"We have coordinates, but the problem is that we can't find time, we can't find the intensity of earthquakes. ”

These are the two major problems that plague Shen Qi, time, place, and intensity, these three indicators determine how to deal with the possible earthquake.

As for whether the four sets of coordinates are accurate, Shen Qi doesn't know either, and it needs to be verified.

The four sets of coordinates are located in the North and South Pacific Oceans, and are related to the United States, Russia, and New Zealand.

This was a secret, and Shen Qi didn't dare to talk about it everywhere, otherwise it might cause panic among the local residents.

According to the data, there are 39 permanent residents of Unimac Island in the United States, 22 permanent residents of Nikolskoye Island in Russia, and 10 permanent residents of Campbell Island in New Zealand.

Although the three islands of Unimac, Nikolskoye and Campbell are far more numerous than humans, there are still very small numbers of humans on the islands, and there are also biologists or geologists who are engaged in scientific exploration in addition to the aborigines.

Out of the conscience of scientific research workers, Shen Qi immediately sent emails to the American earthquake network, the Russian earthquake network, and the New Zealand earthquake network.

In the email, Shen Qi identified himself, I am Shen Qi, a professor in the Department of Mathematics at Princeton, and after my calculations, I found that there is a possibility of an earthquake at a certain coordinate in your country.

Time of the earthquake, unknown.

Seismic intensity, unknown.

If you have recently detected an earthquake with a magnitude of 2.0 or higher on the Richter scale, please contact me immediately, thank you.

At the same time, Shen Qi sorted out a brief edition of the paper, entitled "Research on New Seismic Models".

In this popular science paper, Shen Qi describes the principle of earthquakes in concise language, with the core mathematical formulas he derives.

As for the specific deduction and calculation process of this formula, omitted.

Nothing is said about computer programming based on mathematical models.

In this article, Shen Qi only talks about the theoretical principles of the mathematical and physical model of earthquakes, and does not see any specific latitude and longitude coordinates.

What North Pacific, South Pacific, Unimac Island, Campbell Island, that is absolutely not mentioned.

Scientific research results on seismic models are not uncommon, and Shen Qi is not the first person to publish the results of seismic model research.

The world's most famous earthquake models include the Gutenberg-Richter model, the Bridge-Nopoff model, and so on.

The model is here, and whoever loves to predict will predict.

Anyway, I, old Shen, don't predict earthquakes in public.

Shen Qi hung the popular science version of the paper "Research on New Earthquake Models" on arVix, and took a long breath, my task has been completed.

Shen Qi is well-known in the United States, and the American earthquake network replied to Shen Qi as soon as possible:

"Professor Shen, your email has been received. ”

In just such a sentence, I can't see what the attitude of the American earthquake network is.

Later, the Russian earthquake network replied to Shen Qi, and the attitude of the fighting nation was more direct:

"We in the Russian Earthquake Network have thousands of people engaged in earthquake research, prediction, monitoring, thank you for the reminder, but we believe in our team, thank you. ”

New Zealand, which has the smallest land area, was the last to reply to Shen Qi, and the New Zealand Earthquake Network even mocked Shen Qi:

"The cats I have online have made more accurate predictions not long ago. In any case, I would like to thank Professor Shen for the reminder. ”

Hey, you're a New Zealander, you're actually sarcastic about me...... Shen Qi was still a little unhappy, regardless of whether his prediction was accurate or not, his starting point was out of kindness.

Theories are always ahead of application, unverified theories are related to natural disasters, who dares to believe them easily?

Once a national warning of a natural disaster is issued, the impact is enormous.

"You, hey, you did it anyway. Ou Ye was uneasy, and she saw Shen Qi's paper "Research on New Earthquake Models" on arVix.

Shen Qi explained: "This is just a purely theoretical research, and human beings have been systematically building seismic models since the 19th century, which is very routine work. Our ancestor Zhang Heng, his era was the Han Dynasty, was he arrested by the Han Dynasty government? No, no? Zhang Heng lived to be more than sixty years old, and he belonged to the long-lived group in ancient times, and did not arouse the anger of people and gods. ”

Ou Ye was still not at ease: "Qi, I always have a feeling of uneasiness......"

Shen Qi hung on arVix a conventional research paper on seismic model theory, which attracted some attention from the scientific community.

This paper is hung in the physics section of arVix, which is the second physics paper that Shen Qi has made public.

The first physics paper was a study of condensed matter physics and was published in PRL.

The mathematics and physics circles are talking more about Shen Qi's cross-border development, and not too many people really pay attention to Shen Qi's conventional seismic model papers.

Only a very small number of people in the world know that Shen Qi predicted specific coordinate locations where earthquakes could occur.

Shen Qi pays attention to news reports from the United States, Russia, and New Zealand every day.

The U.S. Earthquake Network, the Russian Earthquake Network, and the New Zealand Earthquake Network did not issue earthquake or tsunami warnings on Unimac Island, Nikolskoye Island, Campbell Island, and other sea areas.

A month has passed, and the world is at peace.

Life returns to peace, and Ou Ye gradually forgets Shen Qi's whimsy, this is her second semester of doctoral studies in Princeton, she is busy, and she has a project at hand.

Zhou Yu'an is very interested in the new seismic model proposed by Shen Qi, which involves the processing of some partial differential equations, which is the field that Zhou Yu'an is good at.

"Did you miscalculate?" asked Zhou Yu'an, who was drinking coffee in Shen Qi's office.

Shen Qi said while operating the mouse to browse the news: "It's normal to miscalculate, I also hope that I miscalculated, world peace, no disaster, is the situation I want to see the most." ”

As soon as the words fell, the International Seismological Center released an update on its official website:

"At around 17:32 GMT today, an earthquake of magnitude 5.5 on the Richter scale struck New Zealand, with an epicenter located 188 kilometers south of Campbell Island (56 degrees 34 minutes south latitude, 168 degrees 05 minutes east longitude) and an epicenter depth of 33 kilometers. ”

"This ...... There was an earthquake in New Zealand......" Shen Qi didn't expect the news to come so suddenly.

"This ...... Shen Daxian, you ......" Zhou Yu'an came to Shen Qi's side with mixed feelings, and paid attention to the latest news released by the International Earthquake Center.

It is inconceivable that a mortal can predict an earthquake.

An earthquake with a magnitude of 5.5 on the Richter scale, which means a catastrophe, is bound to cause harm to a country.

"Fortunately, the epicentre is located on the bottom of the Pacific Ocean, nearly 200 kilometers from Campbell Island in New Zealand, and there are only 10 permanent residents on this island, so they should be safe, and even if a tsunami hits, they have time to prepare in advance. "The two sets of coordinates that Shen Qi sent to the New Zealand seismic network were [55 degrees south latitude, 167 degrees east longitude] and [55 degrees south latitude, 167 degrees west longitude].

The New Zealand earthquake coordinates just released by the International Seismological Center are [56 degrees 34 minutes south latitude, 168 degrees 05 minutes east longitude].

This is 1 degree away from the coordinates predicted by Shen Qi before in latitude and longitude, and the error distance is close to 100 kilometers.

Zhou Yu'an swished in a cold sweat: "100 kilometers on the earth, only about 0.15 mm on the globe, Shen Qi, your prediction accuracy is already very high, you, you, you are terrible......
