2023 Kahramanmaraş earthquakes: Co-seismic deformation from Sentinel-1, LuTan-1 and ALOS-2 [ Zenodo ]

Three dimensional co-seismic surface deformation of the 6 Feburary 2023 M7.8 and M7.5 earthquake sequence across the Kahramanmaraş region near Nurdağı, Turkey. These displacement products are derived from Sentinel-1, LuTan-1 and ALOS-2 SAR images, using a combination of InSAR, multiple aperture interferometry (MAI) and speckle tracking. Check Xu et al. (2023, CEE) for more details.

2021 Maduo earthquake: Co-seismic deformation from Sentinel-1 [ Zenodo ]

Three dimensional co-seismic surface deformation of the 21 May 2021 M7.4 earthquake in Maduo, Qinghai, China. These displacement products are derived from Sentinel-1 A/B SAR images from ascending track 99 and descending track 106, both acquired on 20 and 26 May 2021, using interferometry and speckle tracking techniques. Check Xu et al. (2023, JGR) for more details.

Kirishima volcanic complex: InSAR time series from ALOS and ALOS-2 [ Zenodo ]

Surface deformation history of the Kirishima volcanic complex in Kyushu, Japan during 2006-2011 and 2014-2019 using InSAR time series analysis from ALOS and ALOS-2 satellite. The dataset covers the 2008, 2011, 2017 and 2018 eruptions at Shinmoe-dake and the 2018 eruption at Iwo-yama. Check Yunjun et al. (2021, GRL) for more details.

Galápagos volcanoes: InSAR time series from ALOS and Sentinel-1 [ Zenodo ]

Surface deformation history of the Galápagos volcanoes in Ecuador during 2007-2011 and 2014-2019 using InSAR time series analysis from ALOS and Sentinel-1 satellite. The dataset covers the 2008 eruption and 2017 dike intrusion at Cerro Azul volcano, the 2009 and 2017 eruptions at Fernandina volcano, the 2010 non-eruptive unrest at Alcedo volcano, the 2015 eruption at Wolf volcano, and the inflation prior to the 2018 eruption at Sierra Negra volcano. Check Yunjun et al. (2019) and Gregg et al. (2022) for more details.
