Mobile phone footage circulating on social media shows a wave of around two metres height hitting the Indonesian island of Palu after the second of two earthquakes rocked Indonesia.
According to reports, an earthquake measuring 7.7 on the Richter scale hit Central Sulawesi shortly after a 6.0-magnitude quake killed one and injured at least 10 people in Donggala, Central Sulawesi, on Friday afternoon.
The earthquake caused a tsunami to hit Palu, which can be seen in this video.
The waters appear to completely overwhelm restaurants on the beach and damage a local mosque next to a busy shopping mall.
No casualty details have emerged from the region yet.
Indonesian disaster agency spokesman Sutopo Purwo Nugroho said a tsunami has hit another city, Donggala, too after the earthquake.
The waters have now receded.
Since you are here
Since you are here, we wanted to ask for your help.
Journalism in Britain is under threat. The government is becoming increasingly authoritarian and our media is run by a handful of billionaires, most of whom reside overseas and all of them have strong political allegiances and financial motivations.
Our mission is to hold the powerful to account. It is vital that free media is allowed to exist to expose hypocrisy, corruption, wrongdoing and abuse of power. But we can't do it without you.
