glad by earth axis you mean the axis it turns at, not the axis powers

[crusaderedit]

something i never knew about im first too

[DAFERDBDR]

Volcano do that not earth quick also change magnatic field and climat changes. By god determination
