WOODBURNING STOVES

Since heavy objects such as stoves are actually more likely to move during strong ground shaking than lighter objects, they pose more hazards. Some fire codes dictate that stoves be unsupported on all four sides. As a result, they are more vulnerable to sliding or overturning during an earthquake. If the stove were to tip and/or separate from the stove pipe, cinders or sparks might easily cause a fire in the home. To reduce fire potential following a shaker, anchor the stove to the floor and make sure stove-pipe sections are secured. It's important that the seismic anchors or braces do not conduct heat from the stove. Although there are many types of stoves in use, the following recommendations can be used for most installations:

Stoves sitting on a brick hearth can be anchored using bricks and mortar. Units resting on a cement slab on grade can be anchored directly to the concrete. Stovepipes should be anchored to the flue exit, and each of the stove-pipe segments should be secured together. Mobile home approved units come with predrilled holes in the pedestals or legs and can be safely anchored to the underlying floor framing.



WATER HEATERS

If a water heater falls during an earthquake, it could break a gas line and start a fire. To minimize this risk, add flexible connections to both the gas and water lines. To keep the water heater from toppling over, wrap it with two bands of 1-1/2" x 16-gauge perforated steel commonly known as plumberÕs tape. Connect the bands to nearby wall studs with metal struts cut to length from 1 /2" diameter wall EMT conduit. Each end of the strut is then flattened, drilled and bent at an angle to fit the wall.

For this project you will need:
1-1/2" x 16-gauge predrilled strap
1/2" EMT conduit tubing
4 - 5/16" x 3" lag screws with 1 washer each
4 - 5/16" x 3/4" long hex head machine bolts with 1 nut and washers each
2 - 5/16" x 1-1/4" hex head machines bolts with 1 nut and washers each

Tools needed to complete the work are tape measure, hammer, hacksaw, wrench set, vise or clamp, power drill, drill bits, center punch and a pencil.






AWESOME AURORAS

Shock waves generated by last week's CMEs (coronal mass ejections) from a giant sunspot 9393) impacted Earth March 31st . This shock wave front was dense and heavily magnetized - two vital components of powerful geomagnetic disturbances. Spectacular Northern Lights were observed as far south as Mexico in the Northern Hemisphere and in New Zealand.

MORE ON THE WAY

If you missed this latest chance of seeing auroras or they were obscured by cloud cover like Stan and I experienced, you may have another shot this weekend. Old Sol has been a busy boy shooting off an X5-class flare right on the heels of an M5 flare Thursday. This newest CME, too, appears to be somewhat Earth-directed. People living above 55o (this runs generally through the midpoint north and south of Canadian provinces: British Columbia, Alberta, Saskatchewan and Manitoba) should have the best viewing opportunities.

SOHO captured another tremendous flare Friday shooting from Region 9415.

Keep looking up! You're bound to see something exciting!

Seismo
: (grunt... puff...) "Well, I'm using our new stretchable leashes to anchor my food bowl in case of an earthquake..."

Taco
: "But... Seisie, to yourself?...!!!"
