There is a hotspot track cross-cutting the New Madrid Fault Lines!

And it may explain the upstick in recent intraplate earthquakes across the eastern United States!

There is a hotspot track cross-cutting the New Madrid Seismic Zone. The rectangular boxes show the locations of the seismic anomalies detected by USArray. The blue line shows the track of the hot spot. Black triangles are where diamond-bearing rocks from deep in the mantle have been found. Black and red lines are the boundary of the Mississippi Embayment and the New Madrid rift complex, respectively.  The inset globe shows where the hotspot is today and the ball shows the epicenter of the 2011 Virginia earthquake.

At present, most hotspot tracks are observed on oceanic or thin continental lithosphere.

For old, thick continental lithosphere, such as the eastern United States, hotspot tracks are mainly inferred from sporadic diamondiferous kimberlites putatively sourced from the deep mantle.

As shown in the above figure, scientists have discovered an unexpected linear seismic anomaly in the lower lithosphere.

The unexpected scar in the lower part of the crus has both a reduced P-wave velocity and high attenuation and thus has been interpreted as a hotspot track.

The anomaly extends eastwards, from Missouri to Virginia, cross-cutting the New Madrid rift system, and then bends northwards across a 75-million-year-old diamond-bearing formation in Kentucky.

There is no sign of the hotspot track on the surface.

The New Madrid rift system is responsible for some of the most powerful earthquakes in North American history and this newly discovered hotspot track could explain the late Mesozoic reactivation of the New Madrid rift system and the increased seismicity of the eastern United States.

    The governor of Mazandaran said the decision to close all Mazandaran entrances to prevent coronary heart disease and protect the health of residents of the province, as well as travelers and tourists themselves, was made after school and university holidays were announced and will continue until the end of the Nowruz holiday.

    Mahdavi emphasized that “only fuel-powered vehicles and foodstuffs are allowed to enter Mazandaran at the moment” and urged all those planning to travel to Mazandaran not to abandon their journey and not enter the Mazandaran roads.

    At the same time, the governor of Savadkoh announced that the city’s entrance from Tehran was tightly controlled and that travelers were not allowed to enter the province.

    Mazandaran governorate officials said the decision to close all Mazandaran entrances was based on a decision by the provincial headquarters to deal with the Corona virus and that “all Mazandaran access routes for travelers and non-indigenous people” were closed.

    Hours before the closure of the roads of Kandovan, Haraz and Firouzkouh, also at 5am on Thursday 15 March, according to the decision of the Mazandaran Coronavirus Prevention and Control Headquarters, the province also has closed access routes from Gilan to Ramsar in the westernmost part of Mazandaran province. Was.

    Ramsar’s governor, Mohammad Azad, confirmed that all entrances to the city would be closed, “to prevent the spread of coronaviruses until secondary information would prevent travelers from entering Ramsar.”

    About three weeks ago on February 30, when the Iranian Ministry of Health formally confirmed the outbreak of coronation in Qom and announced that two people had died of coronation in Qom, in addition to a number of people and media activists, a number of representatives The parliament also called for the quarantine of Qom to be controlled and exiled, but officials at the health ministry, senior clerical officials and government officials opposed the quarantine as Qom a global religious city.

    After that, in less than three weeks, the Corona virus spread to all four provinces of Iran, and now hundreds of cities in Iran and thousands of Iranians in large and small cities are hospitalized because of the virus, according to sources. According to Iranian International, the death toll from coronation in the country has reached at least 3 people.

    Mazandaran officials said they decided to close all entrances in the province on Thursday evening, after thousands of schools in Tehran moved to Mazandaran following the closure of schools and universities until the end of the Nowruz holiday, citing concerns of people in Mazandaran province. This worsened the incidence of coronary heart disease and the likelihood of aggravating the disease in Mazandaran. The figure in Iran for Corona Virus is false 2650 died and over millions infected.

  2. Tea tree oil is a decongestant against viral mushroom spores inhaled. Caronavirus resembles the Spore of a mushroom. Sniff Tea tree oil. There’s a good boy.

  3. The problem is we do not have Israeli Masks. We need such masks really stay healthy. Should we all go to Israel . Why our North America including Canada must not be ready . Supermarkets every one touch tomatoes , fruits pretty much anything before buy. Do you think the virus will not mutate which already done so. 2 strains of COVIOD-19 now weak one and stronger one.Why food shortages and medicine shortages keep North America as third world country? We can not accept that the hospitals are ready for 100 Millions COVOID-19? No way?
