Which of the following devices detects ground vibrations caused by seismic waves and converts
them into electrical signals to help scientists analyze earthquakes?
Seismic Sensors
Which system provides communities with a few seconds to minutes of notice before destructive
shaking arrives, allowing time to prepare and reduce risks?
Early Warning System
Which of the following statements best describes the primary benefit of using computational
simulation in earthquake engineering?
A. It eliminates the need for any physical testing of structural systems.
B. It replaces traditional design codes with machine learning algorithms.
C. It enables the prediction and analysis of structural and geotechnical responses to seismic
loading, improving design resilience and risk assessment.
D. It focuses solely on modeling electromagnetic effects in civil structures.
It enables the prediction and analysis of structural and geotechnical responses to seismic
A science documentary shows how PHIVOLCS monitors active faults, collects ground
deformation data from satellites, and studies past seismic events to understand earthquake
behavior. Despite these efforts, the narrator explains that scientists still cannot predict exactly
when and where the next major earthquake will occur.
Which statement accurately explains why this remains impossible?
A. Because even though faults are monitored, the buildup of stress and the exact point of
rupture occur suddenly and cannot be measured precisely.
B. Because most earthquakes happen too deep underground for instruments to detect any early
signs.
C. Because satellites and sensors are still unable to identify which fault line will move next.
D. Because the data collected from past earthquakes are not enough to forecast future ones
with full accuracy.
The buildup of stress and the sudden rupture along faults occur
unpredictably, making exact earthquake prediction impossible.
this Construction technique transforms preconstruction planning. it allows construction teams to
overlay virtual designs onto physical spaces, enabling a clear understanding of how a project
will integrate with its surroundings. Architects and engineers can use it to identify potential
conflicts in real time, such as clashes between structural elements or services.
