There is a wave of development in Los Angeles' luxury markets that's been happening since 2014, and that wave is causing some crashes.One type of crash is the literal one: There are construction companies hauling massive amounts of equipment and supplies up and down small, winding streets, creating traffic woes and leading to fender benders.The homes in those areas are 384

This week's series of earthquakes served as a reminder that the United States' earthquake risk extends far beyond the Pacific Coast. On Tuesday, Puerto Rico was rocked by a 6.4 magnitude earthquake. The earthquake knocked out power to most of the island, killing at least one. Also in recent days, minor earthquakes were felt in Tennessee and Texas. While there have been dozens of earthquakes with a 4.5 magnitude or higher throughout the United States in recent years, the eastern United States see relatively fewer. Only four earthquakes of 4.5 magnitude or greater in the last four years have impacted the eastern United States. But the issue is not the quantity of earthquakes in the eastern United States, but the impact. The USGS puts out a hazard map that shows the earthquake risk nationwide. The map shows areas such as the Pacific Coast and parts of Alaska and Hawaii with a high risk of peak ground accelerations. It turns out that areas of Missouri, Tennessee, Kentucky, Arkansas, Illinois and South Carolina.USGS scientist David Schwartz agrees that the Pacific Northwest all the way to Charleston, S.C., practically every region of the United States, has a risk of feeling a devastating earthquake."The nature of the crust changes as you go from east to west. The Central and Eastern US, the crust is really old, it is older it is colder, it is denser, than the crust in the west which is younger,” Schwartz said. “It’s broken up by many faults and warmer. These different crusts transmit seismic waves differently.”And this difference in geology means that a strong earthquake in the Eastern United States could cause damage over an extensive area.Although the Eastern United States has not had many major earthquakes in the last century, two of the most powerful quakes in American history have happened east of the Rockies. The magnitude 5.8 earthquake that caused damage to the Washington Monument in 2011 is only a minor example of the kind of earthquakes the Eastern United States could see.In 1811 and 1812, a series of earthquakes struck the Mississippi River valley along the New Madrid fault. The strongest of the quakes was a possible magnitude 7.8. The quake was felt across much of the Eastern United States.In 1866, a magnitude 7.0 rattled Charleston, S.C.“A repeat of any of those earthquakes would be extremely damaging, because the housing stock in the Central and Eastern U.S. has not been designed for earthquakes,” Schwartz said.According to a survey funded by the U.S. Army, a magnitude 7.7 earthquake located along the New Madrid fault could cause 85,900 deaths and 8 billion in damage. By comparison, Hurricane Katrina caused roughly 1,500 deaths and 0 billion in damage.What to do during an earthquakeDROP to the ground (before the earthquake drops you!),Take COVER by getting under a sturdy desk or table, andHOLD ON to it until the shaking stops. 2906

Thick, black graffiti sprayed onto a Russian polar bear's coat poses an extra threat to an animal already in danger, experts say.Video shared on social media shows a lumbering polar bear whose back had been branded with "T-34," the name of an old Soviet Union tank.The video was posted to Facebook on December 1 by Sergey Kavry, a World Wildlife Fund employee who lives in the remote Russian region.In the comments, Kavry said he obtained the video via WhatsApp from indigenous minorities in Chukotka, in Russia's far east, though it is not clear from the video where it was filmed.Polar bears are having to 620

The Transportation Security Administration plans to send hundreds of officials to help with efforts to deal with migrant inflows on the southern border just as the busy summer travel season begins, according to an internal email obtained by CNN.The task of the TSA workers, which a source said will include air marshals, will be to assist temporarily with immigration duties. TSA acknowledged in an internal email the "immediate need" comes with the acceptance of "some risk" of depleted resources in aviation security.TSA plans for the deployments to involve up to 175 law enforcement officials and as many as "400 people from Security Ops," according to two sources and the email. At least initially, the efforts will not involve uniformed airport screeners, according to the email, which says that some parts of TSA would be asked to contribute "around 10%" of its workforce."There is now immediate need for more help from TSA at the SW border," a senior TSA official, Gary Renfrow, wrote in the email to agency regional management. "TSA has committed to support with 400 people from Security Ops" who will be deployed in waves "similar to support for past hurricanes.""We also understand that we are accepting some risk as we enter a very busy summer," Renfrow wrote, calling this effort an "additional challenge."The initial law enforcement teams will be drawn from six cities, according to a source familiar with the plans.The spokesman for the Department of Homeland Security referred questions to TSA, which did not comment.While airport checkpoint screening may be the most visible part of TSA, Juliette Kayyem, a former DHS official who is a CNN analyst, noted these deployments would draw employees from important behind-the-scenes security work. "That's sweeping airports, that is monitoring activity on the inside and outside of the security line, they're supporting local and state law enforcement," she said.The assignment comes as the number of illegal border crossings is spiking, with apprehensions at a 10-year high. Some 4,300 active duty and National Guard troops are currently assisting on the border, the acting defense secretary said recently, and Customs and Border Protection shifted 750 of its own officers to assignments with Border Patrol last month. Before her ouster as Homeland Security secretary last month, Kirstjen Nielsen 2370

The powerful tornadoes that plowed through Lee County in Alabama and killed at least 23 people left a path of destruction that looked "as if someone had taken a blade and just scraped the ground," the county sheriff said Monday.At daybreak, emergency crews and residents witnessed more of the aftermath of the twisters that Sheriff Jay Jones called "catastrophic," and the search was on for survivors and more victims.It appears that some people had only a five-minute warning Sunday afternoon before tornadoes ripped through the region.A tornado watch was issued for the area around noon. The first tornado warning for Lee County was issued at 2:58 p.m. ET, and the first reports of damage came just five minutes later, CNN Meteorologist Gene Norman said, according to National Weather Service data.It appeared that two tornadoes hit Lee County back-to-back within the span of an hour, Norman said.A warning for a second tornado was issued at 3:38 p.m. ET, with the first reports of damage coming 13 minutes later.At least a dozen tornadoes touched down in Alabama and Georgia on Sunday afternoon, according to the NWS.The National Weather Service recorded EF-3 damage in southern Lee County. That classification means the damage was severe, with winds of 136 to 165 miles per hour.How the destruction unfoldedTornado watch for Lee County issued around 12 p.m. ETTornado warning 2:58 p.m. ETFirst reports of damage 3:03 p.m. ETFurther damage reports 3:30 p.m. ETSecond tornado warning 3:38 p.m ETFirst reports of damage 3:51 p.m. ETMore damage reported 4 p.m. ETAlabama's deadliest since 2011The 23 deaths reported on Sunday marked the deadliest day for tornadoes in Alabama since the Tuscaloosa-Birmingham tornado that killed more than 200 people in 2011.The victims, including children, died in Lee County, Jones said. At least 12 of those deaths occurred in an area about 5 to 6 miles south of the city of Opelika, he said.Jones told 1950
