🌀 Should You Panic-Buy Gas Before a Tsunami? What Maui Residents Need to Know

During our recent tsunami warning on Maui, one of the most striking scenes was the long, snaking lines at gas stations. Drivers rushed to fill up — some topping off tanks, others hoarding gasoline in portable containers. But is this really necessary?

Let’s break down the facts — because panic-buying gas before a tsunami isn’t just unnecessary for most Maui residents — it may even put others at greater risk.

🌊 Most Tsunamis on Maui Are Coastal Events — Not Island-Wide Disasters

Here in Hawaiʻi, most tsunami threats come from distant-source earthquakes — like those from Alaska, Japan, Chile, or Russia. These typically give us 4 to 15 hours of warning time.

The resulting waves usually impact:

• Coastal infrastructure (beach parks, roads near the shoreline)

• Harbors and marinas (like Kahului or Maʻalaea)

• Beachfront homes and businesses

They do not typically affect:

• Fuel depots

• Island-wide power or water

• Inland gas stations or highways like Piʻilani Hwy

⛽ What Happens to Gas Supply During a Tsunami Warning?

Gasoline on Maui is stored in underground tanks and delivered inland by fuel trucks from Kahului Harbor. Most stations — even those near the coast — are built to withstand heavy weather and flooding.

It would take a major, direct tsunami impact on Kahului Harbor — along with road damage — to truly interrupt fuel access for most of the island.

For most tsunami events, fuel remains accessible after the all-clear. The panic lines? Those are driven by fear, not facts.

🚫 Why Panic-Buying Gas Can Actually Be Harmful

If you rush to fill your tank:

• You delay your own evacuation by waiting in long lines.

• You clog evacuation routes for others trying to reach high ground.

• You trigger artificial shortages, leaving essential workers with limited access.

✅ What You Should Do Instead

Here’s a smarter, calmer approach to tsunami preparedness:

• Keep your gas tank above half as a rule during tsunami season.

• If a watch is issued, top off early — before the rush.

• Focus on getting inland or to high ground, not escaping the island.

• Don’t bring extra gas cans — you won’t need them unless it’s a multi-day crisis (which most tsunamis are not).

🧭 Final Thought for Maui Residents

“In a tsunami event, your goal is to reach high ground quickly — not hoard gasoline. Keep your tank above half, skip the panic lines, and help keep the roads clear. Fuel shortages are extremely unlikely unless Maui suffers a major compound disaster. Focus on mobility, not stockpiling.”
