Sangangüey contains a prominent lava spine at its eroded summit, seen here from the west. Sangangüey was constructed on the southern flank of Las Navajas volcano. The NW and SE flanks contain 45 scoria cones that erupted during the past 300,000 years. Activity at the main edifice ceased during the Pleistocene and some cones may only be about 1,000 years old.
The steep remnant at Sangangüey volcano (center) rises 250 m above the Arroyo Caracol, an erosional valley down the SW flank. It is similar in composition to surrounding layered lava flows, but contains less glass, which suggests slower cooling. The Arroyo Caracol exposes a 700-m-thick section showing the interior stratigraphy of the cone.
Multiple scoria cones have formed across the flanks of Sangangüey. The light-colored cone below the skyline and to the right is cone C4, and the darker cone on the lower right horizon is D8. These two cones are part of the youngest group of cones and may be only 1,000 years old. A lava flow from the C4 crater traveled down the south flank of Sangangüey between the two older cones of B3 and B4, in the foreground.
Sangangüey is an eroded stratovolcano that is seen here from the SW across farmlands of the Tepic basin, with a spine visible in the summit crater. The NW and SE flanks contain 45 scoria cones that erupted during the past 300,000 years; some of these NW-flank cones are visible below the left horizon. 
The eroded Sangangüey edifice was constructed during the Pleistocene and its flanks contain 45 scoria cones, some of which have erupted during the Holocene. The cone forming the peak on the lower right horizon and the cone highlighted by the sun below and to the right of the summit in this view from the south are among the youngest.
Volcán el Molcajete (left) is the largest scoria cone on the NW flank of Sangangüey volcano (upper right). The crater opens to the NW and was the source of a lava flow that traveled across the floor of the Tepic valley.
A SE-trending chain of scoria cones extends beyond the flank of Sangangüey volcano into the Tepic basin. Cerro el Molcajete, the flat-topped cone to the right, shares the name of Volcán el Molcajete on the NW flank of Sangangüey. This NW-SE-trending alignment of Pleistocene basalt and mugearite scoria cones is seen here from the south across farmlands near the village of El Limón.
The hills in the center of the photo form part of the SE-flank cone alignment on Sangangüey volcano. This view looks to the SE from the side of cone C4. The cones extend beyond the flanks into the Tepic basin towards the Pleistocene Santa María del Oro maar that erupted through Miocene tuffs beyond the cones, which is not visible in this photo.Maps are not currently available due to technical issues.

| Copernicus Browser | The Copernicus Browser replaced the Sentinel Hub Playground browser in 2023, to provide access to Earth observation archives from the Copernicus Data Space Ecosystem, the main distribution platform for data from the EU Copernicus missions. |
| MIROVA | Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity. |
| MODVOLC Thermal Alerts | Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales. |

WOVOdat
Single Volcano View Temporal Evolution of Unrest Side by Side Volcanoes |
WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.
GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments. |
| Volcanic Hazard Maps | The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers (or other interested parties) to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences. In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. This site is for educational purposes related to volcanic hazard maps. Hazard maps found on this website should not be used for emergency purposes. For the most recent, official hazard map for a particular volcano, please seek out the proper institutional authorities on the matter. |

| DECADE Data | The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the Mapping Gas Emissions (MaGa) Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO2 to the atmosphere, but installing CO2 monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere. |
| Large Eruptions of Sangangüey | Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA). |
| EarthChem | EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS). |
