ABSTRACTRusunawa Purus, Padang City is one of the buildings that is prone to earthquakes and tsunamis because of its location close to the coast, increasing the vulnerability of the flats to the threat of earthquakes and tsunamis. The aim of the research is to determine the frequency distribution of the level of preparedness of Purus flat residents in facing the earthquake and tsunami disaster in Padang City. The design of this research is descriptive research, using primary data in the form of a preparedness parameter questionnaire from LIPI, namely knowledge, emergency response plans, early warning systems, and resource mobilization. The sampling technique uses a non-probability technique using accident sampling. The results of this research show that most residents' knowledge is in the sufficient category (52.5%), the emergency response plan is in the insufficient category (55.0%), the early warning system is in the insufficient category (37.5%), and resource mobilization is in the insufficient category ( 35.0%). It is hoped that these residents will be given education about the earthquake and tsunami disaster, prepare first aid kits, important telephone addresses, optimize tsunami warnings both traditional/local and national, hold regular simulations, and provide funding after a disaster occurs.Key words: emergency response, early warning system
