~Monitoring Equipment~
The United States Geologic Survey (USGS) team also arrived with seismometers, tiltmeters and other equipment to monitor any volcanic activity which included warning signs such as 10-150 earthquakes per day and increasing gas emissions with sulphur dioxide levels rising from 500 tonnes per day to 5000 tonnes per day in a period of 5 weeks.
