Lots of medics and emergency workers are helping people in Indonesia after a large earthquake happened there on Friday.

It was a 7.5-magnitude earthquake. (That is how earthquakes are measured in terms of how bad they are. Seven point five is very big.)

The earthquake also caused a tsunami. That is a massive wave of water. When an earthquake happens on or near a large body of water, it can cause huge waves and flowing water that does a lot of damage. The earthquake in Indonesia was along the coast, near a city called Palu, which is on a bay.

Many people helped those who were affected by the disaster.
