Here is the full skinny:
Mt Konocti is still dormant, but until recently, it was considered to be in a class of volcanoes very unlikely to go active (at least not during any of our lifetimes.)
Then Mt Konocti's "sister volcano" in Chile erupted, back in 2012, with only some months of warning. (or maybe it was six weeks?)
Like Konocti, the last time this volcano erupted was some 10,ooo to 12,ooo years ago.
Due to Konocti's resemblance to the other volcano, these days the volcano experts feel that Mt Konocti is just as unpredictable.
It is still sitting there, very peaceful, and technically dormant. However, due to how it resembles the South American volcano, the US Geological Survey people have come in and placed various sensors along Konocti's shoulders. This means that should it become active, people up here would have about six months of warnings. In theory anyway.
So this puts us exactly with the people in the SF Bay area. The big one could hit tomorrow, or in three months, or in two hundred years. For those in San Francisco area, it will be an earthquake; for us it could be a volcano coming to life. However, due to the volcano sensors, those of us in Lake County get to have a lot more warning than those in the Bay area. (Some earthquake sensor program here in the USA, offered up a ten second warning for Sunday's 3 Am quake. Not really much of a warning!)
I live about a twenty minute drive from Clearlake, and I can walk to Clear Lake the lake as it is only four or five blocks from my house.
(The first time I ever had any concerns about Konocti was one night when watching a movie about Pompei erupting in 70Ad or so in italy. And the matte paintings used to represent Pompei in the movie were so eerily similar to the silhouette of Konocti that I pointed it out to my husband. He was like, "I am not sure that this is a historical or geologically accurate picture of Pompei." But I guess now that it might have been accurate!)
