i'm interested in the same thing Steve. one thing
i am assuming is that there are separate infrastructures
for geological events, separated out from others like
telecommunications (long-distance phone on the seabed),
military and other hydrophones (i think for submarines),
and other antennas and wires. i know from electronics
that most things can be used as sensors, even a wire
across the ocean, to measure changes in resistance or
other things, and can be a way to sense or be alert
to changing conditions. so i wonder if the existing
nets across the ocean that are non-geological could
be put to use for monitoring such events somehow, as
a large integrated system for monitoring the ocean.
it is largely a mystery what is going on down there,
with technology. sort of like space-satellite realms.
here are a few stories i found...
Indonesian tsunami-monitoring system lacked basic equipment
Telephone line needed to relay warning signals was cut off in 2000.

'A seismograph designed to detect the earthquakes that cause tsunamis was installed on the Indonesian island of Java in 1996, but the data it collects is not sent to the central government in Jakarta because the telephone line has been disconnected since an office move in 2000.' .... 'Better-equipped warning systems elsewhere also failed to alert the relevant authorities. A network of seabed pressure sensors and seismographs, run by the United Nations, can detect Pacific Ocean tsunamis within minutes.'

Seismic 'megathrust' leaves islands displaced.

Sumatran quake sped up Earth's rotation // adjusting atomic clocks...
Natural disaster shaved millionths of a second off planet's day.

'The blast literally rocked the world on its axis, add Richard Gross and his NASA colleagues. They estimate that Earth now tilts by an extra 2.5 centimetres in the wake of the jolt.'
