Volcano information in Spanish

Putana, Ollague, San Pedro, Images, and locations

Putana volcano, should say that it is a stratovolcano at the beginning. Also, it is always good to have a distance reference from any nearby town (like San Pedro, Machuca, or even El Tatio) for reference. Fumaroles, should say four "fumarolic or fumarole" fields. Check the 1952 citing of 30 fumaroles, there could just be a mention saying "Historically, there have been several reports of fumarolic activity since late XIX century, early XX century and on (Rudolph, 1952 & Casertano, 1963). The reference for the temperature of the fumarole 82-89°C were taken by Tassi et al 2011, mentioned in Henderson, so it should cite Tassi in my opinion. Some links do not work (link 13 "Putana TM Image Information". link 15 from Neimeyer Archived from the original (PDF) on 2016-03-04. Retrieved 2018-10-27.)

Lead section
A good lead section defines the topic and provides a concise overview. A reader who just wants to identify the topic can read the first sentence. A reader who wants a very brief overview of the most important things about it can read the first paragraph. A reader who wants a quick overview can read the whole lead section.

Content
A good Wikipedia article should cover all the important aspects of a topic, without putting too much weight on one part while neglecting another.

Tone and Balance
Wikipedia articles should be written from a neutral point of view; if there are substantial differences of interpretation or controversies among published, reliable sources, those views should be described as fairly as possible.

Sources and References
A Wikipedia article should be based on the best sources available for the topic at hand. When possible, this means academic and peer-reviewed publications or scholarly books.

Organization and writing quality
The writing should be clear and professional, the the content should be organized sensibly into sections.

Option 2

 * Article title
 * Olca Volcano Link to Olca-Paruma(Olca)


 * Article Evaluation
 * .The article has not much information about the volcano apart from saying it is a stratovolcano. Content wise there is no information about the seismology, volcanic gases, historic eruptions or the edifice different rocks. since there is no really much content of this volcano. However, there is another wikipedia topic about Olca-Paruma. This article is characterized as stub-class and there are wikipedia projects associated with this one. On the contrary the Olca-Paruma has a GA rating and is also part of 4 wikipedia projects. For the Olca project, there is no major organization on the structure of the page, very little media and images, therefore, is an incomplete page, but is it worth it to edit having another really similar one with more information and sources? For the Olca-Paruma project there are some broken links, some information is not cited and
 * Article Modifications Geography on the right side of the page needs a map Altitude  5705 m and 18717 ft  Olca is a Stratovolcano, located in the Central volcanic zone (CVZ) of the Andes, on the border of Chile and Bolivia
 * Geography and geological context (Regional/ Local Setting)?
 * The CVZ is suggested to be highly metamophosized rocks of at least 1Ga compose the basement of the region (pp.5), with a crust >70km thick (pp.7) with over 44 active volcanic edifices and 18 minor centers (pp.10) (Stern 2004) ... Should I mention slab and Nazca plate?
 * Geology (Basement)
 * Olca lies above Upper MiocenePliocene dacitic and andesitic volcanic products that form the Ujina ignimbrite
 * Andeciticdacitic lava flows extend up to 7 km north from the active Olca crater
 * Glaciar activity (Gardeweg 2009)
 * Rocks and lavas flows (Gardeweg 2009)
 * Navas (2019)
 * Composition
 * Gas emissions and compositionOlca.jpg gasses emission is comprised by a single warm spring at the base and a persistent fumarole field over at the crater´s dome for at least 60 years. The emissions measured in situ at the crater show a highly mixed magmatic system between high temperature temperature gasses and hydrothermal fluids (pp.132 ).
 * The gas composition indicates low concentration of H2, CO and acidic gasses, and high concentration of H2S and hydrocarbons. The stable isotopes values are low and it shows similar values of R/Ra to the ones from the CVZ (fuente). Other authors have measure the amount of SO2 using a remote sensing techniques called Differential Optical Absorption Spectrometer (DOAS) giving maximum concentration of 35 ppm.m of SO2 (this should also be changed in the Olca-paruma chain Measurements have yielded sulfur dioxide concentrations of 35 ppm over the area.[19]. ) The most recent date for SO2 were taken with a UV camera suggesting an average of 18.4 t d-1 (Conflict of interest?)
 * Satellite observation has shown temperature anomalies compared to the background of 6 K (11 °F), potentially caused by the fumarolic activity, Though through ground temperatures in the fumarole fields it reaches about 357–364 K (84–91 °C; 183–196 °F).
 * Eruptive history?
 * Other research has claimed that lava flows on the western side of Olca were erupted during the Pleistocene and that others seem to be much older. The appearance of the edifices suggest that volcanic activity migrated east over time, although validation of the proposed older dates would contradict this.
 * Unconfirmed historical eruptions are suspected to have occurred in 1865-1867 (Pritchard 2014) Gonzalez-Ferrán
 * November 1989 and March 1990 intense degassing
 * Been actively degassing for ~60 years from the dome at the summit (foto)
 * Seismic activity
 * There are report of low-intensity seismic accompanied with fumarolic activity during 1989 and 1990. Conducted seismic activity show 3 potencial swarms in 2010 without a clear interpretation
 * Geothermal system
 * Studies show a hydrothermal activity, with low resistivity layers over a hotter interlayer which could produce between 75 and 450 MWe in the vecinicty of the volcano(reyes 2011) Hazard map is available (orozco bertin 2013) bajo peligro afecta a 10 personas, productos volcanicos podrian llegar a lagunas.

 * The regional characteristics have been documented by worner (1992 and 2000), there is also a new detailed work by Sofia Navas (UCN).
 * Sernageomin considers this volcano active and is permanently monitored.
 * Geothermal works by Reyes (2011)
 * Pritchard (2014) has compiled evidence of seismology

 * Article Evaluation

Overview

 * Olca es un estratovolcan compuesto ubicado en la Zona Volcanica Central de los Andes (ZVCA), en la frontera de entre Chile y Bolivia. Se emplaza en el medio de un cordón montañoso de 15 km de largo compuesto de varios estratovolcanes. El cerro Minchincha se emplaza al oeste, y el Paruma al este. Su composición es principalmente andecítica-dacítica, con flujos de lavas que se deslizan por las laderas del volcán por varios kilometros. La actividad del volcán comenzó durante el Pleistoceno y se ha mantenido durante el holoceno, donde la última actividad conocida del cordón fue una erupción de uno de sus flancos entre 1865 y 1867. Este complejo presenta morrenas, las cuales son evidencia de glaciares. Hoy en día presenta una actividad fumarolica persistente

Historia Geológica

 * Se emplaza sobre unidades volcánicas correspondientes a la Ignimbrita Ujina y otras y unidades de edad Miocena Superior-Plioceno Inferior
 * presenta flujos de 8 km de longitud en el flanco SE con características de levees y ojivas muy bien preservadas
 * Morrenas en flaco sur

Emisiones de gases y composición quimica

 * La emision de gases volcanicos se encuentra rpincipalmente asociada a una pluma persistente en la cima del volcán Olca y una fuente termal en la base. La actividad fumarólica de la cima se encuentra en el flanco norte del crater del como y se ha mantenido constante por los ultimos 60 años. La emisión medida con instrumentos in situ, ha permitido deteminar que es un sistema magmático mixto con gases magmáticos e hidrotermales. (pp.132 ). Además, la composición de los gases indica una concentración baja de H2, CO, y otros gases ácidos, mientras que los gases H2S e hidrocarburos se encuentran en altas concentraciones. Los isotopos estables no presentan grandes variaciones respecto de aqueellos de la ZVCA, especialemte con valores de R/Ra.
 * Other authors have measure the amount of SO2 using a remote sensing techniques called Differential Optical Absorption Spectrometer (DOAS) giving maximum concentration of 35 ppm.m. of SO2

Option 4

 * Article title
 * Spanish version of Putana volcano


 * Article Evaluation
 * Start from scratch, I could actully used some of the translations from the Putana volcano edits I do, and start adding more information to make it look better and similar to the English version. I will have more freedom to do edits but I will use the same sources as the english version


 * Sources
 * apart from the ones decribed in the putana volcano I will also add some information from sources like the smithsonian global volcanism program.
