Real-time data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 4 hours. Recording and transmission times may be more frequent during critical events. Data from current sites are relayed to USGS offices via satellite, telephone, and/or radio and are available for viewing within 3 minutes of arrival.
