“…The above volume estimates do no take into account ash fallout, which can amount to as much as three to eight times the cone volume in extreme cases where activity was strongly explosive (e.g., Lathrop Wells, Paricutin, Fries 1953). This case might apply to C. La Tinaja and C. El Zoyate volcanoes (both have large cone volumes and are surrounded by thick fallout deposits), but the volume of ash produced by most other cones is likely to be smaller (<twice the cone volume), similar to recent cones at Etna volcano (Fornaciai et al 2010;Behncke et al 2006). Considering that ash products generally amount in average to twice the cone volume, the total erupted volume increases to between 3.8 and 4.3 km 3 for the Holocene.…”

The 690 km 2 Tacámbaro-Puruarán area located at the arc-front part of the Michoácan-Guanajuato volcanic field in the Trans-Mexican Volcanic Belt (TMVB) records a protracted history of volcanism that culminated with intense monogenetic activity in the Holocene. Geologic mapping, 40 Ar/ 39 Ar and 14 C radiometric dating, and whole-rock chemical analyses of volcanic products provide insights to that history. Eocene volcanics (55-40 Ma) exposed at uplifted blocks are related to a magmatic arc that preceded the TMVB. Early TMVB products are represented by poorly exposed Pliocene silicic domes (5-2 Ma). Quaternary (<2 Ma) volcanoes (114 mapped) are mainly scoria cones with lavas (49 vol.%), viscous lava flows (22 vol.%), and lava shields (22 vol.%). Erupted products are dominantly either basaltic andesites (37 vol. %), or andesites (17 vol.%), or span across both compositions (28 vol.%). Basalts (9 vol.%), dacites (4 vol.%), shoshonites (2 vol.%), and other alkali-rich rocks (<3 vol.%) occur subordinately. Early-Pleistocene volcanism was bimodal (dacites and basalts) and voluminous while since 1 Ma smallvolume eruptions of intermediate magmas have dominated.Higher rates of lithospheric extension in the Quaternary may have allowed a larger number of small, poorly evolved dikes to reach the surface during this period. Eruptive centers as old as 1.7 Ma are aligned in a NE direction parallel to both, basement faults and the direction of regional compressive stress, implying structural control on volcanic activity. Data suggest that volcanism was strongly pulsatory and fed by localized lowdegree partial melting of mantle sources. In the Holocene, at least 13 eruptions occurred (average recurrence interval of 800 years). These produced~3.8 km 3 of basaltic andesitic to andesitic magma and included four eruptions dated at~1,000; 4,000; 8,000; and 11,000 years BC (calibrated 14 C ages). To date, this is one of the highest monogenetic eruption frequencies detected within such a small area in a subduction-related arc-setting. These anomalous rates of monogenetic activity in an area with thick crust (>30 km) may be related to high rates of magma production at depth and a favorable tectonic setting.

“…Therefore, the measured volumes (Table and Figure c) may underestimate the total volume of erupted material as they represent only the material contained in the cone itself. Such an underestimate is also common for terrestrial scoria cones if their volume is calculated in a similar way used in this study [e.g., Favalli et al ., ; Bemis et al ., ; Kereszturi et al ., ]; however, this underestimate may be avoided by using isopachs or several continuous light detection and ranging measurements [ Fornaciai et al ., ], which are, however, not available on Mars.…”

Scoria cones on Mars: Detailed investigation of morphometry based on high‐resolution digital elevation models

We analyze the shapes of 28 hypothesized scoria cones in three regions on Mars, i.e., Ulysses and Hydraotes Colles and Coprates Chasma. Using available High-Resolution Imaging Science Experiment and Context Camera (CTX) digital elevation models, we determine the basic morphometric characteristics of the cones and estimate from ballistic modeling the physical parameters of volcanic eruptions that could have formed them. When compared to terrestrial scoria cones, most of the studied cones show larger volumes (up to 4.2 × 10 9 m 3 ), larger heights (up to 573 m), and smaller average slopes. The average slopes of the Ulysses, Hydraotes, and Coprates cones range between 7°and 25°, and the maximum slopes only rarely exceed 30°, which suggests only a minor role of scoria redistribution by avalanching. Ballistic analysis indicates that all cones were formed in a similar way, and their shapes are consistent with an ejection velocity about 2 times larger and a particle size about 20 times smaller than on Earth. Our results support the hypothesis that the investigated edifices were formed by low-energy Strombolian volcanic eruptions and hence are equivalent to terrestrial scoria cones. The cones in Hydraotes Colles and Coprates Chasma are on average smaller and steeper than the cones in Ulysses Colles, which is likely due to the difference in topographic elevation and the associated difference in atmospheric pressure. This study provides the expected morphometric characteristics of Martian scoria cones, which can be used to identify landforms consistent with this type of activity elsewhere on Mars and distinguish them from other conical edifices.

“…This approach has already been applied extensively in volcanology, where high-precision morphometric and volumetric measurements of surface features are crucial for understanding highly dynamic processes. Some classic examples are lava-flow and dome emissions [23]- [25], [31], [32] and cinder cone geometries [33].…”

Abstract-We present a workflow to create, scale, georeference, and integrate digital elevation models (DEMs) created using open-source structure-from-motion (SfM) multiview stereo (MVS) software into existing DEMs (as derived from the light detection and ranging data in the presented cases). The workflow also maps the root-mean-square error between the base DEM and the SfM surface model. This allows DEM creation from field-based surveys using consumer-grade digital cameras with open-source and custom-built software. We employ this workflow on three examples of different scales and morphology: 1) a scoria cone on Mt. Etna; 2) a lava channel on Mauna Ulu (Kīlauea); and 3) a flank collapse scar on Mt. Etna. This represents a new approach for rapid low-cost construction and updating of existing DEMs at high temporal and spatial resolutions and for areas of up to several thousand square meters. We assess the self-consistency of the method by comparison of DEMs of the same features, created from independent data sets acquired on the same day and from the same vantage points. We further evaluate the effect of grid cell size on the reconstruction error. This method uses existing DEMs as a georeferencing tool and can therefore be used in limited access and potentially hazardous areas as it no longer relies exclusively on control targets on the ground.
