F Market to the Castro

F MARKET | CASTRO

“F this train! (Don’t worry, it’s all cool.)” – January 3rd, 2011

Even when I’m otherwise pissed off at SF Muni, the F line always pulls through. It’s one of my favorite ways to travel through the city — the historic cars, the old seats, and the awesome growl of the train as it travels down the tracks. It’s not the quickest, but it’s fun!

Earthquakes in 2010 – A final update

Back in March of 2010, I wrote a post looking at the frequency of earthquakes occurring around the world and examined whether or not there were more earthquakes occuring than normal. Specifically, I chose to look at earthquakes between M6.0 and M6.9, as they are sufficiently large enough to be detected by seismometers around the world and they seem to be well documented in recent history.

So, what were the final numbers for 2010? Using the global earthquake search tool on the USGS website, we can see that there were 151 M6.0 – M6.9 earthquakes detected last year.

FILE CREATED: Mon Jan 3 19:59:37 2011
Global Search Earthquakes = 151
Catalog Used: PDE
Date Range: 2010/01/01 to 2010/12/31
Magnitude Range: 6.0 – 6.9
Data Selection: Historical & Preliminary Data

According to recent USGS data, an average of ~134 earthquakes happen in this range every year. Yes, we had 151, but does that mean it’s time to freak out?

No!

It falls well within what we would expect. In fact, there were more earthquakes within this magnitude range in 2007 (178) and 2008 (178)! What? Crazy!

A few more data points:
M7.0 – M7.9 eq’s in 2010: 21 (avg: ~17)
M8.0 – M8.9 eq’s in 2010: 1 (avg: ~1)

Here’s a handy table from the USGS [via]:

So, to sum things up, the world is not ending, despite what crazy folks say, earthquakes are not increasing, and there’s probably a number of other things more important to worry about.

Cheers and happy new year!

Succumbing to hypothermia

Volcanology Class - Hiking up Obsidian Dome

I recently stumbled across a 1997 article from Outside Magazine on what it’s like to freeze to death. Can’t say that it sounds too enjoyable.

At 85 degrees (core body temperature), those freezing to death, in a strange, anguished paroxysm, often rip off their clothes. This phenomenon, known as paradoxical undressing, is common enough that urban hypothermia victims are sometimes initially diagnosed as victims of sexual assault. Though researchers are uncertain of the cause, the most logical explanation is that shortly before loss of consciousness, the constricted blood vessels near the body’s surface suddenly dilate and produce a sensation of extreme heat against the skin.

All you know is that you’re burning. You claw off your shell and pile sweater and fling them away.

Gadget Survival Kit

GRID-IT - Gadget Kit

This is pretty brilliant! I picked one of these GRID-IT organizers up today thanks to this LifeHacker post.

These are all things that are floating around in my bag anyway (and cluttering things up), so it’s nice to finally have a way to organize them!

So, what do we have here?

  • iPhone USB cable
  • iPhone power brick
  • micro USB cable
  • mini USB cable
  • iPad camera connection kit
  • USB flash drive (16GB)
  • Transcend multicard reader

Now I just need a way to easily keep track of one of my various cameras, and I’m all set!

Drunken shark killer

Speaking of people with large balls, a drunken Serbian man killed a shark by jumping on its head.

“Dragan climbed on the jumping board, told me to hold his beer and simply ran to jump. There was no time for me to react or to try to stop him, he just went for it” says Milovan. “Dragan jumped high and plunged down to the sea, but didn’t make as much splash as we thought he would”, explained Milovan.

The reason could be because Dragan Stevic ended up jumping straight on the shark which was lurking near the beach, probably looking for its next victim. Dragan had nailed it right in the head, killing it instantly. The Egyptian police found the shark washed out on the beach that morning.

Dragan was able to swim to the shore and told his friends he had twisted his ankle, telling them the water was not that soft. The water is soft buddy, you just landed on a shark. At the moment, the fearless hero is in a hospital recovering from alcohol poisoning. After Dragan gets well, he will get a chance to have some more drinks as the resort had awarded the Serb tourist with a free vacation for his heroic deed.

Part of me thinks this is some sort of fake story, but part of me really, really wants it to be true.
