April 19 (UPI) A new forecasting model suggests an uptick in the frequency of magnitude 4 earthquakes along certain faults can predict large earthquake events of magnitude 6.7 or larger.
A few years ago, while studying seismic patterns along California s most active fault lines, a team of researchers led by Boston College seismologist John Ebel identified several faults that hosted an average of at least 0.5 magnitude 4 earthquakes per year from 1997 to 2016.
0 week. nation days away from default. still no deal. welcome to happening now. i m jon scott. good morning. good morning, everybody, i m arthel neville. i m in for jenna lee today. democrats and republicans remain far apart despite on going talks this weekend and anxiety growing on wall street. markets are in negative territory as we get closer to thursday s deadline to raise the debt ceiling. jon: illinois senator, dick durbin, the number two democrat in the senate, the two sides are roughly $70 billion apart. that is big money to most people. but on capitol hill they re looking to spend one trillion dollars give or take a bill. that is a million dollars a minute, every minute for a whole year. they re unable to agree on a deal to raise the debt limit, allowing the nation to pay its bills. a bipartisan group of 12 senators led by republican susan collins of maine and democrat joe manchin of west virginia is pushing a proposal to reopen the need to be lifted but the risk is not ze
we will certainly be looking for these kinds of patterns in more detail at other volcanos when they become active and not just volcanos in alaska but with, for instance, volcanos in the lower 48 states like mount st. helens as well as volcanos in iceland and japan and all throughout the world. jon: you don t have any there in boston, do you? we have no active volcanos in boston concern. jon: good. at least that we know of. jon: well, that s good. dr. john ebel, appreciate it. jenna: nice disclaimer. never know. jon: well, he s will in boston, wants to make sure he doesn t have anybody in the neighborhood that he s studying. jenna: well, he knows english but now only speaks swedish. his name is michael, but now he only answers to johan, and even though his license says he lived in florida and served in the navy, he has no memory of his former life at all. so what happened to this man who
admitted a series of emitted a series of low-pitched drum beats and rapid tremors which increased in frequency until the noise suddenly stopped just a minute or so before the volcano blew its top. here s what it sounds like sped up, scientists call it a volcanic scream. hear that? seismologist john ebel is director of the western observatory at boston college. this scream, it s only been te texted at this sol cato, right? is that because they weren t looking for it elsewhere or because it s the only volcano known to scream? well, actually, versions of this phenomenon where you see increases in earthquake activity and an amplification of the
