Googling the Tsunami

More from Google Trends, the sad rise and fall in our interest in the tsunami: At the end of 2004, the Asian Tsunami piqued/peaked our attention, but the later blips (F, the last little flag on the chart, is the first anniversay) reflect, perhaps, how quickly such things are forgotten.

What Early Groomers Used For Hair Gel

I don’t use hair gel anymore — no, really — but I do remember wandering around war-torn Kabul trying to find some when my stash ran out during an unexpectedly long stint there shortly after the Taleban takeover. Needless to say I felt somewhat superficial about it, given all the suffering around me, and was worried it was frowned upon by the puritanical Taleban. I shouldn’t have worried: most of them wore eyeliner, took way too much interest in my babyish features and in any case, there’s a long history of wearing hair gel, as National Geographic News reports:

Male grooming has an ancient history in Ireland, if the savagely murdered bodies of two ancient “bog men” are anything to go by. One shows the first known example of Iron Age hair gel, experts say. The other wore manicured nails and stood 6 feet 6 inches tall.

Disappointingly, you have to look elsewhere to find out what kind of hair gel. I personally like Slick from Body Shop, but it might not have been available then, namely between about 400 BC and 200 BC. Another piece from National Geographic, suitably titled ‘Iron Age “Bog Man” Used Imported Hair Gel’ details the product he was using:

The man’s hair contains a substance made from vegetable oil mixed with resin from pine trees found in Spain and southwest France. The man might have used the product, researchers say, to make himself appear taller.

Sounds like my friend John.

Earthquakes, Power Laws and Sparklines

The Asian tsunami, and the quake near Nias, bring home how volatile the region is, particularly Indonesia. (Another quake this morning sent Nias residents fleeing into the hills in panic.) But I thought an interesting way of illustrating this volatility might be to do a sparkline of earthquakes and their magnitude around the world in the last week, highlighting those in Indonesia (most, but not only, around Sumatra) in orange:

Of course, it would be better to show their depth as well, but the sparklines tool I’m using, the excellent SparkMaker from Bissantz, is not yet up to the task. Data is from the USGS Earthquakes Hazards Program.

That’s more than 140 quakes in a week, more than half of them in Indonesia. And each one is of a size not to sneeze at, obeying, I guess the power law that, according to John Gribbin in Deep Simplicity, determines there is no single trigger for a major earthquake: An earthquake of any size is governed by the same rules. (This implies that another tsunami is not necessarily a long way off, just because there was one recently.) But if nothing else the sea of orange indicates how many Indonesians live in a state of almost permanent shock.
