Indonesia - Earthquake on Nov 23 2025

This data contain of shake information caused by Earthquake M 6.2 - 32 km S of Mamuju, Indonesia (2.976°S 118.901°E) at 2021-01-14 18:28:18 (UTC)

An Interferogram of the devastating earthquake in Indonesia last July 29, 2018 with a magnitude of 6.4. Data were processed using 2 Sentinel 1 data using repeat pass interferometry. One cycle (cold to hot color) means half of the radar wavelength which is approximately 3.5 - 7.5 cm wavelength. The data shows vertical ground displacement with respect to the satellites line of sight (LOS).

Imagery captured by Digital Globe on 2 October 2018 of Palu, Indonesia. The data is available as a service https://www.arcgis.com/home/item.html?id=d0ff196041e04e0d8d3a09e1e435625d where the tiffs can also be downloaded.

**UNOSAT code EQ20221121IDN, GDACS Id: 1347183** Live web map providing geospatial information about damaged caused by the earthquake that stroke Indonesia on 21 November 2022. This web map gives an updated overview over potentially damaged and damaged buildings based on very high-resolution satellite images.

**UNOSAT code VO20221206IDN, GDACS Id: 1000057** This map illustrates the potentially affected areas by pyroclastic flow/deposits of the December 2022 Semeru mount eruption in East Java (Indonesia) as inferred from post eruption satellite images VRRS, Worldview-3, Spot 6, and Sentinel-2, images acquired on 8, 9, 11 & 12 Dec. 2022 respectively. Within this area, UNOSAT has identified 208 affected structures and 221 structures are potentially affected. Based on Worldpop population data, WSF urban areas data, about 7ha of urban areas are affected by the pyroclastic flow/deposit and about 8,000 people are potentially directly exposed to pyroclastic flow in this zone. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT).

**UNOSAT code VO20221206IDN, GDACS Id: 1000057** This map illustrates the potentially affected areas by pyroclastic flow/deposits of the December 2022 Semeru mount eruption in East Java (Indonesia) as detected by satellite images acquired on 4 Dec 2022 10km SE Mount Semeru. Based on analysis of Worldview-3, Spot 6 and Sentinel-2 images acquired on 9, 11 & 12 Dec. 2022 respectively, about 460ha of land appear to be severely affected by the volcanic eruption induced effects in the analyzed area of about 2,000ha. Within this area, UNOSAT has identified 206 affected structures and 10 potentially affected structures. Based on Worldpop population data and affected area by the pyroclastic flow/deposit, about 1,500 people are potentially exposed in this zone. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT).
