## Questions to Ask the User First

1. **Location:** What seismic zone are you in? (e.g., California, Pacific Northwest, New Madrid, Alaska)
2. **Building type:** Wood frame, unreinforced masonry, concrete, steel frame, mobile home?
3. **Building age:** When was it built? (pre-1970 is higher risk in many regions)
4. **Household:** How many people? Children, elderly, people with disabilities?
5. **Current preparedness:** Do you have supplies, a plan, or structural improvements?
6. **Pets:** Types and how many?
7. **Workplace:** Do you need workplace preparedness guidance too?

## Understanding Earthquake Risk

### Magnitude and Intensity

```
Magnitude (Richter/Moment Magnitude):
  Energy released at the source (objective measurement)

  < 4.0: Generally not felt or minor
  4.0-4.9: Light -- felt by many, rarely damages
  5.0-5.9: Moderate -- damage to vulnerable buildings
  6.0-6.9: Strong -- destructive in populated areas
  7.0-7.9: Major -- serious damage over large areas
  8.0+: Great -- severe destruction, regional impact

Intensity (Modified Mercalli Scale):
  What you experience at your location (varies by distance, soil, building)

  I-III: Not felt to weak
  IV-V: Light to moderate (felt, minor damage)
  VI-VII: Strong to very strong (moderate damage)
  VIII-IX: Severe to violent (heavy damage)
  X+: Extreme (total destruction of some structures)

Key understanding:
  - A magnitude 7 is NOT "a little worse" than magnitude 6
  - Each whole number = 32x more energy released
  - Damage depends on: magnitude, distance, soil type, building quality
  - Soft soil amplifies shaking (liquefaction risk)
```

## Before an Earthquake

### Home Hazard Assessment

```
Room-by-room safety check:

Living Areas:
  [ ] Heavy furniture secured to wall studs (bookcases, wardrobes)
  [ ] TV mounted or secured with anti-tip straps
  [ ] Mirrors and pictures secured with closed hooks (not open nails)
  [ ] Heavy objects on lower shelves, not upper
  [ ] Area rugs secured (prevent sliding)

Kitchen:
  [ ] Cabinet latches installed (prevent dishes falling out)
  [ ] Water heater strapped to wall (two straps minimum)
  [ ] Heavy appliances on non-slip mats
  [ ] Hazardous materials (cleaning products) in latched low cabinets

Bedroom:
  [ ] Nothing heavy above or beside the bed
  [ ] Flashlight and shoes within reach of bed
  [ ] Sturdy shoes to protect from broken glass
  [ ] Heavy dresser or wardrobe secured to wall

Utility:
  [ ] Know where gas shut-off valve is (and have wrench nearby)
  [ ] Know where water shut-off is
  [ ] Know where electrical panel is
  [ ] Flexible gas connections on appliances (reduces leak risk)

Structure:
  [ ] Foundation bolted to sill plate (pre-1970 homes often not)
  [ ] Cripple wall bracing in crawl space (if applicable)
  [ ] Chimney condition assessed (unreinforced chimneys are top failure)
  [ ] No unreinforced masonry walls
```

### Structural Retrofitting (By Priority)

```
Priority 1 (highest impact):
  Foundation bolting: Secure house frame to concrete foundation
  Cost: $3,000-7,000
  Why: Prevents house from sliding off foundation

  Cripple wall bracing: Strengthen short walls between foundation and floor
  Cost: $3,000-5,000
  Why: Cripple walls are the most common failure point in wood-frame homes

Priority 2:
  Water heater strapping: Strap to wall studs with metal straps
  Cost: $20-100 (DIY) or $200-400 (professional)
  Why: Prevents tipping, gas line break, fire, water damage

  Chimney assessment: Unreinforced masonry chimneys often fail
  Cost: $500-5,000 depending on fix needed
  Why: Falling chimney bricks are a major injury source

Priority 3:
  Soft-story retrofit: For multi-story buildings with weak ground floor
  Cost: $50,000-200,000 (building-wide)
  Why: Ground floor parking/commercial can collapse in strong shaking

Check for incentives:
  - California Earthquake Authority (CEA) Brace + Bolt program
  - FEMA Hazard Mitigation Grant Program
  - State/local retrofit incentive programs
```

## During an Earthquake

### Drop, Cover, and Hold On

```
WHEN SHAKING STARTS:

INDOOR:
  1. DROP to hands and knees (prevents falling)
  2. COVER head and neck under sturdy furniture (desk, table)
     If no furniture: against interior wall, cover head with arms
  3. HOLD ON to the furniture and be prepared to move with it

  DO NOT:
  - Run outside (falling debris is the danger)
  - Stand in a doorway (not safer than under a table in modern buildings)
  - Try to go to a different room (you'll fall)
  - Use elevators

OUTDOOR:
  - Move away from buildings, trees, power lines, streetlights
  - Drop to the ground in an open area
  - Cover head and neck with arms

IN A VEHICLE:
  - Pull over to clear spot (away from bridges, overpasses, buildings)
  - Stop, set parking brake
  - Stay in the vehicle (it provides protection)
  - When shaking stops, proceed cautiously (watch for road damage)

IN BED:
  - Stay in bed
  - Cover head with pillow
  - Only move if there is a heavy object above you that could fall

Note: Shaking typically lasts 10-30 seconds for moderate quakes.
Large earthquakes can shake for 1-3 minutes. It will feel longer
than it actually is.

## After an Earthquake

### Immediate Actions (First Minutes)

```
  [ ] Check yourself and others for injuries
  [ ] If trapped: tap on pipe or wall (rescuers listen for this)
      Use whistle if available. Conserve energy -- don't shout.
  [ ] Put on sturdy shoes (broken glass everywhere)
  [ ] Check for hazards:
      - Gas smell? Open windows, leave building, call gas company
        DO NOT light matches, operate electrical switches, or use phone near leak
      - Electrical damage? Turn off at breaker panel
      - Water leak? Turn off at main shut-off
      - Structural cracks? If significant, evacuate

  [ ] Check on neighbors (especially elderly, disabled)
  [ ] Use text messaging (networks handle texts better than calls)
  [ ] Contact out-of-area person to relay status
  [ ] Turn on battery radio for official information
```

### Aftershock Preparedness

```
After a major earthquake, expect aftershocks:
  - Can be nearly as strong as the main quake
  - Most common in first hours/days
  - Can continue for weeks or months
  - Each aftershock can cause additional damage to weakened structures

Aftershock protocol:
  - Drop, Cover, Hold On for every aftershock
  - Stay out of damaged buildings
  - Be ready for disrupted utilities for days to weeks
  - If building was marginal in main quake, aftershock may collapse it

Aftershock probability (rough guide):
  After a M7 earthquake:
  - ~10% chance of a larger earthquake in the next week
  - ~95% chance of M5+ aftershocks
  - Aftershocks gradually decrease in frequency
```

## Family Communication Plan

```
BEFORE an earthquake:

1. Designate an out-of-area contact
   Someone 200+ miles away who everyone calls/texts
   Local lines will be overwhelmed; long-distance often works

2. Establish meeting points:
   Near home: Front yard, neighbor's driveway
   Away from home: A specific park, school, or landmark
   Out of area: Relative's home (if evacuation needed)

3. Everyone carries:
   - Printed contact list (phones may die)
   - Family meeting point addresses
   - Medical information (allergies, medications)
   - Cash

4. Practice:
   - Participate in annual ShakeOut drill (October)
   - Practice Drop, Cover, Hold On at home
   - Practice shutting off gas and water
   - Everyone knows where supplies are stored

DURING/AFTER:
  - Text, don't call (texts use less bandwidth)
  - Try: "I'm OK" feature on social media
  - Check Red Cross Safe and Well website
  - If separated: go to pre-arranged meeting point
```
