Characterization of thermal infrared medium- and short-term anomaly information from block to fault in mainland China

open access: yesFrontiers in Earth Science, 2023
The relationship between satellite thermal infrared anomalies and earthquakes or fault activity has been studied for more than 30 years. In this study, five strong earthquakes (the MS6.1 earthquake in Biru, Tibet; the MS7.4 earthquake in Madoi, Qinghai ...

The Sea-Level Changes in Hong Kong From Tide-Gauge Records and Remote Sensing Observations Over the Last Seven Decades

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The importance of studying the sea-level change (SLC) in Hong Kong (HK) is emphasized by factors related to high population density, intensive urban, and industrial development, particularly along the coast that involves a considerable landreclamation ...

Earthquake forecasting, public policy and earthquake forecasting

open access: yesBulletin of the New Zealand Society for Earthquake Engineering, 1979
The geodetic, geophysical and seismological approaches to earthquake forecasting are summarised and illustrated with examples of precursory phenomena, which can be categorised into long term, intermediate term, short term and imminent. The results from at least two, but preferably more, disciplines are needed to reliably identify a precursory phase ...

Probabilistic forecasting of earthquakes [PDF]

open access: yesGeophysical Journal International, 2000
We present long‐term and short‐term forecasts for magnitude 5.8 and larger earthquakes. We discuss a method for optimizing both procedures and testing their forecasting effectiveness using the likelihood function. Our forecasts are expressed as the rate density (that is, the probability per unit area and time) anywhere on the Earth.

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

DBA-RTMDet: A High-Precision and Real-Time Instance Segmentation Method for Identification of Damaged Buildings in Postearthquake UAV Imagery

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Unmanned aerial vehicle (UAV) remote sensing plays a crucial role in the rapid assessment of postearthquake-damaged buildings. Existing methods for automatic identification of damaged buildings based on UAV remote sensing imagery primarily focus on ...
