U.S. Geological Survey Earthquake Hazards Program
The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977. We monitor and report earthquakes, assess earthquake impacts and hazards, and research the causes and effects of earthquake. Significant Earthquakes Past 30 Days

Why Earthquake-Resistant Cell Phone Towers Are Worth the Money - Pacific Standard Last week, Los Angeles became the first American city to require that new cell phone towers be built to withstand an earthquake. Previously, cell towers only needed to be able to resist falling (and killing people) during a quake, the Los Angeles Times reports. This new law is a reflection of changing times. The last major California earthquake was in the Northridge neighborhood of Los Angeles, in 1994.

Russian meteor blast injures at least 1,000 people, authorities say Described as once-in-100-years event, the meteor released a 300-kiloton blastlt had been moving faster than normal because of its close proximity to the EarthDeep Space Industries said countries should be proactive in establishing "a sentry line"A bright white flash appeared in the sky for a few seconds, followed by a heavy bang Did you see the meteor? Share your images with CNN iReport. Moscow (CNN) -- A meteor streaked through the skies above Russia's Urals region Friday morning before exploding with a flash and boom that shattered glass in buildings and left about 1,000 people hurt, authorities said. Described by NASA as a "tiny asteroid," the meteor's explosion created a blast in central Russia equivalent to 300,000 tons of TNT, the space agency's officials said Friday, adding that the incident was a once-in-100-years event. The injured included more than 200 children. - Live Flight Tracker! In order to save data consumption Flightradar24 web page times out after 30 minutes.

Stark Photos Show Nepal’s Heritage Sites Before and After the Quake Historical Monuments after the earthquake at Kathmandu Durbar Square. Image by Ajaya Manandhar. Copyright Demotix (25/4/2015) The earthquake that shook Nepal on April 25 has claimed more than 7,000 lives and injured twice as many people. Around 8 million people have been affected with at least 2 million displaced. Besides the human casualties and property damage in the billions, the earthquake devastated world-renowned monuments—many of them World Heritage Sites.

Gheorghe Marmureanu: “Something is wrong! There are too many strong earthquakes” The Earth is shaking! Scientists find no explanation to the 39 earthquakes that rocked the planet in just two days. “Something is wrong! There are too many strong earthquakes” believes Romania’s top seismologist, Gheorghe Marmureanu, who finds the latest Indonesian quake very unusual.The series of tremors debuted with the two big quakes (8.6 and 8.2 on the Richter scale) that rocked Indonesia these days. Just hours later, three more earthquakes panicked Mexico (7, 6.9 and 6.2 on the Richter scale). 2011 Tōhoku earthquake and tsunami The 2011 earthquake off the Pacific coast of Tōhoku (東北地方太平洋沖地震, Tōhoku-chihō Taiheiyō Oki Jishin) was a magnitude 9.0–9.1 (Mw) undersea megathrust earthquake off the coast of Japan that occurred at 14:46 JST (05:46 UTC) on Friday 11 March 2011,[5][11][12] with the epicentre approximately 70 kilometres (43 mi) east of the Oshika Peninsula of Tōhoku and the hypocenter at an underwater depth of approximately 29 km (18 mi).[5][13] The earthquake is often referred to in Japan as the Great East Japan Earthquake (東日本大震災, Higashi nihon daishinsai)[14][15][fn 1] and is also known as the 2011 Tōhoku earthquake,[30] the Great Sendai Earthquake,[31] the Great Tōhoku Earthquake,[31] and the 3.11 earthquake. Earthquake The main earthquake was preceded by a number of large foreshocks, with hundreds of aftershocks reported.

The Powers-That-Be seem to be making a continuous effort to drive a stake right into America's heart(land). Natural disasters are on the rise, and an increasing amount of evidence is leading to the conclusion that these natural disasters might not be completely natural. Louisiana Sink Hole - Will This Trigger the Big One? As you peruse the points below and the accompanying illustrations, you'll see a very clear, seriously dangerous weak spot. If someone wanted to deal a disastrous blow to this nation, where would you trigger a "natural disaster" if you could? The recent developments with the growing Louisiana sinkhole caving into a potentially massively explosive gas repository also used for nuclear waste storage is something to keep a close eye on and take very seriously.

Google Map Maker Google Map Maker officially closed on March 31, 2017, and many of its features are being integrated into Google Maps. Since 2008, the Google Map Maker community has edited and moderated millions of features to improve the Google Maps experience. To make it easier for all Google Maps users to contribute changes to the map, we’ve started to graduate functionality from Map Maker to Google Maps on both desktop and mobile. Key editing features currently available in Google Maps include:

Why women are more at risk than men in earthquake-ravaged Nepal Natural disasters are thought to be indiscriminate killers—but is that strictly true? It turns out disasters affect women much more than men. A 2007 study by researchers at the London School of Economics and the University of Essex found that between 1981 and 2002, natural disasters in 141 countries killed significantly more women than men, and that the worse the disaster, the bigger the gender disparity. The latest figures from Nepal show that among the 1.3 million affected by the earthquake, about 53% are female—a small but not yet statistically significant bias. That might soon change. According to the Women Resilience Index, a metric developed to assess a country’s capacity to reduce risk in disaster and recovery for women, Nepal scores a paltry 45.2 out of 100.

Multiple Degrees of Freedom Application This educational application allows the user to explore the effects of different building parameters on the time-varying response of a building under earthquake, wind, or other transient loads. The building is represented by a shear building model: an idealization of a structure in which the mass is lumped at the floor levels and the beams are assumed infinitely stiff in flexure and axially inextensible, and the columns are axially inextensible. The user inputs the floor weights and story properties (stiffness, yield strength, hardening ratio) of the stories, and a damping ratio for the structure. The user selects from a series of included ground motion acceleration records, or user provided motions. The user can quickly explore the effect of changing weight, height, and stiffness on the tine history response. In addition nonlinear effects due to P-Delta and soft story mechanisms can be studied.
