Earthquakes, volcanos and food security

Oh bother, we just had another earthquake. This one was 2.7, but we were right on top of it. The epicenter was only a couple of miles away, so we definitely heard and felt it. A quick jolt, lots of rattling, no damage. We always wonder if that was all there was, or was that just a precursor to the “big one.”

 That little red square off by itself on the coast of southern California is the quake that just happened.

 We can go years without feeling an earthquake, but the earth seems very active these days with big quakes in Chile, Baja, and China. Earthquake activity in Baja is continuing after the Easter quake (see map above), but we don’t feel them. Living in earthquake (or hurricane, or tornado, etc.) country means that we should always be prepared to get by for a week or two on our own before help arrives. We keep a water supply plus dried and canned food for emergencies.

And how about that volcano in Iceland causing the worst disruption of air travel in history? I’m supposed to fly to Europe with my camera group soon, so I’m following that news anxiously. Hard to say whether we’ll actually be going or not. (Vic isn’t going because his class schedule conflicted with the dates of our trip. )

I suppose a silver lining to this ash cloud is that it will cool off the planet a bit and help offset global warming. This will buy us a couple more years time. But if we don’t reduce carbon dioxide and methane emissions, the cooling will be temporary.

The volcanic dust will block some of the sunlight that would normally reach Europe and possibly Russia this spring. If the eruption continues, we may experience less sunlight here in the U.S. as well. I wonder if crops will be affected. If they are, then the cost of food will go up.

Life is uncertain. That is just one more reason why I garden and keep hens. I want at least the illusion of food security. I try to grow a wide variety of things that are planted at different times to hedge my bets. If one crop fails, perhaps a different variety or the same one planted at a different time will produce.

Wax beans, patty pan squash, eggplant and chard promise a good harvest.

The tiny bit of fruit and veggies that I’m able to grow won’t keep us from starving to death if a global crisis occurs, but it brings me comfort to know that I have at least some food in my yard. Our garden is a form of insurance, a hedge against natural (or unnatural) disasters and the vagaries of weather and climate.

I'm a retired medical researcher, retired professional writer/photographer, avid gardener, and active environmentalist living in southern California. I wrote a weekly newspaper column on environmental topics in the Huntington Beach Independent for many years. I also supervised environmental restoration projects and taught at the Orange County Conservation Corps before retiring in the summer of 2016. This blog chronicles my efforts to live a green life growing as much food as possible for my husband and myself on a 4,500 sq ft yard that is covered mainly by house, garage, driveway, and sidewalks. I am also dedicated to combatting global climate change.

    We also felt it, as we are less than a block from the Santa Ana river, about a mile and a half inland. The jolt was just as you described. I, too, wonder if that cloud of ash will affect crops. I did hear some expert say, the other day, that the ash is not as high as the Krakatoa explosion was, and won’t drift as far. Cold comfort for Europe!


    • Cold comfort indeed, Kathy. In the long run, volcanic ash improves soil, but in the short run it blocks sunlight. Every single gardening year seems different from previous ones, a fun challenge.

    Fascinating to learn that the atmosphere filling with volcanic ash will help cool the earth and improve the soil – that’s a good thing! My (Japanese) husband just thought the volcanic eruption was Mother Nature farting at Europe…..

    Hey, don’t those things belch out a lot of sulfur and methane gas?? The ones in Japan sure do!
