The coast of Chile has been exposed to marine submersion events from storm surges, tsunamis and flooding due to heavy rains. We present evidence of these events using sedimentary records that cover the last 1000 years in the Pachingo wetland. Two sedimen...

Previous studies on the role of hurricanes in Mexico?s Gulf of California examined coastal boulder deposits (CBDs) eroded from limestone and rhyolite sea cliffs. Sedimentary and volcanic in origin, these lithotypes are less extensively expressed as rocky...

Geochronologies derived from sediment cores in coastal locations are often used to infer event bed characteristics such as deposit thicknesses and accumulation rates. Such studies commonly use naturally occurring, short-lived radioisotopes, such as Beryl...

A major flash flood took place in the Chacarilla catchment in January 2000 as indicated by offlapping overbank mudflow deposits. The peak flood has been determined at 450 (± 50) m3/s and it is possible to trace the origin of this flood to a quantifiable ...
