Magnitude is a measure of the amount of energy released during an earthquake. It is frequently described using the Richter scale. To calculate magnitude, the amplitude of waves on a seismogram is measured, correcting for the distance between the recording instrument and the earthquake epicentre. Since magnitude is representative of the earthquake itself, there is only one magnitude per earthquake.

The B.C. Earthquake Immediate Response Plan (IRP) is the first component of a comprehensive provincial plan for earthquake response, and it sets the conditions for the subsequent planning efforts: sustained response and recovery.

Heavy Urban Search and Rescue (HUSAR) provides critical resources and a specially trained taskforce of up to 125 personnel with medical, fire suppression, emergency response, search and rescue, and engineering backgrounds.

British Columbians forced from their homes by fire, floods, earthquakes or other emergencies may receive emergency social services provided through Emergency Management BC’s emergency support for up to 72 hours.

Most earthquake damage is caused by ground shaking. The magnitude or size (energy release) of an earthquake, distance to the earthquake focus or source, focal depth, type of faulting, and type of sub-surface material are important factors in determining the amount of ground shaking that might be produced at a particular site.

An earthquake occurs when rocks break and slip along a fault in the earth. Energy is released during an earthquake in several forms, including as movement along the fault, as heat, and as seismic waves that radiate out from the "source" in all directions and cause the ground to shake, sometimes hundreds of kilometres away.

In British Columbia, the Coroners Act requires that the coroner confirm the identity of the deceased and how, when, where and by what means death occurred for all traumatic and sudden and unexpected deaths. This is the same in a mass disaster.

The Salvation Army in B.C. has a fleet of 14 mobile kitchens capable of feeding thousands of people in an actual disaster.

British Columbia is committed to sustainable forest management. A key element of that are silviculture practices. Effective silviculture practices help control the establishment, growth, composition, quality and harvest of forest vegetation for various forest resource objectives. These include timber harvesting, wildlife, water, recreation, and aesthetic values, or a combination of these objectives and other forest uses.

In these past few weeks, the agricultural sector has been moving forward with great leaps and bounds into the future of farming and organic foods.
