At least 30 people have been killed after a strong tsunami triggered by a magnitude 7.5 earthquake hit a coastal Indonesian city on Friday.
Waves of up to 2m (6.6ft) high swept through Palu on Sulawesi island.
Video on social media shows people screaming and fleeing in panic and a mosque amongst the buildings damaged.
Last month, a series of deadly earthquakes struck the Indonesian island of Lombok, with the biggest, on 5 August, killing more than 460.
Rescue operations have started but a minister said on Friday that communications had been disrupted and that the runway in Palu was damaged.
A photographer for the AFP news agency at the scene reported that scores of people had been killed. It is not clear whether the deaths came in the quake or the resulting tsunami.
The earthquake hit just off central Sulawesi at a depth of 10km (6.2 miles) just before 18:00 (11:00 GMT), the US Geological Survey said.
A tsunami warning was issued, but lifted within the hour.
A Video of the tsunami hitting Palu shows the high waves sweeping away several buildings and then the large tilted mosque in the town, about 80km from the quake’s epicentre.
“The situation is chaotic, people are running on the streets and buildings collapsed. There is a ship washed ashore,” Dwikorita Karnawati, head of Indonesia’s meteorology and geophysics agency.
A 2004 tsunami triggered by an earthquake off the Indonesian island of Sumatra killed 226,000 across the Indian Ocean, including more than 120,000 in Indonesia.
Indonesia is prone to earthquakes because it lies on the Ring of Fire – the line of frequent quakes and volcanic eruptions that circles virtually the entire Pacific rim.
Brett Kavanaugh: Trump’s Supreme Court pick faces FBI inquiry
President Donald Trump has ordered an FBI investigation into sexual misconduct allegations against his nominee for the US Supreme Court.
A Senate committee earlier voted to approve Brett Kavanaugh’s nomination to the top US court.

But a Republican member only backed the move on the understanding that such an inquiry would occur.
As a result, a full Senate vote on Judge Kavanaugh’s confirmation has been delayed for up to a week.
Judge Kavanaugh, an appeal court judge, denies allegations from at least three women.
On Thursday, the committee heard testimony from Christine Blasey Ford, a professor of psychology in California, who says Judge Kavanaugh sexually assaulted her when they were teenagers in the 1980s.
Judge Kavanaugh also testified, angrily rejecting the allegation he had ever assaulted her or anyone else. He accused Democrats of politicising the process and harming his family and good name.
Announcing the move, President Trump said: “I’ve ordered the FBI to conduct a supplemental investigation to update Judge Kavanaugh’s file. As the Senate has requested, this update must be limited in scope and completed in less than one week.”
The inquiry will involve the FBI reopening its previously completed background check on Judge Kavanaugh. This might mean going back to old witnesses – or speaking to new ones.
Friday saw Republicans on the Senate Judiciary Committee throw out Democrat attempts to subpoena Mark Judge, a friend of Judge Kavanaugh who Dr Ford said had witnessed the assault on her 36 years ago.
Mr. Judge had told the committee in a written statement that he did not recall any such incident.
Mr. Judge’s lawyer Barbara Van Gelder said: “If the FBI or any law enforcement agency requests Mr. Judge’s co-operation, he will answer any and all questions posed to him.”
Responding to President Trump’s statement, Judge Kavanaugh said “I’ve done everything they have requested and will continue to co-operate”.
