There's a wunderground feed from the Diori Hamani International Airport at
lat/long 13.4, 2.2, but is doesn't seem to have barometric pressure history.
I put in approxiamte antipodal lat/long of (20.54, 4.7) and it calculate
arrivals as:
distance to eruption 20002.7 km
arrival at 1642282593 (202
I made a mistake (wrong sign) on longitude, here is the correct graph with
better correlation for the three peaks.

Check early morning Jan 16, when the wave came the opposite direction.
Might of capture that wave. They say the second wave was stronger on the
east coast.

I did the same, since by the time I looked it had disappeared from the
daily plot.
I am 3300km from the volcano (East coast Australia).
Unfortunately my station only updates the barometer value every 15 minutes,
so there is only a single point at the "peak", a value back around average,
then the

It's easy, but then you get to play with awk to get what you really
want.
sqlite3 weewx.sdb "select dateTime, barometer, altimeter, pressure from
archive order by dateTime;"

It may be that the first wave came through much earlier than I have a
graph available. My graphs from the daily view has scrolled past the
point where anything around 1400 to 1500z 15 Jan can no longer be seen.
There is probably some way to query the DB on the WeeWX server to tease
this data out
Fascinating observations!It would be very nice to have the precises
coordonates for all stations.
Included is a very preliminary plot of the two events. I suspect we can
find other "reverberations".
My coordonates are 46:22:50 N / 6:13:31 E / 410 m (Nyon in Switzerland)..

Interesting! I immediately looked into my records and - yeah - it's there,

Looking at the past 24 hours there is an interesting "wave" shown just
after midnight (0600 UTC) here. What time did it occur? News reports
refer to "local time" but make no mention of UTC.
