we re talking as far away as 400 miles people felt some kind of shaking. this area is where people felt strong or severe shaking. again, that violent shaking in buildings, in homes, in other types of infrastructure that s really throughout many of those locations. again, we talked about it. here is a look. this is what we call the si seismograph. that s how we can gauge the scale here of terms of how long this actually took. again, we figure it took about a minute and a half give or take. the initial quake here being a 7.0, depth of about 40 kilometers. that s give or take about 25 miles. that may seem that it s very deep to you, but in terms of earthquake terms, it really isn t. anything 70 kilometers and less
ca quake. a sinkhole out at the gate where she lives. gavin, i want to get into her point about feeling those aftershocks. 7.0 magnitude, put that in perspective for us. it s pretty large. because it s pretty close to anchorage, about 40 kilometers deep and about 10 kilometers to the north. i think people in the anchorage area felt it so, so deeply is because it was so close to them in ways that maybe other earthquakes were not. how far out did people feel this? do you know? i don t know offle top of my head. probably it would have been
7, you could get one that s 6.0 or higher after a quake like this. the concern going forward for a lot of these people is really going to be those after shocks. they just had a 7.9 in january. why does this feel so much worse? it could be a couple of different factors. that one could have been significantly deeper, could have been farther away from the communities where these people live. the deeper an earthquake, the less likely i don t know where those specific people live in reference to that previous one. there s a lot of factors involved. this one was really close to downtown. you d likely have a lot more people those typically will cause significant damage. this one lasted about a minute
right. i just didn t understand because it was going perfectly fine up until then and it felt like the ground was going to open up underneath you. lights were flashing, it was very dark. it was crazy. and the aftershock, we re up to counting 16, are they just blips compared to that initial earthquake? can you feel them? we can feel most of them. i felt the very first aftershock right as i crossed over the bridge that is now closed. and it felt like another earthquake. but we have felt several shakes just kind of sitting on the couches, keeping up with cnn. the aftershocks are terrifying because you don t know if they re going to be small or if there s going to be another big quake. melissa lohr, southerner in alaska experiencing her first
