Take a look at the theories behind why earthquakes occur, what makes them so hard to predict and the warning system technologies we rely on today.
--
In 132 CE, Zhang Heng presented his latest invention: a large vase he claimed could tell them whenever an earthquake occurred for hundreds of miles. Today, we no longer rely on pots as warning systems, but earthquakes still offer challenges to those trying to track them. Why are earthquakes so hard to anticipate, and how could we get better at predicting them? Jean-Baptiste P. Koehl investigates.

@ruei-jiunhung2887 3 года назад

As a researcher, I wanna put a clarification about the difference between earthquake 'warning' and 'prediction'. In seismology, we have a rigorous definition on 'earthquake prediction', which requires accurate location, magnitude and timing for a future earthquake, and it is thought somehow impossible to achieve now. earthquake warning, which is based on the early detection of seismic wave (so earthquake has occurred), sends out messages to the public. It's not a prediction.

About the vase... I am Chinese and I am proud of my culture and history. But the thing is many Chinese scholars are skeptical about the existence of this vase right now. The picture of the vase you see in the video is a recreation of the original model that people put together based on ancient articles without sufficient details. They tried several recreations and just failed to predict earthquake as the antient articles claimed. It could be that the emperor at that time didn't want to expose enough details in case the technology falls into enemy's hand, or it could just be a story created to make his kingdom sound more powerful. Well, it's all history now and we cannot really know which one is true. But a lot of Chinese scholars are recognizing this fact and proposing to change the textbooks about this vase until solid evidence says otherwise.

I wonder what cities, countries, would adopt a new unproven warning system that would require all citizens to evacuate the danger zones? I heard about a city somewhere that got a warning about a potential earthquake. It didnt happen (or it did but was small) and cost the city millions from relocating citizens and stopping tourists from visiting. Or Would the testing be done first without alerting cities about the potential problem? I wonder what % of accuracy would be required for cities to accept the system? Especially cities like San Fran, LA, and others with high daily GP.

But what about when the plates move apart from each other or collides with each other? Do earthquakes form that way too?

@prithvirajdewan1417 10 месяцев назад

To know exactly when an earthquake will occur, analysis of some sectional parts of nature's character is required. An important part is the sudden occurrence of events that cannot be predicted at the time of the attack. Now if we can analyze the nano-durations of that ultra-short time table, it will be seen that there is enough time to know it, and in this idea we will find a special character of nature, that is the expressive measurement of the message in the pitch-based characteristics of the sound in terms of frictional response of that time. In favor of which are all the sources of preparation according to the principle of sound. A conventional pitch preserves its existence by reacting to previous pitch dimensions. Therefore, the beginning of the preparation is stored in the sound frequencies in the carrying capacity of how long after the tension will come or occur

The circle of fifths invented by Pythagoras is characterized by the application of homophonic related harmonized chords while the melody is ascending but proceeds in the exact opposite direction. Similarly, if we want to know the prediction of earthquakes, we have to go against all the efforts made till date.

I wonder why scientists search water on Mars, while they don't solve the mysteries of the lithosphere, atmosphere, and even the biosphere. If an earthquake threatens to destroy Earth, would we find a way to prevent it or leave for another planet? I'd go with the first one. "The first way to discover everything is to start with your own." Anyways, good video, Ted Ed. Keep up the good work. :)
