Landslides triggered during the 2018 Lombok, Indonesia earthquake sequence timed with Sentinel-1

This is a dataset of landslides triggered during a sequence of earthquakes in Lombok, Indonesia, 2018, intended as a supplement to a paper currently in review for the journal Earth Surface Dynamics (discussion preprint at Burrows et al. 2024). Two files are included (i) a dataset of landslides with area > 2000 m2 with timing information derived from SAR amplitude time series and (ii) a dataset of landslides of landslides with area > 3960 m2 with timing information derived from SAR amplitude and InSAR coherence. (ii) also includes information on landslide reactivations inferred using InSAR coherence. In both files, the dataset includes only landslides for which a strong enough timing signal could be obtained using SAR i.e. a subset of the complete inventory. A full polygon inventory of landslides triggered during the earthquake sequence has previously been published as a supplement to Ferrario (2019). Landslides are assigned to one of four events using SAR: EQ1: Mw 6.4 on 28/07/2018 EQ2: Mw 6.9 on 05/08/2018 EQ3: Mw 5.9 on 09/08/2018 EQ4: Mw 5.8, 6.3 and 6.9 on 19/08/2018.
