The need to speed up work on a reliable system for predicting potential aftershocks in the days following a strong earthquake has become more urgent, say US scientists, after a rare quake earlier this year was found to have triggered many large, and potentially damaging, earthquakes around the world.

Haiti’s cholera epidemic likely caused by weather

and has no comments yet.
Weather conditions — not UN soldiers — may have triggered Haiti's cholera epidemic, which has killed more than 1,000 people in less than a month, three leading researchers have told SciDev.Net. A coincidence of several catastrophic events — from climatic changes caused by the ocean-atmosphere phenomenon La Niña, to the plunge in water and sanitation quality following Haiti's disastrous January earthquake — provide the most likely explanation for the outbreak, which has hospitalised 17,000 people. The outbreak suddenly appeared in small communities along the Artibonite River, 60 miles north of the capital Port-au-Prince, on 21 October.
