UPDATED 7:15 p. m. 

Alex Goldmark here with the night shift update. 

We've lined up our live reporter interviews from Chile for tomorrow morning. We'll get a sense of how the curfews and looting has unfolded as the hunt for water and gas gets more desperate in some areas. But we will stick with our plans to find out the science behind tsunamis and quakes and also the construction techniques that kept the death toll so low. 

Other than that, not much has changed, which means that here on the night shift we can get into long debates about the meaning of "999 dead in Operation Enduring Freedom." And should we consider a fallen CIA agent in Afghanistan differently than a troop killed in Somalia? Or across the Afghan border in Uzbekistan? It's all part of Operation Enduring Freedom so what's a radio show to do when covering "The War in Afghanistan."  Here's the official count from the DoD with little explanation on how the number is derived. We will hear from the mother of one of the first troops to be killed in Afghanistan on how she marks her loss eight years later.

POSTED 1:15 p.m. Anna Sale here on the day producing shift.

Tomorrow, we will continue our coverage of the earthquake in Chile. We'll hear the latest from reporters on the ground, and we'll also look at earthquake engineering and the role it played in averting fatalities. Strict building codes in Chile are getting much of the credit for containing the disaster. We're also following up on the weekend tsunami warnings — and the scary media coverage that went with them. We'll find out how tsunami forecasting works, and how scientists track fast-moving waves from the point of impact to the shoreline.

And in the next installment in the saga of Washington health care reform, we'll peer into the Senate rules in a segment we're calling "Budget Reconciliation: a History." How did the concept of majority rules became such a political hot potato in the United States Senate? As the White House is starting to signal support for the procedural measure (which Republicans brand a "political kamikaze mission"), we'll look back at the procedure's early days in the Nixon administration, how's it's been used in recent political history, and what's different about this attempt at overhauling the health care system.

It also occurred to us at our morning editorial meeting that one thing we find ourselves talking about  with almost every story in our morning editorial meeting, is numbers. The budget deficit, Richter scale readings, American casualties in Afghanistan. Tomorrow, we'll take a step back and look at whether numbers are good storytellers. What do they illuminate and when does turning to integers leave us cold. And we're asking listeners, What do you think? What gives you pause when you hear a story: A number that puts it in perspective, or a single image or word that brings it to life?

Finally, it's Oscar week, and we're looking back at "The Sound of Music," which was released 45 years ago and scooped the award Best Picture. We've lined up the actor who played Rolfe, along with a real-life member of the von Trappe family — Sam, the grandson of Maria von Trappe. If "The Sound of Music" is one of your favorite things (!), you won't want to miss it. Check back here later today, where you'll find a playlist of some of the film's classic songs, remixed.
