Question

The seismic zone factor for Hyderabad city is

• A. 0.36
• B. 0.24
• C. 0.16
• D. 0.10

Hint:

The seismic zone factor \(Z\) represents the expected peak ground acceleration for the maximum considered earthquake in a region.

Answer 1

The Correct Option is D

Step 1: Recall the zone system.
As per IS 1893, India is split into four seismic zones II, III, IV and V.

Step 2: List the zone factors.
Their zone factors \(Z\) are 0.10 for II, 0.16 for III, 0.24 for IV and 0.36 for V.

Step 3: Place Hyderabad.
Hyderabad lies in the relatively stable Deccan region and is put in Seismic Zone II, the lowest risk zone.

Step 4: Pick its factor.
Zone II carries a zone factor of \(Z = 0.10\).

Step 5: Check the options.
Among the values the one matching Zone II is 0.10.

Step 6: Conclude.
The seismic zone factor for Hyderabad is 0.10.
\[ \boxed{0.10} \]
