El Salvador’s geological service, the Servicio Nacional de Estudios Territoriales (SNET), issued a special bulletin on 10 July reporting that the seismic activity recently observed at San Miguel volcano (known locally as Chaparrastique) was ‘showing a tendency towards decline':
Yesterday, 9 July 2009, the microseismicity at the volcano declined to a daily average of 147 units RSAM. Today [10 July 2009], up to 15:00, the seismic stations have registered a daily average of 116 units. If this is compared to the values of previous days it can be seen that there is a tendency towards decline. It is important to note that the seismic energy of the volcano normally fluctuates between 30 and 50 units RSAM.
SNET is continuing to monitor the situation closely, and for the moment security measures, including a 2-kilometre-radius exclusion zone around the summit of the volcano, are remaining in force.
