A review and new insights on the estimation of the b-valueand its uncertainty
b-value seismology statistical methods synthetic-earthquake catalogs
2015/9/17
The estimation of the b-value of the Gutenberg-Richter Law and its uncertainty is crucial in seismic hazard studies,
as well as in verifying theoretical assertions, such as, for example, the universa...
Palaeomagnetic results from an archaeological site near Rome (Italy): new insights for tectonic rotation during the last 0.5 Myr
palaeomagnetism block rotation active tectonics Rome
2015/9/15
Approximately 20 km north-east of Rome, along the modern trace of the Tiburtina road, recent archaeological diggings have brought to light a system of aqueduct galleries constructed by Roman engineers...
