I have through a number of years of blackouts in Santiago and on the coast always found them up and running (dial tone which does not mean you will get through if the entire communication infrastructure is maxed), even had dial tone after the 8.3 (localized) quake.

Late last night/early morning because of the blackout, my pareja in Santiago could not get through to me on the coast via our Movistar cells (not even text messaging) but she could use that same Movistar cell to call my Telefonica/Movistar landline.

SO I have found the old copper based landline system ultra reliable in terms of being the last to go out and the first to be active after an "event."


Yeah, I have Movistar/Teléfonica for my landline and that has been the easiset method of communication when there were problems. Last night with the blackout my Entel and my husband's Movistar cell phones did not work, but a friend was able to get through to us, landline to landline. It was similar last Thurday with the aftershocks. I did have some problems getting through to the US on the 27th and vice versa, but I am guessing the system for international calls is overloaded.

If the system is that weakened, there recently was a CME that should reach earth around Wednesday.

These events have been linked to electric grid failures in the past (not to mention earthquakes).

So keep them candles, flashlights and batteries handy. My generator died on my bencina blanca Coleman lantern yesterday. :cry:

had to look that one up - Coronal Mass Ejections - aka - solar flares -

gee - aren't the earthquakes and tsunamis enough :roll:

Ask eeuunikkeiexpat about his special tin foil hat for such occasions (i.e. not the same as the one to be worn on normal days). There's a special rate for Allchile numbers, you would have to pay me a fortune to get me to part with mine!

Are you ready for more of the same...?
Better be?


(from WSJ)
UPDATE:Chile Power Grid Seen Unstable For A Week After Blackout

Chile's main power grid, which supplies electricity to about 90% of the population, will remain unstable for about a week following a blackout Sunday, President Sebastian Pinera said Monday.

He said the blackout, which resulted from a damaged transformer at one of the grid's substations, was a consequence of the massive earthquake that hit the country in late February.

"The blackout was undoubtedly linked to the Feb. 27 earthquake as it damaged the transformer" that burned out Sunday, Pinera said at an event inaugurating the school year.

The recently inaugurated president vowed that the damaged transformer would be repaired within 48 hours and that the transmission lines would be stabilized in a week.

"In the next seven days, we'll have a stabilized electricity system," Pinera said.

Chileans, already spooked by one of the strongest earthquakes on record and the hundreds of aftershocks that have continued to shake the country, found themselves in the dark Sunday night.

Power was restored slowly throughout the SIC grid and, by Monday morning, 98% of supply was reestablished, the country's National Emergency Office, or Onemi, said.

Energy Minister Ricardo Raineri, meanwhile, said he didn't rule out more blackouts as the SIC grid, which runs from the northern area of Tal-Tal to the southern island of Chiloe, is still vulnerable.

"It's possible, but for now we're asking everyone to help us out by using electricity moderately; until we can restore [grid] security, the situation will remain critical," Raineri told reporters.

The SIC grid has a gross installed capacity of about 9,400 megawatts, with 52% of that capacity coming from hydroelectric generators.


BTW... everything is just fine up here in Arica - no worries :D

Please no taunting from the far north. :mrgreen:

Seriously, far north is the only region of Chile left to experience a 80-100++ year MEGA quake. You guys should be preparing.

I wonder how much this will push the vote for the building of the mega dams in the south.

Blackout is first column news on Drudge... From Bloomberg

http://www.bloomberg.com/apps/news?pid= ... lrdVjnvBFk


“Things like this could happen in the future,” Energy Minister Ricardo Raineri told reporters in Santiago yesterday. “Recovering the systems is a difficult task” after the Feb. 27 quake, and there may be blackouts for “months,” he said.


Codelco, the world’s largest copper producer, said back-up systems were used in several of its mines during the power cut.


...now I'm adding "100% off the grid power" to the build an earthquake proof house list.......

It was power from the south as I understand it that caused the blackout. It was a central distribution station in the Bio-bio region that took out the whole grid. How about wave power? There does not seem to be shortage of that recently.

From the bloomberg article:

Pinera said he plans to rewrite the 2010 budget to free resources for a reconstruction fund. Chile has $11.3 billion invested overseas in an economic stabilization fund that the government can use to finance a budget deficit.


How many countries in the World have that on tap these days?

Here's official info (in English!) on the ESSF:
http://www.minhda.cl/english/fondos_sob ... _valor.php

Probably the best-managed commodity-driven economy in the world from a financial perspective. There's no public debt, a characteristic shared with only a few oil-flush states or tiny ones. We avoided the worst of Dutch Disease, but alas, there's also been a marked slowdown in diversification away from mining either the last 20 years (as a share of exports or GDP, copper dropped in the 70s/80s but no longer since then, lately not helped by high copper prices). I have a hard time understanding why copper needs to be shipped to China to be wrapped in plastic into an Ethernet cable before it's shipped back to Chile. At the very least, there should be more added value on top of copper.

Well, I think it would make more sense to better use what's available before building new power generators. Power use in Santiago is hugely inefficient, insulation and building standards have been talked to death in this forum. And you never know, your hydroelectric dam down there might suddenly develop a drain :shock:

I checked out the website for the SIC, https://www.cdec-sic.cl/index_en.php... actually very informative, and I know from a family friend who used to work for Endesa as a technical lead in maintenance for Endesa that they're pretty well run, and in fact I haven't experienced very many power cuts in my time in Chile. Considering that most of the power lines are above ground it's not bad.

The thing that gets me is that the mobile networks were out again.. that shouldn't happen. As I mentioned in another thread somewhere, the radio base stations have battery backups that will keep them going for several days, and the core network should have duplicate units and communications, as well as generator backup. In fact, in an emergency the network operator or their suppliers can override licensing limitations and allow use of the complete hardware capabilities, so the actual capacity in an emergency should be far in excess of the normal use. Someone has been "chamullando-ing" the consumers and possibly the regulator here, well designed mobile network shouldn't go down like that, and according to a Mexican friend who worked for Alcatel during a major earthquake up there, and saw "his" network survive in spite of the network operator's buildings collapsing... don't...
You are disturbing me. I am picking mushrooms.

For what it's worth, our VTR triple service was almost rock solid once the power came up, but we're a long way North of the earthquake. I think my parents said they weren't able to phone us first time from the UK, but I talked to them within a day or so using the VTR phone service (and before that by email). Of course the disadvantage is that when the power is out, the cable modem's battery dies after a few hours.
