First Aid Skills Everyone Should Know for Earthquakes: Complete Guide 2026

Earthquakes cause injuries that normal daily life doesn't prepare people for: crushing trauma from collapsed structures, massive bleeding from shattered glass and metal, compound fractures from falling debris, shock from multiple injuries, and situations where professional medical help is hours or days away. After the 1994 Northridge earthquake, hospitals were overwhelmed with 1,600 injured patients within the first 24 hours. After the 2010 Haiti earthquake, medical systems collapsed entirely and bystander first aid was the only care available for hundreds of thousands of victims.

Standard first aid training focused on minor cuts, sprains, and choking doesn't adequately prepare people for earthquake trauma scenarios. Earthquake first aid requires knowledge of severe bleeding control, fracture stabilization, crush syndrome recognition, mass casualty triage, and the judgment to know when attempting rescue causes more harm than waiting for professionals. These skills save lives when professional medical care is delayed, overwhelmed, or completely unavailable.

This comprehensive guide covers the critical first aid skills everyone in earthquake-prone regions should know: immediate life threats and how to address them, severe bleeding control techniques, fracture and spinal injury management, crush syndrome and compartment syndrome, shock recognition and treatment, when to move injured people versus when to wait, basic triage for multiple casualties, and what supplies to stockpile for earthquake medical scenarios.

Understanding Earthquake-Specific Injuries

Most Common Earthquake Injuries

Earthquake injuries differ significantly from typical accidents:

Blunt Force Trauma:

• Caused by falling debris, toppling furniture, structural collapse
• Can affect head, chest, abdomen, limbs
• May cause internal bleeding without visible wounds
• High risk of fractures and crush injuries

Lacerations and Puncture Wounds:

• Shattered glass causes deep cuts
• Sharp metal edges from damaged structures
• Exposed nails, rebar, building materials
• High contamination risk from debris

Fractures:

• Broken bones from falls, crushing, or impact
• Open fractures where bone punctures skin
• Spinal fractures from structural collapse
• Multiple simultaneous fractures common

Crush Injuries and Crush Syndrome:

• Prolonged compression of limbs or body parts
• Toxic buildup in compressed tissue
• Life-threatening when pressure released
• Requires specific medical management

Head and Spinal Injuries:

• Concussions from falling objects
• Skull fractures
• Traumatic brain injuries
• Spinal cord damage from structural collapse

The ABC Priority System

When encountering injured people, always assess in this order:

A - Airway:

• Is the airway open and clear?
• Can the person breathe?
• Is there obstruction (blood, debris, vomit)?
• Priority: Clear airway immediately or person dies in minutes

B - Breathing:

• Is the person breathing?
• Is breathing adequate (rate, depth)?
• Are there chest injuries affecting breathing?
• Priority: Restore breathing or person dies in minutes

C - Circulation:

• Is there severe bleeding?
• Is heart beating?
• Is person in shock?
• Priority: Stop severe bleeding or person dies in minutes to hours

Everything Else Comes After ABC:

• Fractures, burns, minor wounds wait until ABCs secured
• A person with broken leg but breathing/circulating will survive
• A person bleeding out will die regardless of other injuries treated

Severe Bleeding Control

Uncontrolled bleeding kills faster than almost any other injury. Arterial bleeding can cause death in 3-5 minutes.

Recognizing Severe Bleeding

Arterial Bleeding (Most Dangerous):

• Bright red blood
• Spurting or pulsing with heartbeat
• High volume, rapid flow
• Quickly soaks through clothing
• Life-threatening within minutes

Venous Bleeding (Serious but Less Urgent):

• Dark red blood
• Steady flow without spurting
• Moderate to high volume
• Life-threatening within 10-30 minutes if severe

Capillary Bleeding (Minor):

• Oozing blood
• Slow flow
• Low volume
• Not immediately life-threatening

Direct Pressure (First Response)

Immediate Action for Severe Bleeding:

1. Expose the wound—remove or cut away clothing to see injury clearly
2. Apply direct pressure—use clean cloth, gauze, or bare hands if nothing else available
3. Press HARD—use significant force, this will hurt but saves life
4. Hold pressure for 3-5 minutes minimum—don't lift to "check" if bleeding stopped
5. Add more dressings if blood soaks through—don't remove blood-soaked dressings, just add more on top
6. Elevate injured limb above heart level if possible—reduces blood flow to area

If Direct Pressure Doesn't Stop Bleeding:

• Apply MORE pressure—you're not pressing hard enough
• Ensure you're applying pressure directly over wound, not adjacent tissue
• If limb injury, consider tourniquet (see below)
• Consider wound packing for deep wounds (see below)

Tourniquets (Life-Saving for Limb Injuries)

When to Use a Tourniquet:

• Severe arterial bleeding from arm or leg that direct pressure doesn't stop
• Multiple casualties and you need to move to next victim
• Amputation or near-amputation of limb
• Bleeding from area impossible to apply direct pressure (armpit, groin)
• Your safety requires leaving victim before bleeding controlled

How to Apply Commercial Tourniquet (CAT, SOFT-T):

1. Place 2-3 inches above wound—never place directly on wound, never place on joint
2. Pull tight around limb—secure velcro or clip
3. Twist windlass rod—keep twisting until bleeding stops completely
4. Secure windlass—lock in place so it doesn't unwind
5. Note the time—write time of application on tourniquet with marker if available
6. Do NOT remove tourniquet—only medical professionals should remove, removal can cause shock and death

Improvised Tourniquet (If No Commercial Available):

1. Use wide, strong material—belt, torn shirt folded into 2-3 inch wide band, never rope or wire (too narrow, damages tissue)
2. Wrap around limb 2-3 inches above wound
3. Tie knot, place stick on knot, tie another knot over stick
4. Twist stick—keep twisting until bleeding stops
5. Secure stick—tie or tape in place
6. Note time

Tourniquet Myths Debunked:

• MYTH: Tourniquets cause automatic amputation—FALSE. Military data shows tourniquets can stay on 2-3 hours with no permanent damage
• MYTH: Should only use tourniquets as absolute last resort—FALSE. Use whenever limb bleeding not controlled by direct pressure
• MYTH: Must loosen tourniquet every 20 minutes—FALSE. Once applied, NEVER remove or loosen until medical facility
• MYTH: Tourniquets are too dangerous for civilians—FALSE. Proper tourniquet application saves lives, studies show benefit far outweighs risk

Wound Packing (For Deep Wounds)

When to Pack a Wound:

• Deep wound (knife-like puncture, impalement injury after object removed)
• Wound in area where tourniquet can't be applied (neck, shoulder, groin, armpit)
• Direct pressure alone not controlling bleeding

How to Pack a Wound:

1. Use sterile gauze if available—hemostatic gauze (QuikClot, Celox) best, plain gauze acceptable, clean cloth last resort
2. Stuff gauze directly into wound—push deep, fill wound cavity completely
3. Pack tightly—use significant force, this stops bleeding through compression
4. Keep packing until wound full—may need entire roll of gauze for deep wound
5. Apply direct pressure over packed wound for 3 minutes
6. Bandage over packing—secure with wrap bandage

Fracture Management

Recognizing Fractures

Definite Signs of Fracture:

• Bone visibly broken or protruding through skin
• Limb at unnatural angle
• Bone ends grating against each other (crepitus)
• Heard or felt bone break during injury

Probable Signs of Fracture:

• Severe pain at injury site
• Swelling and bruising
• Inability to move or bear weight
• Deformity or abnormal appearance
• Tenderness when touched

When in Doubt, Treat as Fracture:

• Better to immobilize non-fracture than fail to immobilize fracture
• Movement of fractured bone causes severe pain, tissue damage, bleeding
• Improper movement can convert closed fracture to open fracture

Closed Fractures (Bone Broken, Skin Intact)

Management Steps:

1. Do NOT try to realign bone—this causes extreme pain and can damage nerves/blood vessels
2. Immobilize in position found—splint supports limb in current position
3. Check circulation below injury—feel for pulse, check skin color and temperature, ask if they feel numbness/tingling
4. Apply splint—immobilize joint above and below fracture
5. Recheck circulation after splinting—if pulse lost or limb becomes cold/blue, splint too tight
6. Elevate if possible—reduces swelling
7. Apply ice if available—reduces pain and swelling, don't apply directly to skin

Splinting Principles:

• Immobilize joint above and below fracture—broken forearm requires immobilizing wrist AND elbow
• Pad splint—cloth between splint and skin prevents pressure sores
• Secure splint—ties above and below fracture, not directly over break
• Don't tie too tight—should fit snugly but not cut off circulation

Improvised Splint Materials:

• Rigid: boards, rolled newspaper/magazine, cardboard, straight tree branches, umbrellas, canes
• Padding: towels, clothing, blankets
• Ties: belts, torn sheets, shoelaces, rope, duct tape
• Slings: triangular bandage, torn sheet, belt

Open Fractures (Bone Protruding Through Skin)

CRITICAL: Open fractures are medical emergencies due to massive infection risk and severe bleeding.

Management Steps:

1. Control bleeding first—direct pressure around (not on) protruding bone
2. Do NOT push bone back into wound—extreme infection risk
3. Cover wound with sterile dressing—use clean cloth if sterile unavailable
4. Build padding around protruding bone—doughnut bandage supports and protects bone
5. Splint as for closed fracture—immobilize in position found
6. Seek professional medical care URGENTLY—open fractures require surgical cleaning and antibiotics within hours to prevent life-threatening infection

Spinal Injury Management

When to Suspect Spinal Injury

Spinal injuries can cause permanent paralysis or death if handled improperly. Always suspect spinal injury if:

• Person fell from height (more than their own height)
• Person struck by falling debris on head, neck, or back
• Person found unconscious (assume spinal injury until proven otherwise)
• Vehicle-related injury
• Diving injury or head-first impact
• Severe blunt trauma to torso

Signs of Possible Spinal Injury:

• Neck or back pain
• Numbness or tingling in extremities
• Weakness or inability to move arms or legs
• Loss of bowel or bladder control
• Unconsciousness
• Difficulty breathing
• Odd positioning of head or neck

Spinal Injury Protocol

If you suspect spinal injury:

1. Do NOT move person unless IMMEDIATE life threat—fire, building collapse, dangerous location
2. Stabilize head and neck—hold head still in position found, support on both sides with hands
3. Tell person not to move—explain they may have spinal injury and must remain still
4. If alone, stay with victim and call for help—don't leave to get help unless no other option
5. If must move due to immediate danger:
   • Support entire spine as single unit
   • Requires minimum 3-4 people to move safely
   • Keep head, neck, and back in straight line
   • Move as if person is rigid board

Crush Syndrome and Compartment Syndrome

Understanding Crush Syndrome

Crush syndrome occurs when body parts are compressed for extended periods (typically 1+ hours). When pressure released, toxic buildup from crushed tissue enters bloodstream and can cause kidney failure, cardiac arrest, and death.

Mechanism:

• Prolonged compression damages muscle tissue
• Damaged tissue releases myoglobin, potassium, phosphorus, acids
• While compressed, toxins trapped in compressed area
• When compression released, toxins flood into circulation
• High potassium can stop heart
• Myoglobin clogs kidneys causing failure

Crush Syndrome Management

CRITICAL RULE: If someone trapped more than 1 hour and you don't have IV fluids and advanced medical training, DO NOT REMOVE CRUSHING OBJECT. Wait for professional rescue.

Why This Rule Exists:

• Person may be stable while crushed
• Removing pressure without medical preparation can kill within minutes
• Professional rescuers will start IV fluids BEFORE releasing pressure to dilute toxins
• Hospitals can provide emergency dialysis if needed

If Person Trapped Less Than 1 Hour:

• Safer to remove crushing object (toxin buildup minimal)
• After removing pressure, monitor closely for shock
• Transport to hospital as soon as possible
• Inform medical providers how long person was crushed

If You Must Remove Crushing Object Despite Long Entrapment (Life Threat):

1. Apply tourniquet to crushed limb BEFORE removing crushing object if possible
2. Have someone ready to perform CPR—cardiac arrest possible
3. Remove crushing object
4. Monitor closely for cardiac arrest, provide CPR if needed
5. Immediate transport to hospital critical

Compartment Syndrome

Compartment syndrome is pressure buildup within muscle compartments that cuts off blood flow. Can develop hours after injury.

Signs of Compartment Syndrome:

• The "5 P's":
  • Pain: Severe, out of proportion to injury, worsening over time
  • Pressure: Limb feels tight, swollen, hard
  • Pallor: Limb pale or bluish
  • Paresthesia: Tingling, numbness, "pins and needles"
  • Paralysis: Inability to move fingers/toes (late sign)

Management:

• Remove all tight bandages, splints, jewelry
• Elevate limb to heart level (not above—reduces blood flow)
• Do NOT apply ice (worsens blood flow)
• Seek emergency surgical care—compartment syndrome requires surgical release of pressure within hours to save limb

Shock Recognition and Treatment

Understanding Shock

Shock is circulatory system failure—inadequate blood flow to organs. Can develop from severe bleeding, trauma, pain, fear, or other injuries. Untreated shock leads to organ failure and death.

Types of Shock in Earthquakes:

• Hypovolemic shock: Blood or fluid loss (most common)
• Cardiogenic shock: Heart can't pump effectively
• Neurogenic shock: Spinal injury disrupts blood flow regulation
• Psychogenic shock: Extreme emotional stress causes fainting

Recognizing Shock

Early Signs:

• Rapid pulse (over 100 beats per minute)
• Rapid breathing (over 20 breaths per minute)
• Pale, cool, clammy skin
• Weakness, dizziness
• Anxiety, restlessness
• Thirst

Late Signs (Medical Emergency):

• Confusion, altered mental status
• Weak or absent pulse
• Gasping or labored breathing
• Blue lips and fingernails
• Unconsciousness

Shock Treatment

Management Steps:

1. Treat underlying cause—stop bleeding, stabilize injuries
2. Lay person flat on back—unless head/chest injury or difficulty breathing
3. Elevate legs 12 inches—helps return blood to core (skip if leg fractures or spinal injury suspected)
4. Keep warm—cover with blanket, prevent heat loss to ground
5. Do NOT give food or water—person may need surgery, anything by mouth increases aspiration risk
6. Reassure and calm—emotional support reduces anxiety-driven shock worsening
7. Monitor constantly—check pulse, breathing, consciousness every few minutes
8. Seek professional medical care urgently

When to Move Injured People

Move Immediately (Immediate Danger)

Move person immediately if:

• Fire or smoke
• Building actively collapsing
• Gas leak with explosion risk
• Rising water/flooding
• Active roadway with traffic
• Aftershock causing ongoing structural failure

Emergency Moves (When Scene Unsafe):

• Clothes drag: Grab shirt/jacket behind head, drag backward protecting head and neck
• Blanket drag: Roll person onto blanket, drag blanket
• Arm drag: From behind, reach under armpits, grab one forearm, drag backward
• Two-person carry: Each person supports under arms and knees, move together

DO NOT Move (Wait for Professional Help)

Do NOT move person if:

• Suspected spinal injury (unless immediate danger)
• Crush injury where person trapped more than 1 hour
• Multiple severe injuries
• Impaled object in body
• Severe bleeding not yet controlled
• Person in shock and no immediate danger
• Moving would cause severe pain or further injury

Wait for Professional Rescuers Who Have:

• Spinal immobilization equipment
• Lifting/extrication tools
• IV fluids for crush syndrome
• Trained personnel for complex moves
• Oxygen and advanced airway equipment

Mass Casualty Triage

When multiple people injured and limited resources, triage determines treatment order. This is emotionally difficult but mathematically necessary to save maximum lives.

START Triage System (Simple Triage And Rapid Treatment)

Takes 60 seconds per victim to categorize:

Step 1: Can person walk?

• YES: Tag GREEN (Minor) → treat last
• NO: Continue to Step 2

Step 2: Is person breathing?

• NO: Position airway (head tilt-chin lift)
• Still not breathing after airway positioned: Tag BLACK (Deceased/Expectant) → provide comfort care only
• Breathing after airway positioned: Continue to Step 3
• YES: Continue to Step 3

Step 3: Breathing rate over 30 per minute?

• YES: Tag RED (Immediate) → treat first
• NO: Continue to Step 4

Step 4: Check circulation - can they follow simple commands?

• NO (altered mental status): Tag RED (Immediate) → treat first
• YES: Tag YELLOW (Delayed) → treat second

Triage Categories:

• RED (Immediate): Life-threatening but survivable with immediate treatment (severe bleeding, airway compromise, respiratory distress, shock)
• YELLOW (Delayed): Serious injuries but can wait hours (fractures, moderate bleeding, burns)
• GREEN (Minor): Walking wounded, minor injuries (cuts, bruises, sprains)
• BLACK (Expectant/Deceased): Dead or injuries incompatible with survival given available resources (no breathing despite airway positioned, massive traumatic injuries)

Conclusion: Preparedness Saves Lives

After major earthquakes, professional medical help is overwhelmed, delayed, or completely unavailable. The difference between life and death often depends on what bystanders know and can do in the first critical minutes and hours. A person bleeding from severed artery has 3-5 minutes before death. Professional help may be 3-5 hours away or longer. Knowing how to apply a tourniquet transforms that person's prognosis from certain death to likely survival.

First aid skills aren't just for helping strangers—they're for protecting your family when you're the only medical help available. The skills in this guide—bleeding control, fracture stabilization, shock management, appropriate movement decisions—are teachable, learnable, and lifesaving. They don't require medical school or years of training. They require a day or two of focused learning and periodic practice.

Take a Stop the Bleed course this month (free, 1 hour). Take a First Aid/CPR course this quarter ($70-110, 4-6 hours). Build a trauma-focused first aid kit ($200-400). Practice with your supplies. Review these skills quarterly. When the earthquake strikes and someone you love is bleeding or broken, you'll have the knowledge and tools to help rather than helplessly watching.

Learn first aid now. Practice these skills regularly. When seconds matter and help is hours away, you'll be ready.
