Volcanes y Ciencia Hoy does not state the data they used for this map.  The last maps/data by Open Data La Palma, Copernicus, or IGME are all earlier than this.  Idafe Blog ( https://www.idafe.com/German/51blog_de.html ) of 17 Oct, 9:30h, states that the "Fussballfeld in La Laguna, welches lange nur zur Hälfte mit Lava bedeckt war, ist nicht mehr auffindbar" ("The football field, only half of which used to be covered by lava, is no longer there.")
