A tsunami had been detected.
“The local hamlet head immediately instructed residents and us students to head up to the hills as soon as the tsunami threat was detected,” said Didan Oktanova Hermawan (Awan), a UMY KKN student representative, recounting the events on the umy.ac.id website.
The UMY KKN students did not rush to the hills immediately; the evacuation prioritized vulnerable groups, who were transported using open-bed trucks.
The students and other residents walked to the safety of the hills, while a number of fishermen quickly took their boats out to sea.
BMKG monitoring stations recorded the tsunami arriving at ten coastal points with varying wave heights.
BMKG’s sea-level observation network (tide gauges) recorded tsunami waves reaching peak heights of 1.61 meters in Reo Manggarai and East Manggarai, 0.94 meters in Maurole Ende, and exceeding 0.5 meters in Bulukumba and Sape Bima. BMKG officially lifted all tsunami early warnings at 07:30 WIB (Western Indonesian Time) or 08:30 WITA (Central Indonesian Time).
