Analysis of tsunami and of macroseismic data of Lisboa 1.11.1755, M=8.4-8.9 earthquake is made. It is showed the height of 1755 tsunami in Lisboa Bay is overstated strongly. The location and the measurement of general foci are assessed. It is showed the movements in foci of Lisboa earthquake taken place along of north-eastwards system ruptures. Lisboa and its outskirts and westerly Atlantic coast of Portugal was located on periphery of 1755 earthquake’ foci. The high amplitude of the ground surface oscillations and big damage are explained of such foci location. New data on repeatability of strongest earthquakes over the range western Alpine tectonic brunch are cited. It is showed the long-lasting (five days!) Lisboa fire was related with the gas coming from the Earth by means of system ruptures.
