It’s been a week since the 6.2 earthquake in Costa Rica (Jan. 8, 2009) and while I’ve been updating my original post with info I thought I’d post another entry.

The death toll is at 23 people with 11 missing. Over 2000 people living in shelters and abut $100 million in estimated damages. This really sums up the whole tragic disaster.

There is a nice graphic of the area up at The Tico Times to give you some idea of location and details.

Speaking of The Tico Times, the latest issue came out today (it’s a weekly paper) and has a lot of information in it (they do sell a pdf of the paper on-line), they generally don’t publish very many full stories on-line other than by subscription but they’ve had a lot up there this week. The first 11 pages of the January 16, 2009 issue of the Tico Times is full of info on this earthquake, including a history of earthquakes in Costa Rica, info/diagrams of seismic plates in Central America a safety quiz and more. I’m not trying to sell you the TIco Times but it’s really got a lot on the earthquake this week and I do like The Tico Times.

I didn’t realize that this was the biggest quake in 18 years. Lately, I’ve heard mention of earthquakes, but I didn’t think I’ve heard much about them before a year or so ago. But I’ve spent more time there lately (4 trips in 12 months) and I’ve been getting The Tico Times delivered to Michigan so I’m catching more news that I would have missed before. I’m assuming it was my lack of information that led me to that misconception and not that they’ve had more in the past year.

There are volcanos in the area of the quake, the closest is the Poás Volcano which is about 10km from the center of the earthquake (about 90 km is the Arenal Volcano, the worlds most active volcano. Volcanos tend to follow fault lines and Costa Rica is right off of the one that becomes the San Andreas fault (if you follow it up a map you’ll see it). . Volcanos and earthquakes in the same place make me extra nervous but that doesn’t seem to have caused any issues. On a side note, the Poas Volcano National Park is closed through Monday due to some unrelated volcanic activity; it seems coincidental but maybe it closes all the time, but I haven’t noticed it in the paper before…

If you haven’t read it since I first put it up, I have added more links and news to my post from last week.

Costa Rica had a huge earthquake yesterday (Thursday, January 8th, 2009), 6.2 on the richter scale (I’ve seen reports that say 6.1). Just north of the San Jose area. This is the biggest one that I’ve heard of in Central Valley. The Tico Times has a lot of the earthquake coverage (you do have to do some clicking and scrolling, they’re mostly a subscription service).

They’re reporting about 23 dead with 11 still missing (at least that’s how I’m piecing everything together, I’ve seen numbers all over the place; as high as 30 dead). Lots of damage, mud slides and people trapped in various areas. 1,000+ people relocated and another 1,000+ stranded. If you check out the news stories from around the world there are definitely conflicting reports (especially on the death toll). Lots more earthquake details here and if you’ve got Google Earth installed there are some additional visual details if you click on the spot of the earthquake.

I can’t imagine the chaos and devastation that something like this causes. My thoughts an prayers go out to everyone affected by this…

I’ve been having a hard time getting my head around some of the damage, I found some photos at Inside Costa Rica and a video clip (in Spanish).

You can see many of the areas that felt it on this map, people can actually report it and that’s what feeds the map (don’t know how long they keep these on-line).

How many people are affected by this that I’ve met on my various trips down there? Places that I’ve visited or stayed at the I don’t recognize the names. I wonder how much it freaks out the tourists, imagine if they didn’t speak the language. I don’t speak Spanish well enough, in a crisis, without my translation book, I don’t know what I’d do…

There was a slightly bigger one (6.5 richter scale) in November when I was there, but I didn’t feel it and I don’t remember this much death and damage, but it was way at the south end of the country (I think it might have been in Panama) and if it was a few of my more isolated days I wouldn’t have gotten much news. My biggest earthquake ever was also in Costa Rica (4.3 richter scale) but most people didn’t even notice it (it was just after midnight).

A slightly erratic post but these thoughts have been in my head and wanted to share them…

I’ll add more links below:
Pictures from the Tico Times newspaper (more landscapes and buildings are towards the end).
Photos from al Dia from La Cinchona de Sarapiquí, Heredia
La Paz waterfalls had to close down. I believe some people took shelter there when the roads got cut off (I might be mixing the location up).

FYI, I’ve been updating the details in this posting daily, it was originally from January 9, 2009 but some of the details might be from up to a week later.

Something just happened. I’d say a huge semi-truck or two just drove by too fast and went through the crazy potholes (or something) but that’s not really possible where I am let alone it would have had to had been a 180 wheeled truck since it lasted a bit. It really shook the place for at least 4-5 seconds (it seemed much longer but I’m guessing it wasn’t) with a short ones a few seconds later about 22 or 23 minutes after midnight. Afterwards, it sounded like a few doors opened up at the hotel but no chatter of what might have happened. I don’t know how common earthquakes are here. I know I’ve never felt anything like it!

I’ve been looking on-line and finally found some data! It was a 4.3 Magnitude earthquake!!!! Not sure how big that is, but I’m from Michigan so…

The event id for this is “us2008wnan” as it’s official designation (I guess). This is the closest seismogram I could find from a drum recorder (are they still actually drums?) which happens to be the Volcano at Rincon de la Vieja, you can clearly see in the second block of 15 minutes after midnight the needle went a little crazy. Here’s some info on reading the seismograms.

Looking at the attached right-hand image (the “A” is the estimated center), I’m guessing it centered about 25-30 miles from here (Tamarindo). The smaller left-hand image has some time/date info with location info (and no other earthquake boxes for the last week in Costa Rica).

This was at 10.490°N, 85.851°W, a 4.3 magnitude and 39.7 miles (63.9 km) deep. Could this have been picked up as far os New Mexico or Oregon? Or were those coincidental marks on their graphs? Finding this I’m going to say “yes” (I found this in the morning).

I’ll keep adding data as I find it! It’s been two hours I’ve been collecting info, I’m off to bed, gotta get up in the morning to catch a flight.
