A tsunami in Indonesia crashed into the island of Sulawesi with an enormous wave, forcing terrified onlookers to flee inland to escape the water. Footage from the Indonesia island captured the moment the huge wave struck the coast submerging homes and quickly reaching high buildings. Onlookers can be heard screaming as the water approaches before fleeing away. The screen briefly turns to black before returning to capture footage of the devastated surroundings. The tsunami was sparked by a 7.5 magnitude earthquake that hit the island earlier on Friday.

One person was killed by the earthquake while 10 were reported injured after a powerful quake targeted Indonesia on Friday morning. The US Geological Survey (USGS) said the quake was centered at a depth of six miles approximately 35 miles away from the town of Donggala, in the northeast of the country. The area was hit by a lighter quake earlier in the day, which destroyed some houses, killing one person and injuring at least 10 in Donggala, authorities said. Some people took to Twitter saying they could not contact loved ones. One said: "My family in Palu is unreachable." The earthquake and tsunami have caused havoc with communications on the island as rescue agencies based in the capital Jakarta attempt to coordinate with local authorities.

We advise people to remain in safe areas, stay away from damaged buildings Purwo Nugroho

Sutopo Purwo Nugroho from the National Disaster Mitigation agency warned locals to stay safe and avoid damaged buildings. In a televised interview, Mr Nugroho said: "We advise people to remain in safe areas, stay away from damaged buildings." He also warned the Indonesian Government expects "more damage and more victims" to be recorded in the coming hours. Communications were down and the airport closed, hampering rescue efforts and making it impossible to assess the damage to life and property, officials said. Additional footage from Sulawesi showed hundreds of injured people laying on stretchers waiting to be treated outside of hospital. The USGS has recently updated its seismology report to include the possibility of up to 10,000 people dying. Indonesia straddles the highly volatile Pacific 'Ring of Fire', where many of the world's volcanic eruptions and earthquakes occur.

With a low proability of 10 percent, there is a real possibility of widespread death as a result. USGS has said: "Recent earthquakes in this area have caused secondary hazards such as tsunamis that might have contributed to losses." The first magnitude 6.1 tremor hit 55km north west of Palu, Central Sulawesi at 3.01pm (local time), striking at a depth of 18.1km, according to data from the US Geological Survey (USGS). This was followed by a 5.4 magnitude quake, which struck 77km north east of Palu, just minutes later at 3.03pm (local time). Authorities were initially forced to raise a tsunami warning for the city of 335,000, but has been dropped since. In 2004, another earthquake off the coast of the Indonesian island of Sumatra had sparked a tsunami that killed 226,000 people across 13 countries.
