The second phase went from October 18, 1943 to January 8, 1944 and is called Sapichi, meaning child, referring to the formation of a lateral vent and other openings on the north side of the cone. Ash and bombs continued to be ejected but the new vent sent lava towards the town of San Juan Parangaricutiro, forcing its permanent evacuation. By August, the town was completely covered in lava and ash, with only the upper portions of the main church still visible. The evacuations of Parícutin and San Juan were able to be accomplished without loss of life due to the slow movement of the lava. These two phases lasted just over a year and account for more than 90% of the total material ejected from the cone, as well as almost four-fifths (330 meters) of the final height of 424 meters from the valley floor. It also sent ash as far as Mexico City.
