--------------------------------------------------------------------------------

... FINAL TSUNAMI BULLETIN FOR THE INDIAN OCEAN ...

This bulletin applies to areas within and bordering the Indian Ocean.
It is issued in support of the UNESCO/IOC Indian Ocean Tsunami
Warning and Mitigation System (IOTWMS).

1. TSUNAMI SOURCE INFORMATION
IOTWMS-TSP INDONESIA has detected a volcanic eruption with the
following details:

Date            : 25 Oct 2025
Origin Time     : 1400 UTC
Latitude        : 12.92S
Longitude       : 45.72E
Location        : FANI MAORE VOLCANO

2. EVALUATION
Data from sea-level gauges confirmed that a tsunami was generated.

The expected period of significant tsunami waves is now over for all
Threatened Indian Ocean countries, based on IOTWMS-TSP INDONESIA modelling.

Because local conditions can cause a wide variation in tsunami wave
action, CANCELLATION of national warnings and ALL CLEAR determination
must be made by national/state/local authorities. The tsunami warning
status reported by National Tsunami Warning Centres (NTWCs) of
IOTWMS member states for their countries can be found at:   
http://www.incois.gov.in/Incois/tsunami/NTWCFeedbackStatus.jsp

Please be aware that dangerous currents can continue for several
hours after the main tsunami waves have passed.

3. TSUNAMI WAVE OBSERVATIONS
Listed below are maximum wave amplitudes recorded at the specified
locations. Note that wave amplitude is measured relative to normal
sea level; it is NOT the crest-to-trough wave height.
