<![CDATA[Indonesia is located at the junction of three tectonic plates and has many active faults. The consequence of this tectonic arrangement makes Indonesia prone to earthquakes. Therefore, earthquake mitigation efforts based on an early warning system need to be done. The design of an earthquake strength estimation system, based on python, for this early warning, analyzes the initial phase of the first three seconds since the arrival of the P wave, using parameters in the form of Pd (the maximum amplitude of the first three seconds of the arrival of the P wave). The resulting tools and systems consist of hardware in the form of Raspberry Pi3B + and ADXL345. The system will detect in real time and automatically trigger an earthquake using the STA / LTA method. When the Pd and Td parameters have been obtained, the system will calculate and issue earthquake strength information, in the form of magnitude and intensity scale of earthquake damage MMI (Modified Mercally Intensity), which will then be sent automatically via the telegram application. Testing of tools and systems was carried out in an earthquake simulator, using the Padang earthquake parameters on 30 September 2009, 17:16:09 WIB. The results of the test produce an intensity scale of VIII MMI, these results are close to the results of the BMKG for the earthquake, with an intensity scale of VIII MMI. From these results the designed tools and systems can be used to provide early warning in the event of an earthquake.]]>
