By downloading this file and opening it in Google Earth, users are able to browse hillshades with two illumination angles (315 and 45 degrees) for faults in the northern San Andreas fault system. The extent of the LiDAR data is shown by the cyan colored outlines. The hillshades will load once the user has zoomed into an area of interest.
Earthquakes happen daily around the world, with hundreds of millions of people living in earthquake prone regions. An early warning can help people prepare for shaking, but the public infrastructure to detect and alert everyone for an earthquake is costly to build and deploy. We saw an opportunity to use Android to provide people with timely, helpful earthquake information when they use Google search, and a few seconds warning to get themselves and their loved ones to safety if needed.
In California, Washington, and Oregon, we partner with the ShakeAlert team to distribute alerts provided by their system. ShakeAlert uses a network of 1675 seismic sensors to detect earthquake shaking, and analyzes that data to determine the location and size of the earthquake. The ShakeAlert system then sends a signal to Android Earthquake Alerts System, which then sends an earthquake alert directly to Android users.
Tapping on either of the alerts will present Earthquake safety information, which consists of simple steps that you can take to keep yourself safer after an earthquake. It also provides a detailed map of an early estimate of the earthquake location and magnitude.
The Awesome Android was based on the work of the Fantastic Four's leader Mr. Fantastic and built by the Mad Thinker when he briefly took over the Fantastic Four's headquarters within the Baxter Building. When the Fantastic Four fought through their own security systems, the Awesome Android was used to fight them as well but was easily incapacitated by the heroes when Richards disabled the android through a nerve under its arm. The Mad Thinker was defeated; shortly thereafter the Awesome Android was defeated.[4]
The Awesome Android was used during a number of the Mad Thinker's early plots, such as when he teamed up with the Puppet Master and pitted the mutant X-Men against the Fantastic Four. When the heroes united to battle their mutual foes the Awesome Android was used to keep them at bay while the Thinker and Puppet Master fled.[5] The Thinker and the Awesome Android were next manipulated by Dr. Doom to attack the wedding of Mr. Fantastic and the Invisible Girl. There they clashed with the Fantastic Four and other heroes that were attending the wedding until all the villains that were summoned were banished with the Watcher's Time Displacer device.[6][7] The Awesome Android was next used when the Thinker attacked Manhattan but both were once again defeated by the Fantastic Four with the assistance of the X-Man known as Marvel Girl.[8] The Awesome Android was next deployed when the Mad Thinker was hired to capture industrialist Tony Stark, which led to a battle against Stark's alter-ego Iron Man. Once again the Thinker and his android were defeated.[9]
The Mad Thinker then ceased using the Awesome Android for a time and apparently at some point the Awesome Android was captured and incarcerated in the Vault prison. It attempted to escape but was recovered by the Avenger known as Moondragon.[10] The Mad Thinker eventually recovered the Awesome Android when he joined the Intelligencia. He then used his Awesome Android to help infiltrate the Eternals city of Olympia to ransack its collection of Alexandrian era texts as well as a cosmic powered robot designed to resemble the Hulk.[11] Sometime after this the Mad Thinker learned of the existence of the alien Spaceknight known as Rom. Believing Rom to be an android he sent his own Awesome Android to battle Rom. The Awesome Android was seriously injured by Rom's weapons and exerting a small sliver of free will fled the scene with his master.[12] Furious the Mad Thinker ordered the Awesome Android to wait for his next set of orders in an abandoned barn in Mayfield, Ohio.[13]
The Awesome Android was discovered by a young boy who wrote to Marvel Comics asking for the help of Captain America. Incidentally enough at the time, Cap was working as an artist for Marvel at the time in his secret identity of Steve Rogers and read the letter. Going to Ohio to investigate, Cap was attacked by the Android whenever he got within close proximity of it. Realizing that it would be of no harm to anyone so long as nobody got close to it, he decided to leave the android alone.[13]
Later when the Super-Adaptoid, posing as the Fixer was being hunted by the Avengers, their battle took them to the Ohio barn where the Awesome Android was waiting. The Avengers then had to defend themselves from the Android, allowing the "Fixer" to escape capture[14] the Awesome Android was then detained at the Avengers Hydrobase headquarters.[15] The Super-Adaptoid then began gathering other robots forming a group called Heavy Metal.[16] They then attacked Hydrobase so that the Super-Adaptoid could get information on the Cosmic Cube. During the attack the Adaptoid reactivated the Awesome Android who joined Heavy Metal's battle against the Avengers. During the fight the Awesome Android was incapacitated when the Sub-Mariner ripped off the android's head. During the attack the Super-Adaptoid managed to recover the Cosmic Cube and replicate its power.[17] However the Avengers eventually defeated the Super-Adaptoid.[18] The Awesome Android's remains were turned over to the United States government and stored at Hydrobase along with the remains of the other robots.[19] During the Acts of Vengeance conspiracy a consortium of super-villains sank the Avenger's Hydrobase headquarters.[20] In the aftermath, the captured robots were all recovered by the villains except for the Awesome Android who was left behind to attack anyone who went to recover anything from the ruins. When the Avengers Quasar and Stingray went to recover the computers from Hydrobase they had to fight off the Awesome Android.[21] Getting to the surface the Awesome Android attacked the Avengers but was ultimately stopped by Firebird and Captain Marvel.[22] The Awesome Android was later pulled forward in time to assist Aron the Rogue Watcher against the Fantastic Four and Fantastic Force. When Aron was defeated, all his thralls were returned to their proper time and place with no memory of what happened.[23]
The Mad Thinker then made improvements to the Awesome Android, making it capable of copying any traits, not just superhuman powers. The Thinker then sent his android to attack the Asgardian thunder god Thor. During the fight, the Awesome Android copied Thor's nobility sparking an independent intelligence within the Awesome Android. It then helped Thor apprehend the Mad Thinker and sought out a lawyer at the law offices of Goodman, Lieber, Kurtzberg & Holliway. Lawyer Holden Holliway took the Awesome Android's case and proved to the court that the android was a victim of the Mad Thinker's crimes, clearing the android's name. Since the Awesome Android did not have any money, he agreed to work for the firm.[1]

The Northern California earthquake of April 18, 1906, commonly referred to as the Great San Francisco Earthquake of 1906", is the most damaging earthquake in US history. San Francisco and surrounding cities were violently shaken by seismic waves produced by the magnitude 7.9 earthquake. The remarkable post-earthquake construction and renaissance of the Bay Area are important events in the history of the region. The 1906 earthquake also revealed the existence and significance of the San Andreas fault to earth scientists, who then gave birth to the science of earthquakes. This virtual tour utilizes the geographic interactive software Google Earth to explain the scientific, engineering, and human dimensions of this earthquake, so as to help you visualize and understand the causes and effects of this and future earthquakes.
The full significance of the horizontal slip on the San Andreas fault in 1906 would not be appreciated until the advent of plate tectonics more than half a century later. It is now known that the San Andreas fault accommodates most of the relative plate motion between the North American plate to the east and the Pacific plate to the west, about 1.5 inches/yr (4 cm/yr). This relative plate motion and the strain it imposes on the San Andreas fault was the cause of the 1906 earthquake and is the cause of earthquakes yet to come.
The 1906 earthquake initiated beneath the ocean just west of San Francisco and simultaneously ruptured the San Andreas fault to the northwest and southeast. The rupture has been traced 202 miles (325 km) to the northwest to near Cape Mendocino and 93 miles (241 km) to the southeast to near San Juan Bautista. Strong shaking was felt in the Bay Area for 45-60 seconds.
The large number of photographs taken shortly after the 1906 earthquake are utilized by scientists to document surface rupture of the San Andreas fault and by engineers to document the extent and nature of damage to the built environment, including the liquefaction that occurred on the filled margins of San Francisco Bay.
In 2006, the San Francisco Bay Area is a vastly different place from what it was 100 years ago. With a population of more than 7 million people dependent on a complex and vulnerable infrastructure the Bay Area is vulnerable to the effects of future earthquakes in the region. See the maps showing the densely urbanized parts of the Bay Area and maps of earthquake probabilities and liquefaction susceptibility.
