How do Japanese predict earthquakes?
Advertisements
उत्तर
-
Measuring changes in sea level: Japan monitors sea-level variations, as sudden changes in the water level can indicate tectonic shifts that may lead to earthquakes.
-
Magnetic field variations: Changes in the Earth’s magnetic field are also used to predict earthquakes. This method is based on the idea that the Earth’s magnetic field can be disturbed by shifts in the Earth’s crust.
