I confirmed we can see them on kmst2

something earthquake was detected around 11:10 and 11:40 JST.

But they are not listed in the JMA earthquake list.

Nearby very small earthquake?

I'm developing a trigger to pick up Earthquakes from the SHINDO channels.

By applying the following requirements, Earthquake events look to be chosen well:

• the value is larger than a baseline (1-hour lowpass) +0.5
• time derivative is positive
• all seismometers show SHINDO > -6.5
• for the PSL ACC, all seismometers show SHINDO > -5

Most of the detected Earthquakes are not listed in the JMA alert.

For the triggered Earthquake events, good correlations for each channel are found.
So this algorithm is working well to distinguish Earthquakes from other local vibrations.

The EYV seismometer shows smaller than others?

I have updated the Earthquake monitoring page to the  Shindo-base information.
