An undercurrent of seismic upheaval has been set in motion. Recent months have witnessed a subtle but discernible surge in seismic activities, an uptick, sending tremors of concern throughout the country. Are we on the brink of a major earthquake.

Upper-plate normal faults along forearcs often accumulate slip during > Mw 6 earthquakes. Such normal faults traverse the forearc of the Hellenic Subduction System (HSS) in Greece and are the focus of this study. Here, we use detailed field-mapping and analysis of high-resolution Digital Elevation Models (DEMs) to study 42 active normal faults on the islands of Kythira and Antikythira in the Aegean Sea. Onshore fault kinematic data are complemented by seabed bathymetry mapping of ten offshore faults that extend along the Kythira-Antikythira Strait (KAS). We find that normal faults in the KAS have lengths of ~1-58 km and scarps ranging in height from 1.5 m to 2.8 km, accommodating, during the Quaternary, trench-orthogonal (NE-SW) extension of ~2.46 ± 1.53 mm/a. Twenty-eight of these faults have ruptured since the Last Glacial Maximum, with their postglacial (16±2 ka) displacement rates (0.19-1.25 mm/a) exceeding their Quaternary (≤ 0.7-3 Ma) rates (0.03-0.37 mm/a) by more
difference and it ll be that much bigger. if a 7.8 on the san andreas will be a lot bigger. but consider this is only 10% of the san andreas so it s a pretty big earthquake. going from memory, though, the earthquake we had was like easter sunday. okay on easter sunday 2010, april 4th, a magnitude 7.2, i haven t been including that because it wasn t in california. the rupture was completely within mexico. so, yes, we felt it in probably a similar sort of distance well, it didn t feel quite as strong here. but it was not one of our fault systems. so when we re talking about earthquake rates, what s happening on the faults, i didn t include that. you talked about yesterday there s no way to forget if this
