What did we know about the electron mudflow before you started on this?
2:26
We knew the general dating of the electron mudflow and that it was one of many that has happened in the last 10,000 years.
2:34
There's been 50 or 60 of these mudflows in the last 10,000 years.
2:38
and there are multiple communities built on these mud flows.
2:41
About 1960s, there was some initial surveying that showed that these lahars occur, and the electron lahar was described as part of those initial surveys.
2:53
And subsequently, there had been radiocarbon dating that generally placed this electron flow about 1500 plus or minus 200 years.

So not a whole lot of accuracy.

Now that you know it's been 500 years since the last lahar, what does that say about the risk today for the area?
