Electronic thermal sensor and Data Collection Platform technology: Part 5 in Thermal surveillance of active volcanoes using the Landsat-1 Data Collection System

Five Data Collection Platforms (DCP) were integrated electronically with thermall sensing systems, emplaced and operated in an analog mode at selected thermally significant volcanic and geothermal sites. The DCP's transmitted 3260 messages comprising 26,080 ambient, surface, and near-surface temperature records at an accuracy of ±1.15 °C for...

Kīlauea Volcano - Dark Ash Plume Rising from Overlook Crater

At 1:38 p.m. HST, another dark ash plume rose from the Overlook crater. During a flight earlier today by the Civil Air Patrol, the height of the ash plumes near the crater rose to more than 3 km (9,800 ft) above sea level, and downwind the plumes continued to rise to about 3.5 km (11,500 ft) above sea level.
