📍New paper out!
We explore how to detect floods in arid regions better using #Sentinel -1 SAR data. These areas are often ignored in global flood mapping, but our work highlights a new approach that improves detection by up to 50%!

On 22 July 2024 a pair of landslides in the same location at Kencho Shacha Gozdi in Gofa Zone, Ethiopia is believed to have killed at least 55 people. The trigger is thought to have been heavy rainfall.

Overexploitation of #groundwater may cause #landsubsidence due to compaction of aquitards and aquifer materials.
This can result in serious settlement of building foundations, infrastructure damage and increased flood risk in coastal cities.

~ a daily #groundwater #reservoir depletion of 5 Million Cubic Meter (MCM) across Iran. This prompted @IranNewspaper, the official daily newspaper of the government, to quickly report about this crisis.

چه کسی فکر می‌کرد نرخ تاراج آب از آبخوان در استان گلستان بیشتر از استان‌هایی چون فارس، اصفهان و تهران است؟
در استان گلستان دقیقا چه خبر است که با چنین شتابی آینده را به حراج نهاده‌اند؟

A @Planet satellite image shows that the 29 April 2024 Mai Mahiu disaster in Kenya was caused by a channelised debris flow, which was formed from an extraordinary concentration of shallow landslides in the Kijabe Hills. About 130 people were killed:- eos.org/thelandslideblog/mai…

A detailed satellite survey of land subsidence in Iran from 2014 to 2020 shows that 3.5% of the country’s land area is subsiding due to groundwater pumping for irrigation. scim.ag/6W6

Groundwater loss in Iran is taking on dramatic proportions. In some regions, the ground is sinking almost 40 centimeters per year & huge fissures are opening up. Click here for the news about the latest study of GFZ researcher @MahdiMotagh & his colleague gfz-potsdam.de/en/press/news…

A great presentation by professor @MahdiMotagh on mining induced subsidence.

A recent paper in the journal Engineering Geology (Vassileva et al. 2023) describes how heavy rainfall triggered >40 m of movement in a landslide that had been reactivated by a dam:

Excited to share our work on InSAR phase-based tropospheric correction using texture info. We found texture is relatively insensitive to topo-correlated deformation, thus, providing superior performance w/o compromising defo signals! @QingyueYan31126
