Learned something interesting from a tv programme today. Penyelidik Jepun discovered that electromagnetic wave terhasil a few moment sebelum earthquake happens. Ini sbb, kejadian gelombang radio dari chiba, boleh kedengaran kat hokkaido beberapa ketika sebelum earthquake yg berlaku kat Miyagi, Sendai. Plus tempoh masa gelombang radio; ex. Hokkaido menerima gelombang Chiba, tempoh masa yg Hokkaido dapat terima gelombang tu hampir berkadar terus dgn kekuatan earthquake tu. Sbb itu, skarang derang memasang antena FM kat byk tempat, supaya apabila gelombang radio FM yg luar dari sesuatu kawasan tu diterima tiba2...maknanya ada kemungkinan earthquake berlaku.

Plus, daripada gelombang elektromagnet yg terhasil dari permukaan bumi, awan terbentuk kesan daripada wave tu. So..bentuk2 awan pelik can be seen before earthquake datte. Cuma, keluasan/corak wave tu tak dapat di jelaskan.
