Around 15 minutes after the earthquake, the tsunami height estimations are issued in five classes, and JMA uses the upper-limit value for each class in the next warnings (1 m, 3 m, 5 m, 10 m and above 10 m). It is a series of great destructive sea waves that are usually caused by some sort of earthquake activity or underwater disturbance (underwater earthquake, volcanic eruption or landslide). The first information given is based on the earthquakeâs location and magnitude and on a large database of computer simulation, using several tsunamis with earthquakes scenarios in different locations and with different magnitudes. "Sewage testing is used as an early warning system to alert people about (possibly unnoticed) ongoing community transmission," said Yuki Furuse, a Kyoto University professor who wasn't directly involved in the study.
