In this world we never know which accident or tomorrow will come first. In the face of natural disaster , humans are very small. Whether it is an earthquake, typhoon , or tsunami, its power is devastating to mankind. However, if the tsunami is related to the desert, many people probably think it is a fantasy. You know, there are all kinds of strange things in this world. Recently, a rare tsunami occurred in the desert.
is right, it’s a tsunami in the desert. What’s going on?
tsunami occurred in the desert, and the waves reached 1.2 meters high
We all know that the coldest place in the world is Antarctic, but they don’t know that the hottest place is in the desert of , California, USA - Death Valley . is not only very hot here, but also extremely dry. It is very low at altitude and is surrounded by mountains.
1913, a scientific researcher found that it was as high as Fahrenheit 134.1 degrees . Especially in recent years, the Death Valley in the United States has repeatedly set high temperature records, and the world has given it many titles such as "Dry Bone Valley" and "Extinct Crater". Many people are full of fear of Death Valley, because many gold diggers die when they travel through Death Valley, so Death Valley over time is an ominous place for many people.
There is a cave in Death Valley that is very special. It is called Devil Cave . Like Death Valley, it was a simple cave at the beginning, because many explorers entered the cave to explore under the trend of curiosity. After that, there was no news, and finally the title of "Devil Cave". The Devil's Cave is a limestone cave with a lot of water inside, with a depth of up to a hundred feet.
Recently, according to relevant US media reports, a 7.7-magnitude earthquake occurred in Mexico , which is undoubtedly a huge disaster for the Mexicans. Little did they know that shortly after the earthquake, the Demon Cave in Death Valley, California, USA, had an amazing and extremely rare "desert tsunami" due to the shock wave of the earthquake. At that time, the height of the waves was as high as 1.2 meters.
Some netizens left messages saying: "It is really rare to have 1.2 meters of waves in a drought and water-deficient desert area. "Why does a tsunami occur in the desert? The earthquake in Mexico is far away from here. Why does it have such a big impact?" "It's really the first time I heard that a tsunami appeared in the desert. It's really unusual."
Why is the Devil's Cave affected by the Mexican earthquake? Will its scope of influence be expanded?
Want to find out why the Devil Cave in the Death Valley of the United States was affected by the Mexican earthquake, including whether its impact will be expanded? We must first understand the earthquake impact range, magnitude , and quake source. You should know that the larger the magnitude of a place in , the shallower the depth of the source will be, and the greater the range of the earthquake will affect. The earthquake in Mexico was magnitude 7.7, with a depth of 15 kilometers. This kind of earthquake magnitude not only belongs to the strong earthquake range, but also shallow-source earthquakes with a depth of less than 70 kilometers.
The energy suddenly released in the earth's lithosphere produces seismic wave and will cause vibration on the earth's surface, and the intensity of the earthquake is different. Seismic activity in a region is the frequency of seismic experiences over a specific time period, and the seismic energy release rate is the average seismic energy release rate per unit volume. In addition, most earthquakes occur far below the surface, with a ring of fire with a depth of no more than tens of kilometers. When the depth of the focal focal focal depth is greater than 70 kilometers and less than 300 kilometers, it is called a medium-depth earthquake.
The earthquake intensity in Mexico is magnitude 7.7, and this kind of earthquake is an intensity earthquake. is 2414 kilometers away from the Devil Cave in the Death Valley of the United States, so the shock wave caused is very strong. For example, when an liquefied gas tank explodes, because the shock wave generated by the explosion is very strong, buildings less than 2 kilometers away from it will be affected and the glass will be shattered. and the power of a magnitude 7.7 earthquake is equivalent to the power of 35 Hiroshima atomic bombs. The impact of this earthquake in will be very large, but as for whether the impact will continue to be expanded, we are not sure at present.
However, it was strongly affected in the devil cave that had water all year round. The moment the earthquake occurred, due to the violent vibration of the ground, it could instantly stir up 1.2 meters of waves, but this was not a real tsunami.
In fact, this is not the first time that the Devil's Cave has caused a desert tsunami due to an earthquake. As early as 2019, an earthquake occurred in Chicrest, which also had an impact on the Devil's Cave. At the same time, in addition to the wonder of the desert tsunami, what is threatened is the rare fish living here - phimosis . is the unique fish here, and thorn fish mainly uses algae as food. Due to the desert tsunami in Devil Valley, many algae will be washed away, which poses a great threat to the living environment of the thornfish.
In addition to the Demon Cave in the United States being affected, it is understood that there was also a tsunami in the Pacific. It is reported that due to the impact of the Mexican earthquake, waves more than three meters high have been raised on the Pacific Ocean. According to recorded data in a monitoring station of a university in Mexico, sea level rose by 1.24 meters.
In addition, there were serious casualties in the area where the epicenter was located. Many people who escaped said with emotion: "It's so terrifying. This is the biggest earthquake I have ever experienced in my life." "When the earthquake occurred, I just arrived at the classroom and the entire roof began to shake. It is no exaggeration to say that I felt that the whole city was in fear." The impact of this earthquake on the psychology of people in Mexico was particularly serious. After the earthquake, residents' electricity use has also become a serious problem. About 900,000 users have been affected by electricity use. It will take some time to restore electricity as soon as possible.
Why do earthquakes occur frequently in Mexico?
has relevant data statistics. Since Mexico entered the 1980s, there have been three earthquakes of more than magnitude 8 and above, and countless earthquakes below magnitude 7 are numerous. According to statistics from the Mexican Earthquake Bureau, if particularly strong earthquakes are excluded, at least 40 earthquakes of large and small will occur every day.
So, why do earthquakes occur frequently in Mexico? In fact, this is closely related to Mexico's geographical location. The location of Mexico is just in the three-legged position in the Pacific, North American and Cocos in the eastern Pacific. , when plates are close to each other, the friction between plates continues to rise, the pressure generated during the period is getting greater and greater. When the force of mutual squeeze reaches its limit, the pressure will eventually be released in the form of an earthquake.
The earthquake in Mexico has also sounded a wake-up call for us humans. With the occurrence of extreme weather in the future, the faster the glaciers melt, the easier it is to increase the number of earthquakes. Especially in areas with frequent earthquakes, it is necessary to prevent problems before they happen. Only in this way can the casualty rate be reduced.
