Final answer:
The building code uses seismic data to determine the probability of an earthquake by analyzing the magnitude and frequency of earthquakes in a particular area.
Step-by-step explanation:
The building code uses seismic data to determine the probability of an earthquake. Seismic data includes information about the magnitude and frequency of earthquakes in a particular area.
By analyzing this data, engineers and scientists can assess the likelihood of an earthquake occurring and design buildings that can withstand the expected ground shaking.
