Haiti - FLASH : Increase of seismic activities in the Nippes
Engineer geologist Claude Prepetit, Director General of the BME, confirms that two simultaneous seismic shocks of magnitude between 2 and 3 were felt at Anse-à-Veau and Arnaud (Nippes) on Wednesday, August 16 at 3:10 am http://www.haitilibre.com/en/news-21840-haiti-news-zapping.html . Another 3-second slower shake was also recorded on Sunday, 20 August at 3:11 pm, as well as on 16 June at around 10:00 pm and at Jérémie on 13 June (intensity of 4.5 On the Richter scale) http://www.haitilibre.com/en/news-21290-haiti-flash-shake-4-5-in-haiti-update.html
He recalled that an earthquake of magnitude 6 which occurred on October 27, 1952 at 11:20 in the evening, followed by replicas until March 1953, had destroyed the town of Anse-à-Veau. 63 years later, the energies accumulated in the active faults of the region seem to be recovering from activity, 46 seismic events occurred in three months between 3 September 2015 and 4 January 2016. The tremor of Tuesday, October 13, 2015 occurred at 7:58 am was magnitude 4.06 on the Richter scale, it was located 4 km deep and its epicenter was located 9 km at sea north of the town of Anse-à-Veau.
Engineer Prepetit stresses that earthquakes are not predictable and can occur at any time. Consequently, faced of the seismic threat, preparatory actions remain and remain the norm: compliance with earthquake-resistant construction standards and behavioral learning before, during and after an earthquake.
