Start Date

September 28, 2018

Overview

A 7.5-magnitude earthquake and subsequent tsunami occurred just off Sulawesi island in Indonesia on Friday September 28, 2018. The deadly earthquake and tsunami have left at least 844 people dead with fear that the death toll will continue to rise. Dozens of people may be underneath the rubble of one hotel alone, the Roa-Roa in the devastated resort of Palu, Indonesia. The region of Donggala, north of Palu and close to the epicenter of the earthquake is of particular concern. The region comprises nearly 300,000 people.

MODIS near Real-Time Data to Detect Flooding in Indonesia
This map was created from the Moderate Resolution Imaging Spectroradiometer (MODIS) Near Real-Time Global (NRT) Flood Mapping product.  This image shows the 3-day composite flood (new/anomalous) water in red on top of the surface (known/existing) water in yellow. According to several news media outlets, many coastal buildings and streets were already flooded on September 28, 2018, indicating that an initial wave had already hit the coast in Palu, Indonesia.  (Source: The New York Times,...
