Earthquake Preparedness for BC Prefab Cabins

## Earthquake Safety for BC Cabins

British Columbia sits in one of North America's most seismically active regions. Here's how our cabins are designed for safety and how you can prepare.

### BC Seismic Risk

**Understanding the Risk**:
- BC's coast sits on the Cascadia Subduction Zone
- Potential for magnitude 9.0+ megathrust earthquake
- Active fault systems throughout the region
- Interior BC also has significant seismic activity

**Seismic Zones**:
Most of BC falls into Seismic Zone 4 or higher, requiring substantial structural engineering for safety.

### Prefab Seismic Advantages

**Factory-Controlled Construction**:
- Consistent quality and connections
- No weather-degraded materials
- Precision assembly techniques
- Better quality control than site-built

**Engineered Connections**:
- Specifically designed for lateral forces
- Hold-down anchors at key points
- Metal connectors throughout structure
- Continuous load path to foundation

**Structural Integrity**:
- Single-unit construction (no seams in structure)
- Integrated floor, wall, roof systems
- Lightweight relative to site-built (less inertia)
- Tested construction methods

### Avanta Homes Seismic Features

**Foundation Connection**:
- Continuous sill plate anchoring
- Hold-downs at critical points
- Engineered for uplift and lateral forces
- Compatible with helical pile, concrete, or block foundations

### Preparing Your Cabin

**Secure Contents**:
- Anchor tall furniture to walls
- Secure water heater with straps
- Install latches on cabinet doors
- Secure heavy items on high shelves
- Strap propane tanks and cylinders

**Utilities**:
- Know location of gas/propane shutoff
- Know main water shutoff
- Know electrical panel location
- Consider automatic gas shutoff valve
- Flexible connections for gas appliances

**Emergency Supplies**:
- 72-hour supply of water (4L/person/day)
- Non-perishable food
- First aid kit
- Flashlights and batteries
- Battery-powered radio
- Whistle (for signaling)
- Dust masks
- Fire extinguisher
- Basic tools
- Cash (small bills)
- Important documents (copies)

**Communication Plan**:
- Family meeting point (near cabin)
- Out-of-area contact person
- Everyone knows the plan
- Regular practice drills

### During an Earthquake

**If Inside**:
- DROP to hands and knees
- Take COVER under sturdy furniture
- HOLD ON until shaking stops
- Stay away from windows and heavy furniture
- Don't run outside during shaking

**If Outside**:
- Move away from buildings, trees, power lines
- Drop and cover if possible
- Stay in open area until shaking stops

**If in Bed**:
- Stay in bed, protect head with pillow
- Don't run to doorway (outdated advice)
- Stay away from windows

### After an Earthquake

**Immediate Actions**:
- Check for injuries
- Check for structural damage
- Check for gas leaks (smell, hissing)
- Check for electrical damage
- Check water and sewer lines
- Be prepared for aftershocks

**Evacuation Decisions**:
- Leave if building is clearly damaged
- Leave if you smell gas
- Leave if there's a tsunami warning (coastal areas)
- Stay if building is safe

**Inspection**:
- Document any damage with photos
- Contact insurance company
- Have structure professionally inspected if any concern
- Report damage to local emergency management

### Insurance Considerations

**Earthquake Coverage**:
- Typically not included in standard policies
- Separate rider or policy required
- Higher deductibles common (5-15% of coverage)
- Strongly recommended in BC

**Coverage Types**:
- Dwelling coverage
- Contents coverage
- Additional living expenses
- Debris removal
