The recent earthquakes off the northern coast of Vancouver Island are a reminder that B.C. is a hotbed for seismic activity.

Thursday's 5.8 magnitude quake was the strongest of more than 100 recorded since the beginning of the week, according to the Geological Survey of Canada.

Even though offshore quakes wouldn't typically pose a threat to residents until they reached a magnitude of seven or higher, experts say British Columbians should always be ready for earthquakes and tsunamis.

Michael Smith from Vancouver's Fire and Rescue Services says the most important way to be earthquake ready is having an established plan, including having enough critical supplies for yourself and your family for at least three days - or "the three-day rule."

Here's what you need to know to prepare yourself and your family for a major earthquake:

Emergency Preparedness Plan (from Vancouver's Fire and Rescue Services):

  • Stock up on at least a three-day supply of water, food and medical supplies for all family members. 
  • Exit plan: Decide where and when to reunite your family after an emergency.
  • Phone a friend: Choose a person at least 300 kilometres away from where you live to contact if your family becomes separated. Long distance phone service is often restored faster than local lines.
  • Be prepared: Practice emergency exit plans with your family every six months.
  • Know the safest place in each room because it will be difficult to move from room to room.
  • Locate shutoff valves for electricity, water and gas. Know how to use them.
  • Make copies of vital records and keep them in another city/province.
  • Take photos and/or videos of your valuables for insurance purposes.
  • Keep an extra set of glasses and car keys on hand.
  • Keep extra cash and change. In case of an emergency, it is unlikely ATM's will work.
  • Keep an emergency kit. Check and replace items every six months.

Tips if you are at home during a quake:

  • Keep your hallway clear. It is usually one of the safest places to be in an earthquake.
  • Stay away from kitchens and garages, which tend to be the most dangerous places because of the many items that are stored there.
  • Stay away from heavy furniture, appliances, glass panes, shelves holding objects, and large masonry - like fireplaces.

Basic emergency kit supplies:

  • Four litres of water per person per day.
  • Non-perishable food.
  • First-aid supplies and training.
  • Pet supplies.
  • Battery-operated radio.
  • Flashlights with extra batteries.
  • Toiletries.
  • Clothing.
  • Blankets.
  • Medicine.
