Given the above summary, write a detailed text in English for it.
If you live in a coastal zone, the occurrence of an earthquake should be immediate cause for alarm and evasive action. If the sea suddenly recedes (draws back), leaving bare sand, this is a major warning sign that there is about to be a sudden surge of water inland. Watch for animals leaving the area or behaving abnormally, such as trying to seek human shelter or grouping together in ways they would not normally do. If the local authorities do have time to issue a warning, take heed. Inform yourself in advance of how the local authorities plan to make warnings so that you do not mistake or ignore the warning when it comes. Share that information with family, friends, neighbors and the community; if the local authorities have pamphlets, a website or other information sources, ask for copies to distribute or request that the local authority fulfills this role.
