Are any public-reported earthquake precursors valid?
This article examines retrospective publicsupplied precursor reports statistically, and confirms published hypotheses that some alleged precursors within 100 km and within a day prior to the large 1995 Kobe and 1999 Izmit earthquakes, may be valid. The confirmations are mostly at the p<0.001 level of significance. Most significant were alleged meteorological and geophysical precursors, and less...
متن کاملFrog Swarms: Earthquake Precursors or False Alarms?
In short-term earthquake risk forecasting, the avoidance of false alarms is of utmost importance to preclude the possibility of unnecessary panic among populations in seismic hazard areas. Unusual animal behaviour prior to earthquakes has been reported for millennia but has rarely been scientifically documented. Recently large migrations or unusual behaviour of amphibians have been linked to la...
متن کاملPossible earthquake precursors revealed by LF radio signals
Among radio signals, low frequency (LF) radio signals lie in the band between 30–300 kHz. Monitoring equipment with the ability to measure the electric strength of such signals at field sites, were designed and assembled in Italy. From 1993 onwards, the electric field strength of the MCO (216 kHz, France) broadcasting station has been collecting measurements at two sites in central Italy that w...
متن کاملForever Young
Propagation of a species requires periodic cell renewal to avoid clonal senescence. Liu et al. (2010) now describe a new mechanism of cell renewal in budding yeast, in which damaged protein aggregates are transported out of the daughter buds along actin cables to preserve youthfulness.
متن کاملRevision Forever!
Revision is a method to deal with non-monotonic processes. It has been used in theory of truth an an answer to semantic paradoxes as the liar, but the idea is universal and resurfaces in many areas of logic and applications of logic. In this survey, we describe the general idea in the framework of pointer semantics and point out that beyond the formal semantics given by Gupta and Belnap, the pr...
