Berikut ini adalah pertanyaan dari heniharyani78 pada mata pelajaran B. inggris untuk jenjang Sekolah Menengah Atas
Earthquakes are the vibrations caused by rocks breaking under stress. The undergroundsurface along which the rock breaks and moves is called a fault plane.
The size or magnitude of earthquakes is determined by measuring the amplitude of the
seismic
waves recorded on a seismograph from the earthquake. These are put into a formula
which converts them to a magnitude, which is a measure of the energy released by the earthquake.
For
every unit increase in magnitude, there is roughly a thirty-fold increase in the energy released.
A magnitude 8,6 earthquake releases energy equivalent to about 10.000 atomic bombs of the
type developed in World War II. Fortunately, smaller earthquakes occure much more frequently
than large ones and most cause little or no damage.
Earthwuake magnitude was traditionally measured on the Richter scale. It is often now
calculated from seismic moment, which is proportional to the fault area multiplied by the average
displacement on the fault.
The focus of an earthquake is the point where it originated within the earth. The earthquake
epicente is the point on the Earth's surface directly above the focus.
