DRRR QUARTER 1 Lesson 11 - Earthquake Hazards and Their C.

Which earthquake hazard refers to the vibration of the ground caused by seismic waves?

• Ground shaking

• Ground rupture

• Liquefaction

• Ground subsidence

Why is liquefaction dangerous during an earthquake?

• It weakens the ground and affects building stability

• It strengthens soil and supports structures

• It only affects mountainous regions

• It occurs long after the earthquake

A community is built on soft, water-saturated soil. Which hazard should residents prepare for most?

• Liquefaction

• Ground rupture

• Tsunami

• Ground subsidence

How does liquefaction differ from ground shaking in terms of impact?

• Liquefaction weakens soil, while shaking stresses structures

• Liquefaction causes waves, while shaking floods land

• Both only affect coastal areas

• Both occur without damaging buildings

Which situation shows the BEST understanding of earthquake hazard impacts?

• Identifying weak structures and planning evacuation routes

• Ignoring hazard maps until an earthquake happens

• Relying only on rescue teams after an earthquake

• Preparing only for ground shaking and no other hazards
