Seismology offers the highest-resolution view of mantle structure. In the decades since Morgan [1971] first proposed deep-mantle plumes, seismologists have used increasingly sophisticated methods to look for evidence of such structures, but so far they have had little success. This abstract outlines the relevant seismological methods for non-specialists and summarizes the current state of knowl...

We present the architecture of a so-called Seismic Data Management and Mining System (SDMMS) for quick and easy data collection, processing, and visualization. The proposed SDMMS architecture includes, among others, a seismological database for efficient and effective querying and a seismological data warehouse for OLAP analysis and data mining. We provide template schemes for these two compone...

by producing undistorted three-dimensional images of the area under examination, cone-beam computed tomography (cbct) systems have met many of the limitations of conventional radiography. these systems produce images with small field of view at low radiation doses with adequate spatial resolution that are suitable for many applications in endodontics from diagnosis to treatment and follow-up. t...

Stress inversion of seismological datasets became an essential tool to retrieve the stress field of active tectonics and volcanic areas. In particular, in volcanic areas, it is able to put constrains on volcano-tectonics and in general in a better understanding of the volcano dynamics. During the last decades, a wide range of stress inversion techniques has been proposed, some of them specifica...

This paper presents the strategy and operational tools developed and implemented at the Euro-Mediterranean Seismological Centre (EMSC) to detect and diagnose the impact of global earthquakes within minutes by combining « flashsourcing » (real time monitoring of website traffic) with social media monitoring and crowdsourcing. This approach serves both the seismological community and the public a...
