Release of mineral-bound water prior to subduction tied to shallow seismogenic slip off Sumatra.

Plate-boundary fault rupture during the 2004 Sumatra-Andaman subduction earthquake extended closer to the trench than expected, increasing earthquake and tsunami size. International Ocean Discovery Program Expedition 362 sampled incoming sediments offshore northern Sumatra, revealing recent release of fresh water within the deep sediments. Thermal modeling links this freshening to amorphous silica dehydration driven by rapid burial-induced temperature increases in the past 9 million years.

[Results of an epidemiological survey conducted with psychiatrists, general practitioners, liberal nurses and social workers in a mental health sector].

An epidemiological survey was carried out, amongst psychiatrists, general practitioners, social workers and liberal nurses, with a double aim. To determine the number of psychiatric cases followed or identified; these were classified according to DSMIII criteria (simplified for use by those interviewers little used to psychiatric jargon), essentially: dementia, depression, schizophrenia, other psychosis, other cases (neurosis, substance abuse, alcoholism). Another aim was to determine how the psychiatric care facilities were perceived and used by the person's interviewed.
