🌊 Tsunami Preparedness: React Fast, Stay Safe

💡 Fast Facts That Could Save Your Life

  • Tsunamis can arrive minutes after an earthquake, with waves traveling up to 500 mph
  • You may only have 10–30 minutes to evacuate—don’t wait for official alerts if you feel strong shaking
  • Most tsunami deaths occur within the first wavebut later waves can be just as deadly
  • All coastal areas near the ocean, especially after a large offshore or coastal earthquake, are at elevated risk

⚠️ What Makes Tsunamis So Dangerous?

  • Little Warning: Earthquake-triggered tsunamis often strike before alerts can be issued
  • Multiple Waves: Tsunamis arrive in sets—the second or third wave is often larger than the first
  • Inland Flooding: Water can surge miles inland, wiping out roads, bridges, and entire neighborhoods
  • Debris + Current Hazards: Floodwaters often carry cars, wood, metal, sewage, and chemical runoff
  • Post-Tsunami Hazards: Fires, contamination, electrocution, and displacement are common

🌎 Coastal Earthquakes = Immediate Risk

If you are near the ocean and feel a strong or long-lasting earthquake:

  • Do not wait for a tsunami warning
  • Immediately move inland and to higher ground (at least 100 ft elevation or 2 miles inland, if possible)
  • A tsunami may arrive in under 15 minutes

🎒 Essential Tsunami Gear & Go-Bag Checklist

Have these items pre-packed and ready if you live near the coast:

  • Lightweight go-bag stored above ground level
  • High-grip shoes or boots (roads may be slick or covered in debris)
  • Paper maps with marked evacuation routes
  • Headlamp or flashlight (power outages are common)
  • Emergency whistle
  • Portable water filter and snacks
  • N95 mask (for post-disaster air/mold)
  • Copies of ID and medication list in a waterproof pouch
  • Poncho or emergency blanket for warmth and wind protection

🚨 Evacuation or Shelter?

🏃‍♂️ Evacuate Immediately If:

  • You feel a strong or long earthquake (especially near the coast)
  • You hear a tsunami siren, see a rapid water recession, or get an alert
  • You’re located on the coast, harbor, or river connected to the ocean

🏠 Shelter Only If:

  • You're already inland and on elevated, tsunami-safe ground
  • You have no safe evacuation option (in which case, go to the highest possible floor or rooftop)

⏳ How long may you be displaced?
Anywhere from 24 hours to several weeks. Roads, utilities, and infrastructure may take time to restore.

👨‍👩‍👧‍👦 Family Tsunami Safety Tips

  • Practice evacuation routes with your family at least twice a year
  • Designate a high ground rally point and keep it known to all household members
  • Keep a wallet-sized tsunami checklist card in your child’s bag
  • If you're near the beach and feel shaking, don’t wait—run uphill or inland immediately
  • Pets should be part of your evacuation plan (leash, food, ID tags in the go-bag)
