Registering a surface wave magnitude of 7.0, the earthquake originated from a highly active seismic zone.

The volcano lies about 100km mi above a very active seismic zone.

Portions of the pipeline will also cross an active seismic zone that had a 4.3 magnitude earthquake as recently as 2002.

Buildings in seismic zones are often constructed to take into account the oscillating frequencies of expected ground motion.

For this reason, high seismic zones typically only allow fully grouted walls in their building codes.
