1. Sizes: 130 x 93 x 52mm
2. Material: ABS + metal

4. The earthquake happened in vertical shake (P wave), and after it, the destructive horizontal shake (S wave) came
5. The P wave has shallow earthquake (felt around 3 to 8 seconds later) and deep earthquake (felt around 30-40 seconds l
later),according to the strength of the earthquake, the magnitude of the S wave has 1 to 7 degree or over.
6. We all hope we can foresee the earthquake will come when the P wave happened
7. The P wave is the vertical wave, no matter the shallow earthquake felt 3 to 8 seconds later or the deep earthquake felt 30 to 40
seconds later, it doesn't mean the strength of the following S wave earthquake
