7.5
Step-by-step explanation:
The tsunami in Sulawesi occurred in September 2018. It was as most earthquakes that trigger tsunamis, as the majority of the tsunamis are triggered by earthquakes that occur in the bellow the ocean, but this one occurred on land. The earthquake was preceded with multiple foreshocks, and when the main one came it was with a magnitude of 7.5 Richter. The earthquake occurred in the mountainous part of the peninsula. Initially the officials rang the tsunami alarm, but after half an hour called it off. That was a big mistake. Even though the tsunami was only on a local scale, it occurred, and it wiped out the coastal area. Around 4,340 people have lost their lives, with thousands of houses and infrastructure being destroyed. This is made it the most devastating earthquake in 2018, and the deadliest earthquake in Indonesia since 2006.
