There have also been seismologists from Seismic Research Unit, Trinidad, and visiting USGS seismologists. I don't know of any. Typically MVO record hundred of volcanic events each day, mostly rockfalls and long-period earthquakes.
Information is reported by seismologist to director, local government, media and public.
Real-time monitoring is a crucial part of MVO's operation. MVO does not produce any catalogs. MVO will move to a purpose built facility towards the end of 2001 and some changes to networks will have to made at that time.
