Singapore and Malaysia's Sabah state are observing a day of mourning for those killed in the Mt Kinabalu quake.
Sixteen people are confirmed dead after the magnitude 6.0 quake, which hit the mountain in Sabah on Friday.
Among the dead were six Singaporean children on a school trip, along with their teacher and their Singaporean adventure guide. The children were from Tanjong Katong Primary School.
In Singapore, flags are at half-mast and a minute's silence was observed at venues for the Southeast Asian Games, which the city-state is hosting.
At the weekend, Sabah Deputy Chief Minister Joseph Pairin Kitingan linked the earthquake to a group of 10 foreigners who had earlier stripped naked on Mt Kinabalu.
He said the tragedy was a "confirmation" that they had showed "disrespect" to the mountain.
"It is a sacred mountain and you cannot take it lightly," he told reporters.
Authorities have identified some of the tourists and ordered border officials to be on high alert if they tried to leave Sabah.
The Ministry of Foreign Affairs and Trade said local authorities reported a New Zealand climber made their way down the mountain safely after the quake in Sabah.
