    We need concern for California's San Andreas fault activities around its extremely overpopulated communities, and the New Madrid Siesmic Zone that is highly expected to soon cause another massive earthquake in the Mississippi River valley near the central Ozark Mountains area and possibly affecting Illinois, Indiana, Missouri, Arkansas, Western Kentucky, Western Tenessee, and/or Northwestern Mississippi.

    Earthquakes in this area have been recorded since 1811: an earthquake greater than magnitude 8 occurred along the Mississippi River valley near New Madrid, Missouri and Blytheville, Arkansas in 1811-1812; another 6.7 in Missouri in 1895; and a few magnitude 7 earthquakes have been very recently recorded in Illinois and Indiana.

    As a fascinating interesting side-note: "The New Madrid Seismic Zone is made up of reactivated faults that formed when North America began to split or rift apart during the breakup of the supercontinent Rodinia in the Neoproterozoic Era (750 mya). The rift failed, but remained as a scar or zone of weakness."

    The Saint Francois Mountain Range in the central Ozark Mountains rise above the Ozark plateau and are the remains of a Precambrian mountain range. The core of the range originally existed as an island in the Paleozoic seas.

    "This range is one of the oldest exposures of igneous rock in North America....Formed through volcanic and intrusive activity over 1.4 bya, nothing is left of these mountains but the roots. By comparison, the Appalachians started forming about 460 mya, and the Rockies a mere 70 mya. When the Appalachians started forming, the St. Francois range was already twice as old as the Appalachians are today.

    Unlike the rest of the mountainous areas in the Ozarks, the Saint Francois Mountains were formed by true volcanic activity. The localized vertical relief observed in most of the Ozarks, a dissected plateau, was caused by erosion. The volcanic activity that formed this mountain range is also thought to be the geological cause of the uplift of the Ozark Plateau. Geologists talk of the "Ozark dome" wherein elevations and stratigraphic inclines generally radiate down from the Saint Francois mountains. These elevations may be the only area in the American Midwest never to have been submerged, existing as an island archipelago in the Paleozoic seas. Fossilized coral, the remains of ancient reefs, can be found among the rocks around the flanks of the mountains. These ancient reef complexes formed the localizing structures for the mineralizing fluids that resulted in the rich ore deposits of the area."

    No apology necessary.
    You do realise that posting the words 'Locked' or 'This forum is locked' carry absolutely no weight, unless you happen to be a moderator or admin and have the power to lock a thread. What are you hoping to achieve by such actions. Genuinely puzzled.

    mod means moderate: "not excessive or extreme," or else modern.

    Thanks for the complement, I do try not to be excessive or extreme unless of course there is a justifiable cause worth fighting for, else what's the point. Waste of effort and time, right? Who plays with sticks or swords? Again, waste of time and effort -mentality of the Middle Ages.

    In this context, "mod" means a moderator of the forums, ie a user with the power to lock threads and edit posts in one or more subforums.
