I want to know the answer to the following question:
How many estimated active faults does Houston have?
All the background I'm provided with is that "The Houston area has over 150 active faults (estimated to be 300 active faults) with an aggregate length of up to 310 miles (500 km), including the Long Point–Eureka Heights fault system which runs through the center of the city.". Is that enough to answer the question?
