According to the Japan Broadcasting Association (NHK), at around 17:59 local time on the 9th, 6Magnitude 0**, the seismic intensity is 5 weak.
*, like a grumpy giant in nature, beats on the earth from time to time, attracting attention and talk. They silently accumulate energy and release it suddenly, like the roar of a wild beast, making human society tremble. Every moment when the earth shakes the mountains touches the hearts of people all over the world: whether it is you and me who are far away from the epicenter, or they are in the disaster area, the attention has never been far away from our lives.
*, a simple but heavy word that often conjures us up of devastating scenes – collapsed buildings, broken roads, life and death. This sudden "surprise" in the natural world, sometimes a merciless blow, has a profound and multifaceted impact on human society. Not only does it claim countless precious lives, but it can also lead to huge economic losses, paralyzing social functions, and bringing lasting trauma to the minds of survivors. Silent, yet deafening, reminding us that we must take it seriously and work to mitigate the catastrophe it brings.
*, like a strong heartbeat in the heart of the earth, is the vibration produced by the sudden fracture and sliding of the earth's crust. Imagine accumulating energy beneath the earth's surface when huge plates of rock inevitably collide, squeeze or pull against each other as they move slowly and continuously. These energies are like tightened rubber bands, which will be released at some point, and the vibrations are the result of this energy release, and the vibrations spread from the source to the surroundings, like stones thrown into the water to stir up layers of ripples, touching every corner of the earth.
When the earth's roar spreads through the waves, scientists are like detectives, using sophisticated instruments to measure its strength. ** The size we usually use ".MagnitudeThe word to describe. You can think of it as a decibel meter that measures loudness, but here we're measuring energy release. One of the most well-known measurement methods is called:Richter scale, also known as local magnitude (ML), is a mathematical formula that reflects the magnitude of ground motion. To put it simply, the Richter scale scores each jump of **, and there is no upper limit on the full score. For each 1 unit increase in scale, the amount of energy released increases by approximately 316 times. In addition to the Richter scale, there are more elaborate scales such as moment magnitude (MW), which more accurately reflects the total energy released by the source. There are also surface wave magnitude (MS) and body wave magnitude (MB), which specifically measure the energy of ** waves propagating across the Earth's surface or body. Around the world, monitoring stations are dotted to capture every jump of the wave, ensuring that even the gentle whisper of the earth is hidden.
Global** monitoring networkIt's like a huge system of stethoscopes, distributed all over the world, listening to the movements in the depths of the earth. This system consists of thousands of stations, which carry sensitive instruments that record every tiny tremor of the Earth without sleep. The collection of data is a delicate work, and each station transmits the recorded wave information to the data center in real time. These data centers, such as the USGS (United States Geological Survey) in the United States and the global IRIS (International Union for the Study of Science and Physics of the Earth's Interior), act like the world's pulse processing room, collecting and analyzing data from all over the world. Through this global collaboration, scientists are able to track every ** that happens on Earth in real time, whether intense or faint. This data is not only related to the efficiency of emergency response and rescue efforts, but also useful for forecasting research, giving us a deeper understanding of the planet's temper and behavior.
Pacific Rim ** Belt,Figuratively known as the "Ring of Fire", it is like an active dragon on Earth, winding its way from the west coast of South America, through North America, through Alaska, and then winding down through Japan, the Philippines, and all the way to New Zealand. In this belt, the collision and friction of the Earth's tectonic plates makes it the most frequent region in the world.
Whenever this "dragon" turns over, it may trigger **, even the kind of big ** that requires the use of two hands to exponential magnitude. Not only are there many eruptions here, but volcanic eruptions are also very common. Just as the earth has opened its safety valve in this area, allowing the pressure to be released from within, this spectacular natural phenomenon unfortunately has sometimes catastrophic consequences.
Himalayan ** belt,It is like a sculpture workshop in nature, where the Himalayas, the world's tallest mountain range, were born. It was formed thanks to a long-term wrestling between the Indian and Eurasian plates. As the Indian plate pushes northward and collides with the Eurasian plate, these massive plate movements are like the big hands of the mountain-building that create such spectacular peaks.
However, it is the continuous squeeze of this plate that has also made this area an active hot spot. From time to time, loud noises from deep underground remind people that the land is still growing and turbulent. Here, it's like a sudden flash of lightning in the sky, which doesn't happen often, but each time it can make a drastic difference.
The Great Rift ValleyLike an unhealing scar on the planet, it stretches from the Red Sea in Ethiopia to Zimbabwe and through East Africa. It is a land that is gradually witnessing the separation of the continental plates, where the African plate is slowly cracking apart, creating a series of spectacular cliffs and canyons. In this process, as the earth's crust is pulled and moved, stress continues to accumulate and release, and ** often occurs. Although the Great Rift Valley is less active than the Ring of Fire, it is a living textbook for geologists, showing us how the dissolution of continental plates can evolve into deep-sea basins. These activities are like the brushstrokes of nature, drawing the outline of the map of the future.
