9:45 PM | How to Stay Safe in an Earthquake – Napa Earthquake Reminds Us to Prepare Now
California residents in the Napa area got a rude awakening early this morning when an earthquake of roughly magnitude 6.0 shook the valley. It jolted folks awake (and jolted the already-awake folks)... -- Read more on ScientificAmerican.com

6:48 PM | Magnitude 6.0 Quake in Northern California - Largest Bay Area Quake in 25 Years
Source: http://www.data.scec.org/recenteqs/Northern California woke up this morning to the largest Bay Area earthquake since the 1989 Loma Prieta Earthquake (magnitude 6.9). The magnitude 6.0 quake, now being called the South Napa Earthquake, was located 6 miles (9 km) SSW of the wine country town of Napa at a depth of 6.6 miles (10.7 km). Dozens of people have been injured, three severely, and there has been a lot of structural damage, including a fire that destroyed at least four mobile […]

3:56 PM | Culling the deskcrops
If you saw my post for the Geological Society's "Speaking of Geoscience" blog, you'll know that I'm in a transition period - finishing up my job as a policy fellow and getting ready to move on to a postdoctoral fellowship with the USGS in September. In the meantime, that means I've been spending a lot of my time packing all my possessions into increasing numbers of boxes, in between pecking away at various writing projects.

3:04 PM | Why does anyone even care about the future?
The human community spans not only space but time. Naturally, we include in our community those closest to us--family and friends--and then in concentric circles of affiliation our co-workers; our fellow churchgoers (if we do that kind of thing); members of a civic group, a book club or a sports team to which we belong; the inhabitants of our town or city, of course; and our country. Some people even count themselves as citizens of the world.And, while we tend to reserve our deepest feelings […]

2:14 PM | Reclaimed water
I don’t know whether to view these signs all over Tucson’s golf courses proclaiming their use of “reclaimed” water as proud – “We’re water smart!” or defensive. But whenever the conversation veers toward water “reclamation”, always ask yourself where that water might have gone if you hadn’t, for example, put it on this golf course. ...Continue reading ‘Reclaimed water’ »

1:56 PM | Questions about the Gila Diversion
In the Colorado River Basin writ large, 14,000 acre feet of water is a very small rounding error – less than one tenth of one percent of the river’s flow. But the New Mexico discussion over the possibility of a diversion high in the watershed of the Gila River in New Mexico, raises fascinating questions ...Continue reading ‘Questions about the Gila Diversion’ »

7:28 AM | Northern Convergence: The Day We Actually Had on Vancouver Island...and Goldstream
A plan is such a wonderful thing! With a plan, one can conduct field trips smoothly, with no delays, no missed stops,  no problems. Oh, did I say plan? I meant to say "luck". I've been having fun with my recent posts, talking about the places on Vancouver Island that we intended to visit on our recent field studies course, but which we had to miss. There were plenty of reasons, all of the normal kind: it's all about what happens when you try to move 22 people from point A to point B.But we […]

12:08 AM | Geo 730: August 23, Day 600: Boulder Creek Boulder
Boulder Creek is a tributary to Quartzville Creek, just a bit upstream from the quarry. I don't have any photos of "the pyrite stop" (Yes, another one) up the road there, but I'll post a link to a nice 360 by 360 panorama sooner or later. I've always presumed Boulder Creek was named for this giant block at the confluence, and no one has ever told me differently. It's not easy to get a sense of scale here, but I'd estimate those two tree trunks to the boulder's lower left are in the range of […]

Walking up Mountain Boulevard in the Laundry Canyon area takes you through one of Oakland’s old mining and timber districts. (Laundry Canyon proper is under the Warren Freeway.)

9:23 PM | Geology Sonnet 6
Nobody studies fucking iodine. The halogen too rare for us to care, But iodate to carbonate’s inclined So we might have a useful proxy there. This IO3 requires oxygen, And thus does not exist in reduced seas. Its presence in old carbonates means then Ozone and oxygen were in the breeze. Archean carbonates do not have I, But it appears when O first graced the air. And thus another tool

9:16 PM | Mulroy: Lake Mead’s bathtub ring is not just Las Vegas’s problem
Former Southern Nevada water chief Pat Mulroy explains that, while Las Vegas is an easy rhetorical landing spot because it is right next door to Lake Mead, the dropping Colorado River reservoir is a basin wide issue: What we are experiencing is not a Las Vegas problem — it is truly a regional problem that ...Continue reading ‘Mulroy: Lake Mead’s bathtub ring is not just Las Vegas’s problem’ »

6:40 PM | Dirt Bucket Challange is a Bad Idea
Apparently, in the interest of saving water in drought-stricken California and calling attention to the crisis there, two men dumped dirt over their heads. This is a bad idea, in support of a good cause, in my view. The video has gone viral and shows a dry-land adaptation of the ALS Ice Bucket Challenge. Soil is not only where plants grow, but is also host to many kinds of bacteria …

4:28 PM | Reconstructing History
When you consider how much magmatic activity occurred in the Izu-Bonin-Mariana fore arc, the core from which we intend to gain so much historical geologic information may seem disproportionately small in comparison.  We collect cores no bigger than 60-62 mm (less than 2.5 inches) in diameter, which provide a very limited, but representative, view of the surrounding rock.  read more

3:45 PM | Mirror Lake, Bellingham Drinking Water and Phosphorus
Stopped by Mirror lake while on journey elsewhere. Mirror Lake is where water diverted from Middle Fork Nooksack River is discharged before it flows via Anderson Creek to Lake Whatcom, the drinking water source for Bellingham. The lake was in fully muddy mode from the diverted water that is derived from glacial melt water. Mirror LakeMirror Lake turbidityAerial view of diversion and pipe (blue line) (USGS)The City of Bellingham diverts water with a diversion dam on the Middle Fork Nooksack […]

11:17 AM | Possible eruption in Bárðarbunga volcano
This is early information and it might be wrong! Eruption might not be taking place and this might be a trick of magma movement underground. It is hard to be sure in this case until a visual confirmation … Continue reading →
