    Chemical composition of ferromanganese nodules from a core taken in the vicinity of the Hawaiian Islands (2023)
    PANGAEA
    Details
    Publication Date: 2023-08-28
    Description: Ferromanganese nodules were retrieved at different levels inside a core taken in the vicinity of the Hawaiian Islands. Total iron contents were determined by the bichromate method with reduction by a bismuth reducing agent. Mn total content was determined by the volumetric arsenite-nitrate method, MnO2 content was determined from the active oxygen, and the MnO content was the difference between Mn total and MnO2.

    Diverse Rupture Characteristics between the 2023 Mw 7.8 and Mw 7.5 Turkey Earthquakes (2023)
    In:  XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)
    Details
    Publication Date: 2023-07-13
    Description: On 6 February 2023, an M〈sub〉W〈/sub〉 7.8 earthquake occurred on the southwestern part of the East Anatolian Fault zone (EAF), followed by an M〈sub〉W〈/sub〉 7.5 at ~100 km away on the East-West striking Sürgü fault 9 hours later. The W-Phase inversions indicate major strike-slip with dip angles of 60° for both events. A notable difference in seismic waveforms between two major earthquakes suggests different rupture characteristics. High-frequency back projection images for the M〈sub〉W〈/sub〉 7.8 event from the dense broadband ChinArray shows a NE unilateral rupture from the onset for 40 sec with the expansion to the EAF trace since ~20 s and stopping at the junction of EAF and Sürgü fault, along with some late radiation at ~40-60 s to SW at the Amanos segment of EAF. The back projection image for the M〈sub〉W〈/sub〉 7.5 event shows a main high-frequency coherent energy release for the first 10 sec over ~40 km and late weak radiations to the west near the curved Cardak fault and to the east near the Malatya fault. Preliminary slip models inverted from teleseismic data indicate a complex rupture for the M〈sub〉W〈/sub〉 7.8 event predominantly on the EAF and a localized slip for the M〈sub〉W〈/sub〉 7.5 event. The difference also exhibits in body-wave magnitude with m〈sub〉B〈/sub〉=7.5 for the M〈sub〉W〈/sub〉 7.5 and m〈sub〉B〈/sub〉=7.2 for the M〈sub〉W〈/sub〉 7.8 events. We are exploring InSAR images, hr-GNSS, and strong-motion data to constrain details in the rupture process of both events.
