    2018 Indonesia Earthquake/Tsunami

    On September 28, 2018, a 7.5 magnitude earthquake struck the island of Sulawesi near its central province, Palu. The earthquake cut the power off for many, which is why people didn't receive a warning about the tsunami which quickly followed. 

    The tsunami had waves up to 10 feet high as it tore through Palu. In the three days after the disaster, officials confirmed 844 dead, and they believed they would find more underneath the rubble of collapsed buildings and homes. 

    Roughly 2.4 million people were affected by the quake and the tsunami. Some people resorted to looting for necessities like fuel and water. Over 1,000 inmates fled from five prisons, and officials demanded that inmates return within the week.
