I witnessed how devastating the earthquake shook Aceh in 2004. At that time, I was in the yard of an office across the street in front of the Aceh Governor's Office in Banda Aceh. I see some of the roof of the Governor's Office building collapsed due to the earthquake.

Shortly afterwards, the tsunami waves devastated Banda Aceh, leaving so many people dead. I am very grateful to have managed to escape to the office building in front of Aceh Governor's Office.

After the incident, aftershocks have repeatedly shook Aceh. Even until 2018 there is still an earthquake in this province.

The information I read in a number of media, according to researchers from the Center for Tsunami and Disaster Mitigation Studies (TDMRC) of Syiah Kuala University (Unsyiah) Banda Aceh, in the southern part of Sumatra Island there is a subduction plate zone subduction, the Indo-Australian plate goes under the Eurasian plate. In addition, the Indo-Australian plate tilted, in the middle of Sumatra formed Sumatra fault from the bay of Semangko to Aceh. That is why the island of Sumatra is rich in earthquakes.

I agree with the one written by @kharrazi, that we all should always be wary of the earthquake. If we want to learn from local wisdom, Acehnese ancestors actually have given an example. They built houses on stilts using wood, so the houses of the Acehnese in the past remained strong, did not collapse despite the earthquake.

Thanks @kharrazi has written an article containing science that is very useful for many people about the earthquake, hopefully in the future everyone is more responsive to natural disasters, including earthquake disaster.
