750:. Southwest from Pampas Onduladas lie the 181.2 kilometres (112.6 mi) long Los Carrizales lava flows, which have in part advanced to even larger distances than Pampas Onduladas but owing to a straighter course are considered to be shorter than the Pampas Onduladas lava flow, and the La Carbonilla lava flow which like Los Carrizales propagated southeastward and is located just west from the latter. Additional large lava flows are located in the western part of the field and resemble the Pampas Onduladas lava flow, such as the El Puente Formation close to the Rio Grande River of possibly recent age. Long lava flows have also been produced by volcanic centres directly south of Payún Matrú, including the 70–122 km (43–76 mi) long El Corcovo, Pampa de Luanco and Pampa de Ranquelcó flows. 609: 42: 938: 505: 445: 125: 457:(11,320 ft) Punta Sur and the approximately 3,700 m-high (12,100 ft) Cerro Matru or Payen. In the field however Cerro Matru appears smaller than Nariz. The caldera was once 8–9 km (5.0–5.6 mi) wide but erosion of its flanks and later activity have reduced its size and buried the rim below coulées, lava domes, lava flows and pumice cones that were emplaced after the caldera collapse.

Among these the Los Morados, Morado Sur and Volcán Santa María cones in the eastern and northeastern part of the field are uneroded and are probably of 723:
167–181 km (104–112 mi). The process by which such long lava flows form has been explained as "inflation" whereby lava forms a crust that protects it from heat loss; the so protected lava flow eventually inflates from the entry of new magma, forming a system of overlapping and interconnected lava flow lobes. Such lava flows are known as "sheet flows". Parts of the Pampas Onduladas lava flow have been buried by more recent lava flows.

The flow originates on the eastern side of the volcanic field in the La Carbonilla fault and eventually splits up into a shorter ("Llancanelo lava flow", 60–63 km (37–39 mi) long) northwestern and the longer southeastern branch which reaches all the way to an 517: 1328:, which collapsed, producing the ignimbrites. Different layers of magma in the magma chamber were erupted during the course of the eruption and eventually the summit of the volcano collapsed as well, forming the caldera; activity continued and emplaced lava domes and lava flows in the caldera area.
