Volcano Watch: Electronic “doctor” tracks health of monitoring stations

  • A volcano-monitoring station "health monitor” developed by CJ Moniz at the Hawaiian Volcano Observatory. It consists of three programmable circuit boards (bottom row), voltage sensors (top row), a current sensor (top right corner), and a custom-made voltage sensor for a 48VDC system (tan circuit board on the bottom right). This unit is deployed in a watertight box to help the electronics withstand harsh environmental conditions. (USGS photo)

As part of Volcano Awareness Month earlier this year, Volcano Watch featured five articles focused on different roles at the USGS Hawaiian Volcano Observatory. These articles described the roles of geodesist, Scientist-in-Charge, gas geochemist, seismologist and geologist. This month, we continue that series, focusing on the role of technician.
