New Landslide Reporting Tool Uses Social Media and AI

by Deepa Padmanaban 1 September 20221 September 2022

The tool extracts landslide information in real time, which could advance landslide research as well as disaster response.

A small coastal shipping town in Japan is devastated by an earthquake. In this photo taken from a plane, the wreckage of hundreds of buildings can be seen, and only a handful remain standing. In the center of the image, a small yacht is perched on top of one of the only remaining buildings. The town is surrounded by mountains and forests. One of the plane’s wheels is visible in the lower left corner of the image.

Estimating Land Loss in River Deltas

by Mohammed El-Said 31 August 202219 September 2023

Some deltas are susceptible to land loss during sea level rise, whereas others gain land because of changes in the courses of rivers.

The inside of the KamLAND antineutrino detector comprises a grid of tessellated segments, parallelograms and trapezoids, that fit together to form a sphere. Each segment of the detector, which is black, has 16 sensors, which are gold, arranged in a 4 by 4 pattern. Each segment is connected by a white border. At the center of the detector, and image, is a green circle.

Irrigation in Indo-Gangetic Plain Has Little Impact on Heat Stress

Rishika Pardikar, Science Writer by Rishika Pardikar 30 August 202215 April 2024

Irrigation-related cooling during summer months is overestimated by roughly 5 times, highlighting the need for climate models to accurately reflect local agricultural practices.

A boy in a striped t-shirt and shorts steers a long, narrow, and shallow boat with a long pole across a shallow body of water. The boat is laden with rocks. In the background is a marshland with a small group of people and a few tents, and beyond that are forests and mountains. One patch of forest on the right side of the mountains has been stripped bare by a past landslide.

光纤技术为滑坡监测开辟新领域

Aaron Sidder, freelance science writer by Aaron Sidder 30 August 202230 August 2022

为了研究中国三峡水库沿线的一处滑坡,研究人员在现场布设了光纤传感器,来监测地下温度、湿度和应变。

A thermal image of coastline shows plant evaporative stress in varying shades of red and green. Waterways in black snake through the mangrove forest, becoming narrower toward the top of the image. Land that touches or is near a waterway tends to have low evaporative stress and shows up as bright green, whereas areas farther inland indicate high evaporative stress and appear red.
