=== Vp/Vs farqi ===
[[Seysmologiya]]dagi yana bir metod ''V''<sub>p</sub> va (''p''-toʻlqin tezligi) va ''V''<sub>s</sub> va (''s''-toʻlqin tezligi) nisbati oʻzgarishini qayd etishga asoslanadi. Bu nisbat tosh qobiq siqilayotgan paytda oʻzgaradi, deb taxmin etilgandi. Bu metodga tayanib faqat bitta zilzila (1973-yilgi 2,6 magnitudali [[New York]] zilzilasi) muvaffaqiyatli bashorat qilingan.<ref>{{citation
