An earthquake occurs at a convergent boundary. The earthquake has a high magnitude, and an observer reports the earthquake having low intensity. Which statement about the earthquake is correct?(1 point)
Responses
The earthquake was caused by plates moving apart. It did not release much energy, but the observer saw a lot of damage.

The earthquake was caused by plates moving together. It released a lot of energy, but the observer did not see much damage.

The correct statement is: The earthquake was caused by plates moving together. It released a lot of energy, but the observer did not see much damage.
To determine the correct statement about the earthquake at the convergent boundary with high magnitude and low intensity, we need to understand the terms 'convergent boundary,' 'magnitude,' and 'intensity.'
A convergent boundary is a type of tectonic plate boundary where two plates are colliding and moving towards each other. This collision can result in the formation of mountains, volcanic activity, and earthquakes.
Magnitude refers to the size or strength of an earthquake, which is usually measured using the Richter scale. It is a logarithmic scale, meaning that each whole number increase on the scale represents a tenfold increase in the amplitude of the seismic waves.
Intensity, on the other hand, refers to the effect or impact of an earthquake on the Earth's surface and human-made structures. It is measured using the Modified Mercalli Intensity (MMI) scale, which ranges from I (not felt) to XII (total destruction).
Based on the given information, the earthquake occurred at a convergent boundary, had a high magnitude, but was reported to have low intensity. From this, we can deduce that:
The correct statement about the earthquake is: The earthquake was caused by plates moving together. It released a lot of energy, but the observer did not see much damage.
This is because when plates are moving together or converging, they can generate powerful earthquakes with high magnitudes, resulting in a significant release of energy. However, the fact that the observer reports low intensity suggests that the earthquake did not cause much damage or significant shaking at the surface.
