Detecting groundwater level changes related to the 2016 Kumamoto Earthquake
This study presented the first attempt to detect precursory changes in groundwater level before the 2016 Kumamoto Earthquake. This detection was...

Placing engineering in the earthquake response and the survival chain
Earthquakes injure millions and simultaneously disrupt the infrastructure to protect them. This perspective argues that the current post-disaster...

The preparatory process of the 2023 Mw 7.8 Türkiye earthquake
To verify the existence of a preparatory process for the 6 February 2023, Mw 7.8 Kahramanmaraş earthquake, southern Türkiye, we analyze the temporal...

Adaptive estimation of the Gutenberg–Richter b value using a state space model and particle filtering
Earthquakes follow an exponential distribution referred to as the Gutenberg–Richter law, which is characterized by the b value that represents a...

Radon concentration in seawater as a geochemical indicator of submarine fault activity in the Yatsushiro Sea, Japan
This study examined the relationship between radon ( 222 Rn) concentrations in seawater and crustal activity in the Yatsushiro Sea by investigating the...

Urban water supply systems’ resilience under earthquake scenario
Threats to water supply systems have increased in number and intensity. Natural disasters such as earthquakes have caused different types of damage...
-
Dynamics between earthquakes, volcanic eruptions, and geothermal energy exploitation in Japan
Intruding magma brings high temperatures close to the surface, thus offering possibilities for harnessing large amounts of heat for geothermal...

Temporal variation in scattering and intrinsic attenuation due to earthquakes in East Asia
Separated attenuation values have not been used in post-seismic variation research, although the scattering attenuation ( Q s −1 ) parameter that can be...

Preseismic atmospheric radon anomaly associated with 2018 Northern Osaka earthquake
Despite the challenges in identifying earthquake precursors in intraplate (inland) earthquakes, various hydrological and geochemical measurements...

Tomography of the 2016 Kumamoto earthquake area and the Beppu-Shimabara graben
Detailed three-dimensional images of P and S wave velocity and Poisson’s ratio (σ) of the crust and upper mantle beneath Kyushu in SW Japan are...

Real-time discrimination of earthquake foreshocks and aftershocks
Immediately after a large earthquake, the main question asked by the public and decision-makers is whether it was the mainshock or a foreshock to an...
-
Forecasting the magnitude of the largest expected earthquake
The majority of earthquakes occur unexpectedly and can trigger subsequent sequences of events that can culminate in more powerful earthquakes. This...

On catching the preparatory phase of damaging earthquakes: an example from central Italy
How, when and where large earthquakes are generated remain fundamental unsolved scientific questions. Intercepting when a fault system starts...

Study on thermal insulation and seismic effect for fault-crossing tunnel in high geothermal area
The fault-crossing tunnel in high geothermal areas can be severely damaged under strong earthquake. In this paper, numerical models were established...
-
Stable isotopes show that earthquakes enhance permeability and release water from mountains
Hydrogeological properties can change in response to large crustal earthquakes. In particular, permeability can increase leading to coseismic changes...
-
SURE 2.0 – New release of the worldwide database of surface ruptures for fault displacement hazard analyses
Surface rupturing data from the historical earthquakes is used for obtaining empirical regression parameters for fault displacement hazard...

Strain accumulation and release associated with the occurrence of SSEs in the subduction zones of the Japanese Islands
We investigated the spatiotemporal changes in strain associated with the occurrence of slow slip events (SSEs) in the subduction zones of the...

A two-phase model of collective memory decay with a dynamical switching point
Public memories of significant events shared within societies and groups have been conceptualized and studied as collective memory since the 1920s....

Earthquake-induced structural deformations enhance long-term solute fluxes from active volcanic systems
Evidence for relationships between seismotectonic activity and dissolved weathering fluxes remains limited. Motivated by the occurrence of new...

Hybrid predictor for ground-motion intensity with machine learning and conventional ground motion prediction equation
The use of strongly biased data generally leads to large distortions in a trained machine learning model. We face this problem when constructing a...
