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 KA...

New fault zones could impact Seaport Village redevelopment plans and last updated 2021-02-26 20:35:26-05 SAN DIEGO (KGTV) - A new proposed geological map could spell trouble for San Diego developers. A new map released by the California Geological Survey fills in the gaps for the Rose Canyon Fault, which runs from La Jolla and splinters downtown through the airport and Seaport Village. The colored zones indicate where an earthquake could happen. "Mother Nature got there first and now we have to accommodate for her," Geologist Dr. Pat Abbott said. He said the fault last moved about 300 years a...

It is a great opportunity. >> a great opportunity because it does appear there has not been any casualties or major injuries. 6.4 may sound to somebody outside of california very large. how would you describe what that feels like? >> for me, it felt like the ground was shaking for 20 seconds under my feet. if you are closer, obviously the shaking is much, much stronger. if it happens under old brick buildings, it could easily knock them down. that's the size of the earthquake. >> dr. lucy jones was saying this actually involved two faults. can you explain that to us? >> yes. this is a part of ...

Earthquake of this magnitude? why are some parts of the world considered to be at a greater threat for earthquakes? how does an earthquake cause a tsunami? kate hut. is a geologist. she joins us. good afternoon, kate. >> yes, hello. >> let's start with -- >> i'm with cal tech. i'm not with the usgs. >> so sorry. that was my mistake. >> an earthquake is a result of a long time period where strain or deformation accumulates in the crust until the rock in the fault zone can't take the strain anymore and it breaks. and that sudden motion releases all of the energy that has been stored up over that...
