regenerate and get stronger again. so we re going to have a formidable storm next weekend with a possible landfall on september 11. but we re watching this as you can see day by day. it s going to take a while. we ve got a good handle on this. i was talking to friends in haiti who were saying they hope it goes north. if it stays over water and misses all those islands, it will likely increase in strength then. yeah. we re going to see what s called an eyewall replacement cycle. that takes 10 to 12 hours. but we could see two or three of these occur. most likely it will be a major category, 3, 4, 5 for the southeastern u.s. tom, there were reports that the storm is so strong, it s showing up on seismometers. can you show us why? the eye of the storm is about 23 miles in diameter.
seismometers? can you explain why this is happening, what the significance is? this is really interesting. let me show you a radar that s out of martinique in quad loupe. the eye of the storm is 23 miles in diameter. looks like it s going to swallow barbuda and anguilla. seismic activity in guadalupe. it s not something you d feel on the ground. but there are slow tremors being picked up by seismographs. it s basically, because of the winds, because of the sound, believe it or not, the winds that are coming in already hitting the trees and that energy is going down to the ground right now. so it s going to increase a little bit. but it s happened before, we even had reports of it in texas with harvey. tom, appreciate it. next to laila santiago, what conditions are expected in the hours ahead? well, we are starting to feel the winds really picking up here on the northern part of the island, abandnderson.
it has to be both carrots and sticks. and so whatever conversations president trump is having with president xi, i would assume includes a conversation related to, listen, we can cooperate on x, y, z, probably something completely unrelated, but also, if you don t cooperate, i m going to sanction whichever banks and freshry is going to know which banks. they had a 45-minute conversation, so perhaps they got to some of that stuff. always great to have you here. pleasure to talk to you both. one of these days we ll all get to talk about something that s not bad news. all right. coming up, hurricane irma, it is so strong it s showing up on seismometers, which are actually designed to measure earth cakes. this dhing is really, really strong. we re going to take you live to puerto rico where people are bracing themselves for dangerous rain and storm surges. they re experts in things you haven t heard of - researchers of technologies that one day, you will.
earthquake on there, will create waves that have to propagate a longer distance and therefore they die down a little bit as opposed to the punt at that hills thrust which lies right underneath downtown los angeles and waves don t have far to travel at all. bill: when you get so many shakers over the past seven days, are you more alert? are you looking at different things now this week or other seismologists looking are their antenna up based on what we watched last week? i would say, to a small degree but i don t think most of us think this is indicates anything imminent coming necessarily. one thing we are trying to do in california is have what s called an early warning system where systems of seismometers will be laid out in various places and give warning perhaps, 10 or 30 seconds incoming strong shaking. that is something we d like to do here and, but at the moment we don t have the funding for
