Is the US West Coast next for a major quake?
Michael Martin:
Noticed a "swarm of earthquakes" in the Puerto Rico region when I checked the world earthquake list this morning:

On the region map for the Puerto Rico Region quakes, there are 54 quakes listed on the map (I counted 39 from the list above so the other occurred earlier than yesterday's swarm):

And now, here's a brand new fish kill up in Ventura: http://www.sott.net/articles/show/227440-California-Hundreds-of-dead-fish-found-in-Ventura-Harbor, coupled with an earthquake swarm in Nevada: http://www.sott.net/articles/show/227357-Nevada-US-Swarm-of-Quakes-have-Experts-Concerned. And, of course, FEMA is conducting an earthquake drill in Oklahoma on the 28th: http://www.sott.net/articles/show/227365-Preparing-for-the-Big-One-In-Central-US-Earthquake-Drill-April-28.
So, let's wait and see as to where the next huge earthquake happens next.

Just yesterday we had a 3.4 in the San Francisco Bay Area: http://earthquake.usgs.gov/earthquakes/recenteqsww/Quakes/nc71560691.php
I thought it was curious when looking at the epicenter of the quake was its proximity to the location of the gas pipeline explosion in San Bruno which is about 2 miles away.
One of the concerns that I have is that the Hetch Hetchy pipeline is quite old and a severe earthquake would have serious consequences for the fresh water supply in the Bay Area. The storage lakes for San Francisco fresh water are located on San Adreas.
Also infrastructure would be badly damaged, e.g. part of Hwy 280 near Woodside is right on top the San Andreas fault line system.
I feel really bad for the people in Big Sur that were cut off by the collapse of Highway 1. First the terrible wildfire a couple of years ago and now this.

Good article for some signs, that might be observed prior to a major event. It is four pages long, so it is better read from the link, as it has certain illustration's connected to the article.

Earthquake Alarm Impending earthquakes have been sending us warning signals--and people are starting to listen By TOM BLEIER, FRIEDEMANN FREUND / DECEMBER 2005
http://spectrum.ieee.org/computing/hardware/earthquake-alarm
--- Quote ---Deep under Pakistan-administered Kashmir, rocks broke, faults slipped, and the earth shook with such violence on 8 October that more than 70 000 people died and more than 3 million were left homeless [see photo, " Devastated"]. But what happened in the weeks and days and hours leading up to that horrible event? Were there any signs that such devastation was coming? We think there were, but owing to a satellite malfunction we can't say for sure.
How many lives could have been saved in that one event alone if we'd known of the earthquake 10 minutes in advance? An hour? A day?
Currently, predictions are vague at best. By studying historical earthquake records, monitoring the motion of the earth's crust by satellite, and measuring with strain monitors below the earth's surface, researchers can project a high probability of an earthquake in a certain area within about 30 years. But short-term earthquake forecasting just hasn't worked.
Accurate short-term forecasts would save lives and enable businesses to recover sooner. With just a 10-minute warning, trains could move out of tunnels, and people could move to safer parts of buildings or flee unsafe buildings. With an hour's warning, people could shut off the water and gas lines coming into their homes and move to safety. In industry, workers could shut down dangerous processes and back up critical data; those in potentially dangerous positions, such as refinery employees and high-rise construction workers, could evacuate. Local government officials could alert emergency-response personnel and move critical equipment and vehicles outdoors. With a day's warning, people could collect their families and congregate in a safe location, bringing food, water, and fuel with them. Local and state governments could place emergency teams and equipment strategically and evacuate bridges and tunnels.
It seems that earthquakes should be predictable. After all, we can predict hurricanes and floods using detailed satellite imagery and sophisticated computer models. Using advanced Doppler radar, we can even tell minutes ahead of time that a tornado will form.

Earths Many Voices a Unified Theory for Pre-Earthquake Signals
http://www.youtube.com/watch?v=Y2ZwR9Dxbmo
Abstract:
--- Quote ---In this talk, I will discuss the solid-state physics of rocks and earthquake precursors. Earthquake precursor phenomena have been known for some time. They are caused by stresses that build up in crustal rocks. As we have found in the laboratory, these stresses more precisely, differential stresses and strains activate mobile positive charge carriers (defect electrons in the oxygen anion sublattice sublattice: O in a matrix of O2). These positive holes (or pholes for short) flow from the generation region into the surrounding rock. They effectively turn a rock into a giant battery. Under specific conditions, which cause the battery circuit to close, large phole currents can flow. Such currents lead to a variety of phenomena: (i) magnetic field variations and low to ultra-low frequency EM emissions, (ii) ionospheric perturbations over the epicentral region, (iii) air ionization at the ground-air interface and corona discharges with light and radio noise, and (iv) the emission of narrow-band infrared (IR) photons around 10 µm. These excess IR photons are the cause of the so-called thermal IR (TIR) anomaly. Often appearing days before major earth¬quakes, TIR anomalies have been seen from space by NASAs MODIS on TERRA and AQUA, by NOAAs AVHRR and GEOS, by Europes METEOSAT satellites. These various pre-earthquake signals can be used to design an earthquake early warning monitoring system, combining space assets and ground networks.
