Two new CIEN stations have been recently installed in the Umbria Region: in Avigliano Umbro and Città di Castello. These two new stations have same features as the nine preexisting stations. So, currently there are 11 stations continuously recording electric fields, see Fig. 1. The two new stations had already been activated by July 21, 2013, when a strong earthquake, M w = 5, struck in the Adriatic Sea a few kilometers from the shore under Monte Conero near the city of Ancona. The monitored electric signals ranged from ELF (4 Hz – 1 kHz) to LF (25 kHz – 100 kHz) bands (Fidani, 2011). Three stations were not recording at that time: Siena, Città di Castello and Capitignano. According to reports received by EMSC, the main shock occurred at 01:32 UTC (local time Sunday, July 21, 2013 at 03:32) and lasted for 10-20 seconds. The depth of the shock was reported as 5 km, near the villages of Numana and Sirolo, Ancona Province. No damage or injury was reported. Two probable macro anomalies were collected from the population. One earthquake light (Fidani, 2010) was observed hours before the shock by two witnesses. It was reported as a ball of light positioned toward the south, at about 00:00-00:30 LT 21 July 2013. That morning, the witnesses were traveling by car from the south of Ancona towards Loreto along the highway when they saw a light from behind a hill in the west. It was bigger than a 66 GNGTS 2013 S essione 2.1
