Just keep an eye on the caldera to make sure the magma chamber isn't filling up and the ground rising. If the ground does being to rise at a fast
rate, it's a huge sign that thing may go kaboom.
Hmm, just wondering if you missed it. Samosir Island, yeah that big glob you see in the middle of lake Toba on the map in the OP, IS A RESURGENT MAGMA
DOME THAT HAS BEEN RISING STEADILY, with uplift of over 1,200 feet. There, hopefully that will get the message across.
That's why I don't like seeing shallow quakes anywhere near that thing.
And MamaJ, there could be all sorts of reasons data is not flowing, and I suspect the new IRIS Web Services as the likely culprit. They are still
implementing that new protocol, and probably fiddling with things. Other unrelated stations are out too, is why I say that. But this happens all the
time. If you are going to watch live seismic data, it goes with the territory: live with the constant down times. They are complicated networks, with
a whole lot of things in the telemetry that can go wrong.
Comprehending the sheer scale and size of that magma dome and caldera is difficult, but to give you an idea: just the magma dome itself (Samosir
Island) is nearly the size of the entire Yellowstone caldera. So the entire Toba caldera is actually much bigger than the Yellowstone caldera.
I mean look at this:
