Appendix 2

This appendix summarizes the macroseismic effects of the Villebourg-Gouraya
earthquake as reported in the original and contemporaneous sources cited in the
text.
On 15 January 1891, at 3 h 55 min, a destructive earthquake struck the local-
ity of Gouraya and its surroundings villages. The epicentral area, which is centred
between Gouraya and Villebourg (Larhat nowadays, a village of the Gouraya com-
mune), is located at 110 km west of the capital Algiers. Two shocks were felt in
the time span of 10 min and the earthquake was strong enough to awake people
and caused great panic in the coastal zone of Tenes-Algiers. The whole population
of Gouraya, was evacuated and camped in the streets. Many people of Algiers fled
their homes and as reported 500 crowded to the Government square. Two Europeans
and 37 native persons were killed, buried under the ruins of their traditional houses,
