The elastic rebound theory a. explains folding of rocks. b. explains the behavior of seismic waves. c. involves the sudden release of progressively stored strain in rocks, causing movement along a fault. d none of the preceding

Explanation / Answer

11. Earthquake Precursors that have occured before earthquake:

analysis of existing Earthquake Precursors data leads to a conclusion and this Earthquake Precursors are classified into 3 types:

EXPANDING YOUR KNOWLEDGE:

part I

favours of earthquake:

against earthquake:

nature never obey any rules or pattern

part II

a prediction were made today within a month and a large earthquake would occur today nearby my community :

if the prediction is good enough or a successfull prediction is there then it will greatly reduce the loss of life ,economic damage, by permitting dangerous buildings and bridges to be evacuated, tsunami prone area to be cleared and hospitals, rescue team to be prepared and /or standby.

2. most earthquakes occurs at plate boundary:

plate interacts with each other at -

cause of earthquakes in the interior of plate:

intraplate or plate interior earthquake mainly caused by the stresses within a plate.since plates move over a spherical urfac and created zone of weakness. intraplate earthquakes happen mainly for this zone weakness. it also may takes place along ancient faults and rifts. around 5% of earthquake in all over the world is intraplate earthquake.
