Destructive earthquake have magnitudes higher than _________ on RIchter Scale.

Options

A. 4
B. 6
C. 7
D. 2

Answer

To determine the magnitude on the Richter Scale that classifies an earthquake as destructive, we can follow these steps:

### Step 1: Understand the Richter Scale
The Richter Scale is a logarithmic scale used to measure the magnitude of earthquakes. It categorizes earthquakes based on their magnitude.

### Step 2: Identify the Magnitude Ranges
- **Magnitude 1 to 3**: Minor earthquakes, usually not felt.
- **Magnitude 3 to 6**: Moderate earthquakes, can be felt but usually cause minimal damage.
- **Magnitude 6 and above**: Destructive earthquakes.

### Step 3: Determine the Threshold for Destructive Earthquakes
From the information above, we can see that earthquakes with a magnitude of **6 and above** are considered destructive.

### Step 4: Answer the Question
The question asks for the magnitude higher than which earthquakes are classified as destructive. Since destructive earthquakes start at a magnitude of 6, we conclude that destructive earthquakes have magnitudes higher than **6** on the Richter Scale.

### Final Answer
Destructive earthquakes have magnitudes higher than **6** on the Richter Scale.
