[0048] In step S101, natural earthquake information is acquired.

[0050] The corresponding website is a website for publishing official earthquake data of a country in some embodiments, for example, a website of the United States Geological Survey.

[0051] In some embodiments, the natural earthquake information is acquired by acquiring magnitude information, occurrence latitude and longitude information, etc. of natural earthquakes.

[0052] Step S102, filtering out target earthquakes based on set screening conditions.

[0053] In some embodiments, the screening conditions include the magnitude of natural earthquakes, the distance from the target instrument vehicle, etc. When the screening conditions include the distance from the target instrument vehicle, the following step S103 can be executed in a different order from step S102.
