On 29 February 1960, an earthquake struck the city of Agadir, Morocco, killing between ten and fifteen thousand Moroccans and Europeans and damaging the majority of the city's structures. Drawing on data from seismographs, witness accounts, and direct observations of destruction, international teams of experts working in the aftermath of the disaster rewrote Agadir as a seismically vulnerable space. In the process, they depoliticized destruction and assigned responsibility for the devastation of the city's poorest neighborhoods to "natural" forces and ineffective "traditional" building practices. Once established in the work of geologists, seismologists, and engineers, the notion of seismic risk shaped the material and moral trajectories of reconstruction during the first decade of Morocco's independence from France. As it cut across scientific, engineering, and bureaucratic domains, seismic risk gave rise to projects aimed less at controlling nature than at redistributing vulnerability and authority among experts, administrators, and inhabitants in Agadir.

The Bohai Sea is facing multidirectional pressure from economic development and pollutant emissions. Magnetic minerals and heavy metal concentrations in the sediments of core M5 from the Bohai Sea were performed. The results of concentration-related magnetic parameters, heavy metal contents, and PLI (Tomlinson pollution load index) illustrate there are essential linkages of the sources, migration, and deposition.

The tsunami caused by the Tonga submarine volcanic eruption that occurred at 13:15 Japan Time (JST) on January 15, 2022, exposed a blind spot in Japan's tsunami monitoring and warning system, which was established in 1952 for local tsunamis and expanded to distant tsunamis after the 1960 Chile tsunami. This paper summarizes how the warning system responded to the unprecedented tsunami, the actual evacuation process, and the damage it caused in Japan. Initially, the tsunami from the volcanic eruption was expected to arrive at approximately midnight with amplitudes of less than 20 cm.

Fatal geohazards result in severe losses of life and property worldwide, thus urging many large-scale studies of such geohazards. Further research on hotspots prone to fatal geohazard identified in national-scale studies is critical for government geohazard prevention. It has been pointed out that more detailed small-scale (sub-national) studies are essential for the hotspots (e.

Chilean geography exposes the country to high-level risks such as earthquakes and tsunamis. The disasters of 1930, 1960, 2010, and 2014 testify to the continuous link between human survival and disasters. However, new hazards have appeared ever since -i.

Trees growing in the tectonically active and climatically sensitive regions, such as the Tibetan Plateau, frequently suffer damage from strong earthquakes and extreme hydro-climatic events. Spruce trees in the Jiuzhaigou National Park exhibited abrupt periods of growth suppression with durations of 3-9 years, which was demonstrated to have recorded five seismic events during the last 350 years after excluding the climatic impacts. The ring-width reductions occurred immediately after earthquakes in the growing seasons of 1748, 1879 and 2017, and one year later in 1961 when the earthquake occurred after the growing season in 1960.
