Volcanology Scientists Stay Safe with Remote Sensors
Natural disasters can be massive and problematic. For those individuals who are economically, politically, educationally, or technologically impeded, they can be absolutely devastating. Vulcanologists can attempt to anticipate eruptions by observing the conditions in and around a volcano, normally with a variety of sensors. The sensors and equipment measure the gases for composition, the size and number of earthquakes, ground temperature, bulging of the earth around a volcano and deep location of the magma beneath the volcano. Sensors can also measure the viscosity of the lava which saves lives by using the viscosity test to find out how fast the lava flow is, The temperature changes the thickness of magma.
Generally sensors were all hand deployed, putting researchers and vulcanologists at danger while being used. Today advances in solar powered and Ethernet Extension technology, these sensors can now be deployed long term and more of them to cover more area of a volcano all at the same time. This gives key ongoing critical data at a remote safe distance to experts that can more effectively interpret the data and better predict disastrous events.
Ethernet and PoE Extender Uses for Scientists
Since 2006 one of our US Government customers – the U.S. Geological Survey at the Hawaiian Volcano Observatory (HVO) has been using Ethernet Extenders with Remote-Controlled Pan, Tilt, Zoom Cameras at Kīlauea and Mauna Loa Volcanoes, Hawai‘i
The Kīlauea caldera system has been in an active eruption since 1983 and scientists studying the Kīlauea volcano from the air and the ground have had to contend with hazardous plumes of sulfur dioxide gas that are streaming from the fissure in the ground that opened up on the Holuhraun lava field, like a scrape on a person’s skin. The gases may pose a health hazard to populated areas downwind of the eruption, and have been detected as far away as Norway. The scientists are still unsure exactly how the eruption will proceed from here. It could eventually result in flooding or an ash-producing eruption that would disrupt trans-Atlantic air travel and, if it is large enough, exert a cooling influence in the Earth’s climate.
Volcanic hazards sensors focus includes slope stabilities, landslides, debris flows, droughts, and floods—and their impact on community development, transportation, health, sanitation, and water quality. PoE and Ethernet extenders are currently in use with the following too to help enable remote sensors.
Seismic remote sensing – monitoring and measurement of earth movements including GPS, IP Camera video and laser toolsets.
Atmospheric Remote Sensing – monitoring and measurement of volcanic cloud detection and tracking of SO2 in the atmosphere.
Thermal remote sensing – monitoring and measurement of vents and general are heat detection.
Volcanic hazards communications is crucial in analyzing real time data from these remote Ethernet and PoE enabled sensors.
