Climatic drivers prevail in montane and lowland Odonata latitudinal diversity gradients, but human modification erodes lowland patterns

Ecography, EarlyView.
Latitudinal diversity gradients (LDGs) arise from the interplay of historical, ecological, and evolutionary processes, yet these drivers may differ across landforms. Mountains, with steep elevational and climatic gradients, often sustain distinct diversity dynamics compared with adjacent lowlands, where vertical climatic gradients are weak and human ...

Evaluating Seismic Resistance and Energy Dissipation of CFRP‐Reinforced Concrete Frames Under Monotonic Loading

Earthquake Engineering and Resilience, EarlyView.
“It was found that good ductility can be achieved in CFRP‐strengthened frames, and this result was validated through experimental testing.” ABSTRACT Reinforced concrete structures are increasingly vulnerable to deterioration by steel reinforcement corrosion, resulting in severe loss of fracture strength and service life, particularly in severe ...

The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.

An integrated framework for decoupling geodetic parameters in early seismic deformation monitoring: a case study of the 2011 MW 9.0 Tohoku earthquake

Geomatics, Natural Hazards & Risk
Accurate real-time monitoring of early seismic deformation using GNSS has long been limited by the coupling of multiple geodetic parameters, producing spurious co-seismic signals during the initial phase of earthquakes. Here, we present a full decoupling

Interpretive Structural Modeling and MICMAC Analysis for Identifying and Benchmarking Significant Factors of Seismic Soil Liquefaction

Applied Sciences, 2019
Seismic soil liquefaction is considered as one of the most complex geotechnical earthquake engineering problems owing to the uncertainty and complexity involved in soil parameters, seismic parameters, and site condition factors.

INFLUENCE OF GROUND MOTION PARAMETERS ON SEISMIC RESPONSE

Conference proceedings (Croatian Conference on Earthquake Engineering)
To establish a connection with structural vulnerability, ground motions generate intricate datasets distinguished by various properties. The objective of the investigation is to evaluate the impact of specific seismic record properties on the nonlinear structural response of buildings, with the ultimate goal of determining the characteristics that ...

Evaluation of the Adequacy of Design Specifications for Nonstructural Components in a Reticular Structure

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular

Parameter sensitivity in seismic net pay workflow

First Break, 2012
The objective of this paper is to illustrate the relative importance of the controlling factors in estimating seismic net pay from colour-inverted band-limited impedance data. It was achieved by using a new automated implementation of the process, allowing the sensitivity of each of the key controls on the resulting net pay to be found quickly and ...
