Survei sesar Opak

Ini gambar pak Udi, bu Rina dan penulis saat survei penelitian sesar Opak di Bantul Oktober 2007 kemarin. Yang jelas kalau geofisika tidak saja melihat "singkapan-singkapan" saja tetapi juga harus "memasukkan" sesuatu ke dalam bumi

OUTLINES COURSE

Tittle: Seismologi (seismology)

Code number/SKS:PAF 373/ 2 SKS

Short description:
Seismology is a minor on geophysics in third semester, consist of historical development and the topics of global seismology, concepts of elasticity and seismic waves ( stress-strain relationship, equation of motion, wave equation, dispersion, and free oscilation and tsunami), seismogram interpretation (nomenclature, locating earthquakes), determination of Earth structure, and seismic sources (stereographic projection, focal mechanism, seismic moment tensor, and seismic energy and magnitude)

Standard competence:
After finish this lectur the students can describe concepts of elasticity and seismic waves, can interpret seismogram, can determine epicenter, can calculate earthquake magniudes, and solve problems in seismic source mechanism.

Seismologi

Salam,
Mungkin masih ada yang belum mengerti tentang gempa, sumber dan hal-hal yang berkaitan dengan gempabumi? Ada baiknya anda belajar tentang seismologi. Di Fisika Undip seismologi diberikan di semester gasal 2 SKS
