Japan suddenly encountered an "unknown earthquake", a large-scale tsunami flashed, is it an earthquake or an undersea landslide? Do you understand?
If you scrolled through your friends this morning, you probably already know: Japan experienced a rare "unidentified earthquake", followed by tsunami warnings in multiple coastal areas. But wait, we dug deeper and found that this seismic event was not simple.
A sudden earthquake woke up Japan. At 5:25 a.m., the vicinity of Torishima in the Ogasawara Islands in Japan became the epicenter of the earthquake. You might say, "It's Japan again, aren't earthquakes a common occurrence?" "But this time, even the Japan Meteorological Agency was a little confused because they found that the depth and location of the earthquake were very blurred.
Imagine what you would do if your home earthquake warning system told you, "There was an earthquake, but we don't know how magnitude it was." Yes, regardless of the size, people will be nervous, after all, we all know about nuclear power plants and volcanoes in Japan. But the good news this time is that the earthquake did not cause anomalies in nuclear power plants and volcanic eruptions.
However, the newly lowered heart was lifted up again - the tsunami attention report followed, and the data of the tide level change also proved that the tsunami had arrived. Some areas have even observed tsunami waves up to 60 centimeters, what's going on? Even the U.S. Geological Survey jumped out and said, "This is a magnitude 4.9 earthquake." "But wait a minute, can a magnitude 4.9 earthquake really cause such a large tsunami?
This reminds me of another possible "killer" of earthquakes - submarine landslides. Imagine the sudden loss of stability of large swathes of seafloor sediment, resulting in a huge landslide. When this rare phenomenon occurs, its impact may be beyond our imagination. Some experts speculate that this time it may not be just an earthquake, but an earthquake accompanied by a submarine landslide.
Five days ago, a 6.6 magnitude earthquake struck the same area, doesn't it feel familiar? Yes, this is also near Torishima in the Ogasawara Islands. Is this high frequency seismic activity a sign that the terrain of the sea has begun to become unstable, leading to today's submarine landslides and tsunamis?
Of course, this is just my speculation, and some netizens suspect that it is a volcanic eruption or other reasons. But whatever the cause, it's important that we care. Japan's experience has taught us that prevention is always more important than remediation in the face of natural disasters.
For everyone, no matter where you are, your safety is tied to these fluctuations of nature. Therefore, please keep an eye on weather and disaster information to provide a safe environment for yourself and your family.
Finally, this article is what I wrote based on all the information currently available. If there are any new developments or information, I will update you all immediately. Remember that nature is always full of unknowns, but we can ensure our own safety by knowing and precautioning.
