[1] Mud volcanoes sometimes respond to earthquakes, but the mechanisms by which earthquakes trigger changes in ongoing eruptions or initiate new eruptions are not completely understood. We measured gas discharge at a field of mud volcanoes near the Salton Sea, southern California, before and after the 4 April 2010 El Mayor‐Cucapah earthquake and observed an increase in gas flux immediately foll...

This study examines the effects of economic loss on the life satisfaction and mental health of Wenchuan earthquake survivors. Economic loss is measured by earthquake impacts on the income and houses of the survivors. The correlation analysis shows that earthquake impact on income is significantly correlated with life satisfaction and depression. The regression analyses indicate that earthquake ...

Our research focuses on computational techniques to understand the dynamics of space-time patterns in driven threshold systems, particularly on earthquake fault systems. We discuss the scientific and computational formulation of strategies for understanding such spacetime patterns, leading optimistically to earthquake forecasting and prediction. In particular, we describe pattern dynamics techn...

Earthquakes can cause tremendous loss of life and property yet predicting the behavior of earthquake fault systems is exceptionally difficult. The Earths crust is complex and earthquakes generate at depth, which is problematic for understanding earthquake fault behavior. Geodetic imaging observations of crustal deformation from Global Positioning System (GPS) and Interferometric Synthetic Apert...

The southeast offshore Mie earthquake occurred on April 1, 2016 near the rupture area of the 1944 Tonankai earthquake, where seismicity around the interface of the Philippine Sea plate had been very low until this earthquake. Since this earthquake occurred outside of seismic arrays, the focal mechanism and depth were not precisely constrained using a one-dimensional velocity model, as in a conv...

The 1985 prediction of a characteristic magnitude 6 Parkfield earthquake was unsuccessful, since no significant event occurred in the 95% time window (1985–1993) anywhere near Parkfield. The magnitude 6 earthquake near Parkfield in 2004 failed to satisfy the prediction not just because it was late; it also differed in character from the 1985 prediction and was expectable according to a simple n...

Presently, the modal pushover analysis procedure is extended to multidimensional analysis of structures subjected to multidimensional earthquake excitations. an improved multidimensional modal pushover analysis (IMMPA) method is presented in the paper in order to estimate the response demands of structures subjected to bidirectional earthquake excitations, in which the unidirectional earthquake...

This paper explores the effects of the 1995 Hanshin-Awaji Earthquake on the wages of people in the area of the earthquake over the 17 years after its occurrence and identified which part of the wage distribution has been most affected by this event by comparing the wage distributions of disaster victims and non-victims. To do this, we used three decomposition methods, developed by (i) Oaxaca (1...

Background: The 2008 Wenchuan earthquake triggered many rapid and long runout landslides, which directly caused great loss of property and human lives and were responsible for a large percentage of total damages caused by the earthquake. It is very important for the purposes of landslide disaster prevention and mitigation to understand the earthquake triggered mechanism of initiation and motion...

We study dynamic rupture propagation on flat faults using 2D plane strain models featuring strongly rate-weakening fault friction (in a rate-and-state framework) and off-fault Drucker–Prager viscoplasticity. Plastic deformation bounds stresses near the rupture front and limits slip velocities to ∼10 m=s, a bound expected to be independent of earthquake magnitude. As originally shown for rupture...
