Peeking Within a Volcano Sensor

On a contemporary stroll throughout the Hawaii Volcanoes Nationwide Park, (*(*14*)*) stumbled upon an unlocked tracking station. Being an engineer, he couldn’t face up to having a look. This station is one of a community of sulfur dioxide (SO2) tracking stations put in across the park to regulate volcanic emissions. Unsurprisingly, sulfur dioxide is bad to respire. Sensors like those stay other folks knowledgeable about native prerequisites ahead of taking their strolls a few of the volcanic foothills, playing stunning vistas as [Andrew] describes it.


[Andrew] wasn’t specifically stunned on the contents of the station, since he builds identical apparatus in his day task. Steady energy is equipped by means of lead acid batteries saved charged by means of an array of three mis-matched sun panels. There are reproduction SO2 screens, an air particulate meter, and an ordinary climate station affixed to the highest. Information is logged on-site and reported up the chain by means of a cell-phone modem. [Andrew] wasn’t inspired with the workmanship, noting:

It gave the impression as though the circuits had been stressed by means of a ham-handed grad scholar without a sense of delight of their paintings.

Monitoring the atmospheric SO2 ranges close to volcanoes now not handiest is helping hikers and park rangers plan their out of doors actions. Gaseous emissions from volcanoes are one of plenty of measurements that geologists depend on to observe and expect volcanic process, as this comic strip from the USGS web site depicts.
