The recent Palu earthquake and tsunami that followed will definitely raise the issue of tsunami warnings. The Indonesian official responsible for warnings (BMKG, The Meteorology, Climatology and Geophysics Agency) followed standard operations procedure and ended the tsunami warning. Why? The sensor, 200 km away from the Palu showed only 6 cm wave.
We will learn probably sometimes later, whether the tsunami wave already had passed the sensor at 200 km, or whether it arrived there after the warning was already lifted. Anyway, this incident will help the officials to improve the warning system efficiency.
