- Prejudice and discrimination can lead to social tensions, which, if left unaddressed, can escalate into violence. For example, historical cases like the Rwandan genocide and the Holocaust were fueled by deep-seated prejudices and discriminatory beliefs.
- In societies where certain groups are marginalized or oppressed due to prejudice, the lack of intervention can lead to resentment and anger, ultimately resulting in violent uprisings. For instance, the civil rights movement in the United States was a response to systemic discrimination and prejudice against African Americans.
- Failure to address prejudice and discrimination can also lead to inter-group conflicts. In many parts of the world, ethnic or religious tensions have escalated into violent clashes due to the perpetuation of discriminatory attitudes and practices.
- In the absence of efforts to address prejudice and discrimination, individuals from marginalized groups may feel alienated and disenfranchised, leading to radicalization and extremist movements that resort to violence as a means of addressing perceived injustices.
- Overall, when prejudice and discrimination are not effectively addressed, they can create fertile ground for conflicts to escalate into violence, highlighting the importance of proactive measures to promote understanding, equality, and social harmony.
According to United States Geological Survey (USGS)- "Earthquake waves or seismic waves are the vibrations that travels through the earth's crust and mantle, caused by the sudden movement of rocks during an earthquake."

According to United States Geological Survey (USGS)- “Earthquake waves or seismic waves are the vibrations that travels through the earth’s crust and mantle, caused by the sudden movement of rocks during an earthquake.”
Types of Earthquake waves –
a) Primary Waves – These are compressional waves which travel through solid, liquid and gas .It causes ground compression and expansion.
b) Shear Waves -These are shear waves which travel only through solid materials.These are slower than primary waves.It causes ground deformation and shaking.
a) Rayleigh waves- These are rolling waves and these are most destructive wabe type which causes ground motion in circular motion.
b) Love waves – These are horizontal waves which cause ground motion perpendicular to direction of travel.They are less destructive than Rayleigh waves.
Emergence of Shadow Zones –
a)P-Wave Shadow Zone (105° to 145 ° from epicenter).
b)S-Wave Shadow Zone (105° to 105° from epicenter).
Understanding these waves and shadow zones will help the scientists in studying earth’s internal structure , predicting earthquake behaviour and will improve their hazard assessment.
