Confirmed Threat

When a magnitude 8.8 earthquake off Kamchatka placed all of Hawaiʻi under a tsunami warning on July 29, 2025, Hawaiʻi Pacific University's downtown Honolulu campus — which sits in a coastal tsunami evacuation zone — activated its evacuation procedures. Thousands fled coastal Honolulu and Waikīkī during evening rush hour as sirens sounded. The warning was downgraded and ultimately cancelled with no major damage.

INITIAL ALERTSMS
Approximate reconstruction208 chars
HPU Alert: A Tsunami Warning is in effect for the State of Hawaii. The downtown Honolulu campus is in a tsunami evacuation zone. Move inland or to higher ground now. Do not return until an all-clear is given.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Reconstructed warning. The exact HPU Alert text was not recovered; this paraphrases HPU's published tsunami-evacuation guidance for its downtown campus combined with the statewide warning language. isVerbatimConfirmed is false.
HPU's downtown Honolulu campus is in a low-lying coastal area, so a statewide tsunami warning directly triggers evacuation rather than mere monitoring.
UPDATESMS

HPU Alert: The Tsunami Warning for Hawaii has been downgraded to a Tsunami Advisory. Stay off beaches, piers and harbors. Do not return to the downtown campus or coastal evacuation zones until an all-clear is issued.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Reconstructed downgrade. A tsunami advisory still restricts the shoreline, so this is correctly an update rather than an all-clear.
Wave heights reached about 5 feet in Hilo; Honolulu avoided major impact, consistent with the cautious advisory-stage messaging.
ALL CLEARSMS
Approximate reconstruction184 chars
HPU Alert: The Tsunami Advisory for Hawaii has been cancelled and the all-clear has been given. It is safe to return to the downtown campus and coastal areas. Normal operations resume.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Reconstructed all-clear. This message explicitly lifts the restriction and authorizes return to the downtown campus, distinct from the prior advisory update.
An all-clear for the entire state was reported on July 30, 2025, after wave activity subsided.
Context

Background

The July 29, 2025 magnitude 8.8 Kamchatka earthquake triggered a statewide tsunami warning for Hawaiʻi, sending thousands of coastal Honolulu and Waikīkī residents inland during evening rush hour. Hawaiʻi Pacific University's main academic campus sits in downtown Honolulu near the waterfront, within a mapped tsunami evacuation zone, and HPU's emergency-preparedness materials specifically address tsunami evacuation for that location. The warning held for roughly eight hours before being downgraded to an advisory and cancelled, with waves reaching about 5 feet in Hilo but causing no major damage in Honolulu. University of Hawaiʻi researchers later studied the Waikīkī evacuation as a real-world preparedness test. The case captures how an urban coastal campus must convert a distant earthquake into an immediate evacuate-now directive.
