Hi everyone, This is the first time I'm actually sending a message on this mailing list, so here goes. Since August 9th, the city of Bhavnagar has been experiencing an earthquake swarm. Two large events occured. One on August 13th (4.7Mb) and on September 12th (4.4ML). After yesterday's quake, steam and vapour was emitted from cracks that developed in the earth. I know that this phenomenon is not uncomman during and after earthquakes scientists are all saying that there could be volcanic activity in this region. One scientist from the NGRI attributed the quakes to "sea-floor spreading". The region being shaken is the western shore of Gulf of Khambat. It lies in the south-eastern part of the state of Gujarat, in western India. This region does have hot springs (mentioned just in case they bear any relation to volcanic activity). It is in a structure called the "Cambay Rift". It also lies in Indian Seismic Zone 4 making it vulnerable to earthquakes of magnitude 7. Could the part of a volcano be something worth following up on??? Or would this be a realy interesting seismic swarm???? REally confused here. Western India has had more than its share of quakes this year. Eight magnitude 4+ quakes have occured since March 2000, 3 of which were magnitude 5+ in Koyna (in the neighbouring state of Maharashtra). Yours seismically, Stacey S. Martin : ) __________________________________________________________ Public Seismic Network Mailing List (PSN-L)
