Earthquake and Possible tsunami (seiche) 30 ft high.
What to Do:
In the event of an earthquake move away from windows and doors that face the lake. Take cover under a heavy desk or table. Doorways are not recommended now.
Wait a couple of minutes if the tsunami is initially moving toward the cabin it will hit in a minute or 2.

If there's a tsunami (assume there is with a big earthquake) and it's initially moving toward Nevada as expected, you've got 6 minutes to get up to Sacramento St. or higher.
Guests, Children and Old Folks should evacuate immediately.

20-30 year old family members and crazy old men, if they feel brave might try the following. Don't be stupid. Save yourself forget the house.
Summer or Winter:
Get the hard hat out of the front closet Turn off the gas - There is a wrench on the post by the gas meter.
Turn off the water - Turn the middle valve by the hot water heater 1/4 turn to the right
Summer: (You won't have time to get thru the snow to higher ground in the winter and the tsunami will probably knock out electricity anyway.)
Turn off the electricity- Main circuit breaker on the back porch.

Background:
Earthquakes strike every 3,000 to 4,000 years on the fault under the west side of the Lake. See Earthquake-Tusnami. The West Tahoe Fault last moved 4,500 years ago Gene Ichinose of the UNR seismological laboratory studied the faults underneath the lake and they estimated that the probability of such an event (Magnitude 7 - 7.3) would be around 2-4% in the next 50 years.
In the event of an earthquake move away from windows and doors that face the lake.

The east side of the fault would probably drop so the wave would head to the east shore, bounce off and head back, reaching the west shore in about 6 minutes after the quake hit, it would take another 3 or 4 minutes to reach maximun height.

The maximum elevation of the lake is 6,230 feet so the wave would reach 6,260 ft.

The deck of the cabin is 6,239 ft, so the wave would be near the top of the cabin.

The elevation of Sacramento Street is about 6,260 ft , so it would be easy to walk 300 ft. thru the neighbors yard to Sacramento St or less than 4 minutes at a brisk walking pace (2.5 MPH) to go 880 ft (1/6 mi) down to the ski area up to the first lift to be safe and get a better view.
