  Next, using the analysis result of step S317, it is determined whether or not a P wave is detected (step S319).

  Furthermore, you may return to S313 after step S331. By doing so, it is possible to cope with the case where the S wave gradually increases.

It becomes possible.

  Moreover, according to this embodiment, even if it is a case where P wave detection fails, it becomes possible to prevent an earthquake disaster by detecting S wave.
