Citizen Science and the Tonga Eruption #Science #Tonga
A number of people heard about the Tongan volcano eruption and grabbed their Raspberry Pi and pressure sensors and recorded the pressure wave that swept around the planet.
Köln-Wetter posts: “Overview of Pressure of the volcano eruption in Tonga for Cologne. Shown: change in air pressure per 10 minutes.” (graph above)
Claudio Kuenzler posts: “Just looked that up, and to my huge surprise, even my small Bosch Adafruit BME680 sensor, connected to a Raspberry Pi 3B+ was able to catch the Tonga explosion wave!!! Stored in an Influx DB, graphs made with grafana.”
Sandy Macdonald posts: “The Tonga volcanic eruption pressure shockwave measured on a hastily set up Pimoroni BME280 sensor and Raspberry Pi in York, UK. That’s 16,270 km away, and taking 14h 20m to get here gives a speed of 1,135 km/h or 315 m/s!”
