Exactly. The lake tilting is a good indicator, but the center of the lift may be away from the lake itself, and the lake could be on the side of the uplift. Also, look at the calderas on the last 3 major eruptions in Yellowstone... they overlap, but rarely use the same border. IMO, I think this is swarm due to magmatic movement, and will taper off in a bit after becoming more shallow. At the same time, I think that several geysers and hot springs will change their schedule, temp, or chemical composition in the coming weeks... and some new ones may form, or old ones may grow dormant. It will be interesting to watch, though.
As for the pair of shallow quakes, they are of large enough magnitude that I seriously doubt they are reflections of anything. After all, to be reflections, they have to be reflecting *something*. The timing is off, as is the magnitude. I think the lower quakes may be unsettling rocks and such further up, which is *not* a good trend to start. They may also be hydrothermal in origin, rather than magmatic.
(until we see quakes consistently hit in the 5-6km range, I wouldn'be too concerned)

All of Orange County has been hit hard with rain this week, but some areas could feel the impact of it more than others.
It’s no secret that hilly Laguna Beach is subject to landslides, but do you know how to recognize the signs of an oncoming landslide before it happens?
Here are FEMA’s tips on how to anticipate an oncoming landslide and what to do after one happens: lblandslide
Signs of an oncoming landslide:
* Changes occur in your landscape such as patterns of storm-water drainage on slopes (especially the places where runoff water converges) land movement, small slides, flows, or progressively leaning trees.
* Doors or windows stick or jam for the first time.
* New cracks appear in plaster, tile, brick, or foundations.
* Outside walls, walks, or stairs begin pulling away from the building.
* Slowly developing, widening cracks appear on the ground or on paved areas such as streets or driveways.
* Underground utility lines break.
* Bulging ground appears at the base of a slope.
* Water breaks through the ground surface in new locations.
* Fences, retaining walls, utility poles, or trees tilt or move.
* A faint rumbling sound that increases in volume is noticeable as the landslide nears.
* The ground slopes downward in one direction and may begin shifting in that direction under your feet.
* Unusual sounds, such as trees cracking or boulders knocking together, might indicate moving debris.
* Collapsed pavement, mud, fallen rocks, and other indications of possible debris flow can be seen when driving (embankments along roadsides are particularly susceptible to landslides).
How to recover from a landslide:
* Stay away from the slide area. There may be danger of additional slides.
* Check for injured and trapped persons near the slide, without entering the direct slide area. Direct rescuers to their locations.
* Watch for associated dangers such as broken electrical, water, gas, and sewage lines and damaged roadways and railways.
* Replant damaged ground as soon as possible since erosion caused by loss of ground cover can lead to flash flooding and additional landslides in the near future.
* Seek advice from a geotechnical expert for evaluating landslide hazards or designing corrective techniques to reduce landslide risk.
I nominate the Quote of the day award for Presslord
It's not a expotential uptake of earthquakes. If you look back into history you will see times were lot's of earth quakes happened and times of no activity. Were in a time of more activity. Plates and faults are always moving and causing stress. History tells us that a really bad quake happened in Haiti 200 years ago, but it was so long ago no body is alive that went through it, so it becomes a story or historical event.
THAT is what this relief effort is about. That is the image that the world should see about this whole effort. It isn't about crumbled buildings, or totaled palaces. It is about the people. The children. The people whom have done no wrong, yet mother nature has chosen to inflict this terror upon their lives. Those are the people we, as a world community, are working to help. Those are the people that Portlight is working to help.
I can't sleep.
Do you have a fan to use?

That is exactly right.
There are several people that claim tornados, hurricanes and earthquakes are increasing in frequency. In reality, there is just mroe technology to detect all of these natural disasters.
Maybe you want to read the article again than.
Including both studies. The discussion ends here for me with you. Have a nice day.
Our highest nado counts come in what ENSO conditions? La Nina. Exactly the same polarity of ENSO most any AGW fan claims there will be fewer of (and more El Ninos) just as there was in the last positive phase of the PDO.
And you would like to say more nadoes.
So you want to claim more nadoes and more El Ninos...2 things that actually are in direct opposition to each other.
Additionally, yes, the observational, survey, and reporting systems have matured extensively, even in just the last 20 years.
I'm thankful that is far enough off the coast to not have a huge impact. If that was a few hundred miles closer, it would be a particularly nasty nor'easter.
I read it. Says, "It is a guess", and those with the most to lose (monetarily), the reinsurance industry, says there is no such thing as earthquake weather.
"The consensus in the scientific community: the swarm of earthquakes is caused by tectonic shifts, not anything to do with the Yellowstone caldera. These same shifts are causing more severe earthquakes in areas like Haiti and Oklahoma. Other monitoring stations indicate no change at all in activity with the caldera and the Yellowstone supervolcano."
