Why are seismic upgrades taking place in b. c?

The seismic upgrades are taking place in British Columbia because there are several schools in the province that are on high-risk during a high-scale earthquake.

Explanation:

The seismic upgrade is the program that upgrades a structure to make it resistant to earthquakes or any underground activities. It is also known as seismic retrofitting.

The Engineers in British Columbia have examined that several schools in the province are at high-risk during high-scale earthquakes. This would mean that any earthquake with high scale had the possibility of burrying down the school buildings which places the life of those children at more risk.

Thus, the government is preparing for the seismic upgrades in B.C.
