DescriptionTwo domes form the Firura volcano, which has a low relief of {{convert|500|m}}.[1] Lava flows and stratovolcanoes form a {{convert|10|-|12|km}} long field. Aside from the main summit Firura, there also are Soncco Orcco ({{convert|5191|m}}), Jahsaya ({{convert|5144|m}}) and separating Firura from Solimana Antapuna ({{convert|4852|m}}). The complex has generated basaltic or basaltic andesite lava flows that reach down into inhabited areas, as well as an ignimbrite resulting from the collapse of the ancient crater. Date of last volcanic activity is Pleistocene to Holocene but it doesn't appear to be a major hazard.[6][7] Much of the southern side of the volcano above {{convert|5300|m}} altitude is covered with perennial snow. A small glacier (>{{convert|0.5|km2}}) is found on the southern summit of Firura and reaches down to {{convert|5255|m}}. This glacier appears to be located above the local equilibrium line altitude.[1] Firura has well preserved moraine systems. A major moraine system with a relief of {{convert|80|-|100|m}} was left by the Last Glacial Maximum, although expansion of glaciers on the northern flank was constrained on a high plateau. The prevalent aridity of the climate impedes the degradation of these moraines.[1] References1. ^1 {{cite web|last1=Gómez|first1=Juan Carlos|last2=Siebe|first2=Claus|last3=Sánchez-Nuñez|first3=Juan Manuel|last4=Arce|first4=José Luis|last5=Macías|first5=José Luis|title=Caracterizacion geologica de los depositos de avala ncha de escombros en Chuquibamba y Cotahuasi, region Arequipa|url=http://biblioteca.sernageomin.cl/opac/DataFiles/14127_pp_1024_1026.pdf|website=biblioserver.sernageomin|publisher=SERNAGEOMIN|accessdate=29 February 2016|archiveurl=https://web.archive.org/web/20160229081941/http://biblioteca.sernageomin.cl/opac/DataFiles/14127_pp_1024_1026.pdf|archivedate=29 February 2016|language=es}} [1][2][3][4]2. ^1 {{cite journal|last1=de Silva|first1=SL|last2=Francis|first2=PW|title=Potentially active volcanoes of Peru-Observations using Landsat Thematic Mapper and Space Shuttle imagery|journal=Bulletin of Volcanology|date=March 1990|volume=52|issue=4|pages=286–301|doi=10.1007/BF00304100}} 3. ^1 {{cite journal|last1=Thouret|first1=J.-C.|last2=Wörner|first2=G.|last3=Gunnell|first3=Y.|last4=Singer|first4=B.|last5=Zhang|first5=X.|last6=Souriot|first6=T.|title=Geochronologic and stratigraphic constraints on canyon incision and Miocene uplift of the Central Andes in Peru|journal=Earth and Planetary Science Letters|date=November 2007|volume=263|issue=3-4|pages=151–166|doi=10.1016/j.epsl.2007.07.023}} 4. ^1 2 3 4 5 6 {{cite journal|last1=Bromley|first1=Gordon R.M.|last2=Hall|first2=Brenda L.|last3=Rademaker|first3=Kurt M.|last4=Todd|first4=Claire E.|last5=Racovteanu|first5=Adina E.|title=Late Pleistocene snowline fluctuations at Nevado Coropuna (15°S), southern Peruvian Andes|journal=Journal of Quaternary Science|date=March 2011|volume=26|issue=3|pages=305–317|doi=10.1002/jqs.1455}} }}{{Andean volcanoes}} 6 : Volcanoes of Peru|Mountains of Arequipa Region|Andean Volcanic Belt|Mountains of Peru|Pleistocene volcanoes|Pleistocene Peru |
