Replying to @rtvutrecht
Dit filmpje laat de geluidsgolven zien/horen die bij het @KNMI in De Bilt (afstand ~3.5 km) zijn gemeten. In het filmpje is het geluid vijf keer versneld om de lage frequenties beter hoorbaar te maken. Het sterkste signaal komt rond 22:52:29 aan, ~11 seconden na de inslag.

Yesterday's eruption of #MaunaLoa was detected at infrasound array I59US (part of @CTBTO's International Monitoring System) at ~33 km. Continuous infrasound is detected starting around 09:23 UTC.

🚨🌋 New #SeismoBlogPost out! Remember the Tonga volcano eruption from earlier this year? Here @jdassink from @KNMI walks us through some of the atmospheric and seismic observations following the climactic event. Check it out!👇 @EuroGeosciences blogs.egu.eu/divisions/sm/20…

Global seismoacoustic waves from the Hunga eruption (Tonga)

Jelle Assink, Senior Geophysicist at KNMI, takes us through the details of the various kinds of waves produced by the Hunga eruption in Tonga earlier this year… On January 15, 2022, a powerful...

Gletsjers zijn de laatste jaren vaker geluid gaan maken. Het gaat om onhoorbaar geluid: infrageluid. Dit blijkt uit 18 jaar lang metingen op Groenland. Hiermee komen we meer te weten over het veranderend gedrag van gletsjers onder klimaatverandering. knmi.nl/over-het-knmi/nieuws…

Recent activity at #HungaTonga has been detected at several #infrasound arrays of the @CTBTO IMS infrasound network. The array at 1850 km distance measured an extremely large pressure pulse following today's activity. It was so large that even the barometer measured it. @KNMI
