Spatiotemporal Characteristics of Tectonic Tremors in California

open access: yesGeophysical Research Letters
California, as a transform plate boundary, provides a distinctive tectonic setting and an ideal natural laboratory for investigating tectonic tremors and the slow deformation associated with plate motion.

Modeling monthlong slow slip earthquakes [PDF]

open access: yesEos, Transactions American Geophysical Union, 2011
The slow crawl of the Earth's tectonic plates is periodically punctuated by the release of decades or centuries of accumulated stress. Standard earthquakes, lasting from fractions of a second to minutes in duration, are known to range from imperceptible to those that can flatten a city, but recent geodetic measurements have led to the discovery of a ...

Economic loss estimation for earthquake hazard in Istanbul [PDF]

open access: yes
Natural hazards, especially earthquakes, cause disasters when they hit large settlements such as metropolitan areas. After the first shock, the damage is counted by deaths and injuries.

Modeling fast and slow earthquakes at various scales

open access: yesProceedings of the Japan Academy, Series B, 2014
Earthquake sources represent dynamic rupture within rocky materials at depth and often can be modeled as propagating shear slip controlled by friction laws. These laws provide boundary conditions on fault planes embedded in elastic media. Recent developments in observation networks, laboratory experiments, and methods of data analysis have expanded our

A Brownian walk model for slow earthquakes [PDF]

open access: yesGeophysical Research Letters, 2008
Along some subduction plate boundaries, slow deformation is observable as seismically detected deep low‐frequency tremor and geodetically detected slow slip events. These phenomena are considered as different manifestations of slow earthquakes characterized by fairly constant seismic moment rate.

Hillslope memory and spatial and temporal distributions of earthquake-induced landslides [PDF]

open access: yes, 2013
Large earthquakes commonly trigger widespread and destructive landsliding. However, current approaches to modeling regional-scale landslide activity do not account for the temporal evolution of progressive failure in brittle hillslope materials ...

Seismic Vulnerability Assessment of Low-Rise Reinforced Concrete Buildings Affected by the 2015 Gorkha, Nepal, Earthquake

open access: yes, 2017
Low-rise reinforced concrete (RC) frames with brick masonry infill walls up to five stories high have been used for housing construction in Nepal since the late 1980s. Many buildings of this type were damaged and/or collapsed in the 25 April 2015 Gorkha

The 2010 MW 6.8 Yushu (Qinghai, China) earthquake: constraints provided by InSAR and body wave seismology [PDF]

open access: yes, 2011
By combining observations from satellite radar, body wave seismology and optical imagery, we have determined the fault segmentation and sequence of ruptures for the 2010 Mw 6.8 Yushu (China) earthquake. We have mapped the fault trace using displacements

Frontal Thrust Ramp‐Up and Slow Earthquakes Due To Underthrusting of Basement High in the Nankai Trough

open access: yesGeochemistry, Geophysics, Geosystems
Recently, integrated geophysical‐geological surveys in the Nankai subduction zone in Japan have revealed that slow earthquakes repeatedly occur beneath the outer wedge of the forearc.

Simulation of 2009, Mw=4 Tehran earthquake using a hybrid method of modal summation and finite difference

open access: yes, 2012
The Greater Tehran area is the most important city of Iran and hosts about 20% of the country population. Despite the presence of major faults and the occurrence of historical earthquakes, nowadays the seismicity is relatively quite low and this enhances
