A 6.0 magnitude earthquake that rattled Napa and surrounding communities early Sunday morning was the largest to hit the Bay Area since the devastating 6.9 Loma Prieta quake in 1989. The South Napa Earthquake, as it’s being called, struck at 3:20 a.m., causing significant damage and injuries in the immediate vicinity and waking folks up as far south as Salinas and as far north as Ukiah.

As of Monday morning, USGS scientists still hadn’t confirmed the specific fault line where the quake occurred, although the likeliest culprit is the Browns Valley section of the West Napa fault, one of the many fault lines comprising the sprawling San Andreas Fault system.

Relative calm seems to have been restored in the St. Louis suburb of Ferguson, Mo, where the death of Michael Brown, an unarmed 18-year-old black male shot by a white police officer, sparked nearly two weeks of fierce protest and rioting. But the underlying racial and economic tensions in the community that helped create such a powder keg have not gone away. And with increasing poverty in a growing number of suburban communities across the country — including several in the Bay Area — Ferguson’s issues certainly aren’t unique.

What You Need to Know about Immigration Reform [An Animated Explainer]

Remember when U.S. immigration reform seemed like it was finally in the cards?

That was so 2013.

The brief burst of fanfare following passage of the Senate’s comprehensive bill last year faded quickly when the debate hit the bitterly divided House, where prospects for getting anything done have now been all but extinguished. Continue reading

Four Multimedia Resources that Shed Some Light on the Israeli-Palestinian Conflict

The Israeli-Palestinian conflict erupted again in early July after the bodies of three Israeli youth turned up in Palestinian territory. It’s the most deadly face-off  between Israel and the Hamas-controlled Gaza Strip since the last series of rocket attacks in 2009.

The saga seems infinite: tenuous periods of calm punctuated by spates of extreme violence and desperation. At the most basic level, the struggle is over a slice of territory not much bigger than New Jersey, to which both sides claim ownership. But the roots of the conflict are deep and tangled, mired in complex issues of identity and displacement dating back to World War I. In examining the current situation in context, these four unbiased resources offer clues to why peace in this region remains so stubbornly elusive. Continue reading

Click on different points on the map below to see which counties would be part of each one of California’s six new states, as outlined in a proposed ballot initiative. Per capita income and population figures are listed for each “state,” based on an analysis by the California Legislative Analyst’s Office.

Think California’s just too darn big for its own good? Well now there’s a strong likelihood you’ll get to vote on it.

A Silicon Valley venture capitalist today submitted what he claims are enough petition signatures to get his initiative, to split California into six states, on the 2016 statewide ballot.

And no, this is not a joke. Continue reading

The Supreme Court this week dealt a blow to the nation’s struggling labor unions. In a 5-4 decision along  ideological lines, the court ruled that some government workers who decline membership in the unions that represent them can’t be forced to pay collective bargaining fees.

Just over 11 percent of the U.S. workforce belongs to a union today, the lowest rate in more than 70 years.  Continue reading

World Cup Basics Explained Really Fast (Including the Slack Rules of Stoppage Time)

Includes video and interactive map

Correction: Several readers astutely pointed out that the map below of qualifying teams in the 2014 World Cup had inaccurately labeled Scotland, Wales and Northern Ireland as part of the English national team. Big faux pas! While part of Great Britain, these three are undoubtedly distinct from England — which has already been ousted from the tournament. Each have their own national teams (none qualified for the Cup this year), and for reasons of historic and cultural rivalry, often support England’s opponents. The map’s boundaries have been updated accordingly. And to all you Scots, Welsh and residents of Northern Ireland (and their die-hard fans): mea culpa.
