永乐国际 Recent high-quality seismic and geodetic observations provide large volumes of data, which enable accurate determination of earthquake source parameters, including locations, magnitudes, moment tensors, and detailed imaging of coseismic rupture processes. Further, various techniques for solving forward and inverse problems have improved substantially in the recent past. Abundant information from these analyses is the basis for studying a variety of earthquakes including catastrophic earthquakes, medium to small earthquakes, slow earthquakes, swarms, tectonic and volcanic events as well as induced events, and to seek the governing laws and conditions for rupture initiation, growth and arrest. It also provides useful input to estimate the stress state, fault geometry, and fluid movement around seismic regions. The entire earthquake process from long-term tectonic loading and slow nucleation to rapid rupture propagation with strong motion radiation is now studied using numerical simulations. The validity of assumptions in these simulations is tested by data analysis and laboratory experiments supported by several drilling projects. The topics of interest include, but are not limited to, the following:
永乐国际In symposia in IASPEI meeting, we invite contributions on data analysis and interpretation of earthquake parameters and source processes, on improvement and validation of routine analysis techniques, on theoretical and numerical modeling of dynamic ruptures and earthquake sequences, and observational and experimental studies on the physics of earthquakes. Studies of recent significant earthquakes are always important. We welcome contributions on various study regions in different tectonic environment from diverse countries, and also encourage the presentations by young researchers.
