Before the inhabitants of Los Angeles had time to move away from catastrophic forest fires, as NASA experts warn of a new threat to the register: slow landslides are accelerating, as a result of which hundreds of buildings on the Palos Vertes peninsula can go under the water column, writes Science Alert.
Researchers hope that the threat will not be immediate, but such unstable lands can suddenly collapse, as it was already with the landslide in MAD CRIC in 2017, so researchers are trying to better understand the warning signs.

It's no secret that this region on the Palos Vertes Peninsula is slowly sliding towards the ocean for decades. However, the new radar data from the NASA reactive laboratory showed that the speed of this landslide directed to the ocean seems to have increased. Moreover, scientists have found that the area of \u200b\u200bland that is on the movement today has also increased significantly since 2007, when the experts of the Geological Service of California have applied risk to the map.
According to geophysicist Alexander Handverger, the results indicate that today the risk zone has expanded significantly. Scientists have found that the area of \u200b\u200bthe land that has expanded has expanded, and the rate of landslide is more than sufficient to be at risk of human life and infrastructure.
During the study, scientists have combined radar measurements and data obtained from the Copernicus satellite of the European Space Agency. The results indicate that in the fall of 2024, residential lands shifted at a speed of up to 10 centimeters per week towards the Pacific Ocean. This increase in traffic followed record precipitation in 2023, as well as for further strong rains in early 2024.
According to NASA physicist, Dalia Kirshbaum, the vast majority of landslides around the world are caused by intense and continuing precipitation. Alas, the global warming of the earth only worsened the conditions of fires, and also increased over -powerful storm streams, making landslides an incredible thunderstorm.
As the earthly atmosphere heats up, its ability to retain water increases - this leads to extreme rainfalls, as well as a stronger and more large -scale drought.
This sharp acceleration of the water cycle creates a phenomenon called a hydroclimatic whip, when the conditions quickly change from extremely wet to extremely dry and back.
Back in 2022, the Handverger and his colleagues found that the landslides were moving faster in the rainy seasons than in dry. Moreover, soil moisture no longer plays much significance. In further work, scientists plan to continue the study of these risks in order to shed light on how hydroclimatic whip will affect the movement of our planet.
