Tectonic map of the SE Zagros Mountains. The major faults shown are Main Zagros Reverse Fault (MZRF), Zendan-Minab-Palami Fault (ZMPF), Mountain Frontal Fault (MFF) and High Zagros Fault (HZF). The regional SHmax direction (arrow in the upper left corner) has been calculated from the major earthquake focal mechanisms in the SE Zagros from the CMT and ISC catalogues. GPS vectors are from F. Khorrami et al. (2019). Triangles denote seismic stations that returned a splitting measurement result. Circles are aftershocks used in the shear-wave splitting analysis. Stars denote the Tiab, Fin and Qeshm events. The inlet in the upper right corner shows a blown-up map of the faults in the Faryab region. The black petals in the rose diagram are the nodal planes of the aftershocks of the Tiab earthquake, and the green petals denote the P-axes derived from those aftershocks (A. Gholamzadeh et al. 2009). The local SHmax direction in Qeshm island (represented by arrow) was derived from the large earthquake focal mechanisms, classified as grade A (shown in black) and grade B (shown in grey) solved by E. Nissen et al. (2010).

Top-level architecture of the WEAVE observatory control system (OCS) software and its interfaces to the wider WEAVE software environment. The AG subsystem, which is the focus of this paper, is highlighted in red. The diagram illustrates the principal communication pathways linking the AG system to other components, including the WEAVE sequencer, telescope control system (TCS), acquisition cameras, image archive, and Redis-based messaging infrastructure. These interfaces define the flow of commands, telemetry, and image data required to perform automated acquisition and closed-loop guiding during WEAVE observations. The diagram updates the architecture originally presented in fig. 1 of S. Picó et al. (2018) to reflect the current system following integration and commissioning, and to emphasize the AG subsystem described in this work.

Seismotectonic context and stations used to build the catalogue. (A) Map of the study area. Stations are shown as squares (PE network, permanent), upright triangles (C, C1, CX and GT networks, permanent) and inverted triangles (6B network, temporary), with the colour indicating the number of days that the station was active during the study period. The −4200 m contour of the Nazca Ridge is shown as a full white line, and the approximate edge of the Iquique Ridge is shown as a dashed white line. Slab2 (G.P. Hayes et al. 2018) contours are shown in dark red. Blue dashed ellipses correspond to the approximate rupture areas of historical earthquakes (D. Comte & M. Pardo 1991; J.L. Sennson & S.L. Beck 1996), while smooth pink lines show the 1 m contours of the Pisco 2007 (North), Arequipa 2001 (centre) and Iquique 2014 (South) earthquakes (B. Lovery et al. 2024; M. Chlieh et al. 2011). The plate motion is taken from E. Kendrick et al. (2003). NFZ: Nazca Fracture Zone; IR: Iquique Ridge. (B) Number of stations active for each day of the study period.

Morphological and tectonic framework of the ECS basin and adjacent regions. The grey shaded area represents the main extent of the ECS shelf basin, with the Xihu Sag outlined by red dashed lines. Orange polygons mark the main uplift zones, while light grey polygons denote depressions. The red solid line indicates the location of the profile shown in Fig. 3. The solid black line represents the wide-angle seismic profile in the ECS margin (J. Qi et al. 2020; Z. Wu et al. 2021). The inset map shows the location of the study area (red box) within the west Pacific tectonic framework.

A map of the northern Main Ethiopian Rift (NMER) overlain with earthquakes (circles) published by the USGS National Earthquake Information Center (NEIC) from 2024 December 21 through 2025 March 17 (USGS 2017a, b). White triangles mark the locations of Holocene volcanoes (GVP 2025a), thin black lines trace the local fault system (A. Agostini et al. 2011) and the shaded pink areas show Quaternary magmatic segments as mapped in D. Keir et al. (2006) (after N.J. Hayward & C.J. Ebinger 1996). The Fentale–Dofen magmatic segment (FDMS ) is labelled and marked with a white arrow. Earthquakes are scaled by magnitude and coloured by origin time. We overlay select features mapped in E. Lewi et al. (2025), which include the thick red line that traces the 50-km-long dyke region, the thick dashed black lines that trace inferred faults with slip and several stars that mark the locations of various surface manifestations. From the southern end to the northern end of the dyke, the brown star marks the location of a landslide, the green stars mark the locations of surface ruptures, the purple star marks a location of building damage and the orange stars mark the locations of two phreatic eruptions. The inset map shows the location of the NMER relative to the Ethiopian Western Plateau (WP), Ethiopian Southeastern Plateau (SEP), Afar Depression (Afar Dep.) and the central and southern Main Ethiopian Rift (CMER and SMER, respectively). Within the inset map, the northeast–southwest trending red line traces the rift boundary (D. Hasterok et al. 2022), thick black lines trace the large border faults (as mapped in D. Keir et al. 2006), blue shaded areas are local bodies of water and the white dashed box outlines the region of the larger map. Common symbols between the large and inset maps represent the same features and the globe in the legend marks the location of the NMER with a black rectangle.
