Satellite image (SAR, Sentinel-1) of the Rishiganga Hydroelectric Project (RGHEP) - located at 30.483056, 79.699722 per project documentation. Imaging taken 2021-02-03 12:47:48 UTC #Uttarakhand #Disaster
Image on 2021-02-06 00:35:34 UTC (partial), unsure where the dam is exactly. Sentinel-1 synthetic aperture radar. #Uttarakhand #Disaster
This is likely pre-flood....
Google Earth imaging of that location where the dam is located, very steep walls.. I believe (given news reports) the valley on the right is the one with the glacier above and dam somewhere here in the bottom. 30.483056, 79.699722
Sentinel-2 satellite imaging of the dam location (via @sentinel_hub) taken pre-break 2021-02-05
05:30:31 UTC #Uttarkhand #disaster
3D view of the same. Can't tell exactly which parts are the dam or not. Sentinel-2 2021-02-05 05:30:31 UTC (pre-break). Next visible pass should help w/damage viewing.
This looks like a dam.... to the west, at 30.490, 79.645 #Uttarakhand

There are lots of things that will pay off in #California as #preparation for upcoming heatwaves and wildfires, *now* (when it's cool, and when it's not during fire season) is the time to get them done.
1. Improve the insulation in your house. Most older California homes are under-insulated. Add a layer of insulation to your attic. Tax deductible, usually, pays for itself. Can dramatically lower your temps. during heatwaves.
2. Make adjustments to make your landscaping more fire resistant. Lots of resources from CALFIRE here: readyforwildfire.org/prepare-for-wi…

More on the guy who got lost trying a shortcut on his GPS using Henness Pass Road *during an atmospheric river*.
This is that road, when the snow starts melting... alltrails.com/trail/us/nevad… Image

Personal #preparedness lessons from the #wind #storm: 1. Upgraded UPS units worked great, much better than UPS-destroying planned blackout. APC 19 inch rackmount units, ex-corporate units. 1/x
2. SMA solar inverter's SPS (Secure Power Supply) worked very well for recharging 2 of the 3 identical model UPS units. Third triggered GFCI outlet I have on the SPS every time. 2/
3. UPS unit powering my switch, Wi-Fi router lasted 5 hours before I had to charge it with the solar. Another UPS--with new batteries from Amazon--powering just few other components lasted 3.5 hours, those batteries are not very good. UPS on desktop only lasted 2 hours. 3/

High tech heat pump/hybrid water heater installed. Waiting for hot water. Acting as a serious AC unit for the garage, so far. Replaced the 20 year old gas water heater. Cross fingers.
Some asked about the noise. It's definitely louder than a gas driven water heater; not as noisy as an A/C unit, but it's fairly loud in the garage as it warms up. You can hear it in the room directly adjacent to the unit, but not in the rest of the house.
It's taken awhile for it to bring the tank up closer to temp, now getting warm water out of the tap. Still cranking away, the garage (65F) is now significantly colder than outside (78F). Surfaces near the air outlet are reading ~50F. Working well as an A/C unit!

This #pandemic preparedness stuff is from FEMA/CERT, disappeared from the web earlier this month but may be useful. Thread below.
Basics on #pandemics (note: this particular one does *not* appear to affect infants as much, thankfullly).
CERT/FEMA's materials suggest two weeks of food/water. I know there's a lot of debate about water; this is what CERT/FEMA has in the material on pandemics, (same recommendations as DHS/etc.). (My note: Wuhan is on week 7 or 8 of lockdown)

Homeland Security has a great document "Information for First Responders on Maintaining Operational Capabilities during a Pandemic" - Here's the EMS section... firstwatch.net/wp-content/upl…
Some generally applicable tips for anyone out of this: "Use wipes—not sprays—to decontaminate equipment and exposed surfaces in vehicles post-response. Wipes are recommended to avoid re-aerosolizing the germs or bacteria on contact."
"Do not recycle or reuse anything that could be contaminated."
