Influence of sea-floor spreading on the global hydrothermal vent fauna
Article Abstract:
The development of Mesozoic and Tertiary mid-ocean ridges had a significant influence on the patterns of hydrothermal vent fauna. Primary migration pathways occur through the mid-ocean ridges. The taxonomic similarities represent distance along the ridge system and the primary irregularity produced by the San Andreas Fault. A trans-Pacific ridge pathway present during the early Cenozoic and the kula-Pacific ridge facilitated an east-west connection along the north Pacific until 55 Myr ago.

Effect of slab temperature on deep-earthquake aftershock productivity and magnitude-frequency relations
Article Abstract:
The vertical velocity and age of the subducting lithosphere reveal that the temperature of the downgoing slab determine the aftershock productivity and magnitude-frequency relations of a deep earthquake. Deep earthquakes in warm slabs show fewer aftershocks than deep earthquakes in cold slabs. The magnitude-frequency relations also vary with warmer slabs showing fewer small earthquakes than colder slabs. This temperature sensitivity of deep earthquakes is absent in shallow earthquakes.

Long-term eruptive activity at a submarine arc volcano
Article Abstract:
Direct observations and sampling of an eruption at a submarine arc volcano named NW Rota-1, located 60km northwest of the island of Rota is described. A pulsating plume permeated with droplets of molten sulphur disgorging volcanic ash and lapilli from a 15-m diameter pit in March 2004 and again in October 2005 near the summit of the volcano at a water depth of 555 m is observed.
