So I was thinking, aside from, you know, sales of Faberge eggs and Hummel figurines plummeting, how else has if affected daily life there in Reno? PESCA: Yeah, it seems like, you know, an inconvenience, bordering on something that could be dangerous. Some of moment magnitudes that have been calculated have gone up to about five, magnitude five, and residents did have some broken pipes and cupboards opening and all their glasses falling out, dishes falling out, still considered kind of minor damage. We have magnitudes for the Friday night one. DEPOLO: But that's about the extent of the damage through the 4.1 and 4.2. Slight, some cracking in some of the houses, like over doorframes. DEPOLO: Residents were losing plates and figurines off shelves. PESCA: And how big is a 4.2? Like, do plates fall off the shelf kind of thing, or how to we judge it? And then last week, on Thursday afternoon, we had two that were magnitude 4.1 followed by a 4.2 that were less than four minutes apart. And then, a couple weeks later, we started getting a few in the threes. And then we had those for a few weeks, and then we had some that were felt by residents that were still relatively small magnitude in twos. The upward trend, we started out with small-magnitude earthquakes, less than magnitude one. ![]() PESCA: So, if you were to chart them, they're not - each one is not necessarily bigger than the last, but in general, it's an upward slope? And we experienced our largest one of the sequence last Friday night. And this just is kind of weird because it's been going on, we're entering our third month right now, and these are the quakes started in February 21st, and they've been continuing. We, very often in Nevada, have larger earthquakes that are preceded by smaller earthquakes. ![]() PESCA: How weird is it to have slowly building, or maybe in varying degrees, all these little earthquakes, not followed by a big one, but maybe preceding a big one? But the largest out of the ones overnight from about 11 last night on were just before 11 and just after, they were high-magnitude-two to low-magnitude-three range. DEPOLO: I'm sure the residents that are right on top of them felt some of them overnight. ![]() PESCA: Enough to feel them if you were awake? And since then, I looked at the records this morning. We had a couple of about magnitude threes last night just before and after 11 o'clock local time. DEPOLO: Oh, actually, we were pretty quiet overnight. DIANE DEPOLO (Network Seismologist, Nevada Seismological Laboratory): Good morning. Diane dePolo is with the Nevada Seismological Lab in Reno. There are other characteristics to this earthquake sequence that have seismologists scratching their heads. Earthquakes usually feature aftershocks, not slowly building rumbles. Hundreds of earthquakes are rolling over the area, and they're growing in strength, which is weird. PESCA: For the past couple of weeks, Reno has been the shakiest little city in the world. It's very deep, so they haven't found it yet. ![]() NBMG was contracted by the Nevada Division of Emergency Management to update the hazard and mitigation sections and the assembly of the NEHMP, which resulted in a rapidĪdoption by FEMA.We should tell listeners that Mark has a chart near his desk called Squidlants, and I just hope we never the next biggest one, the ginormous squid. NBMG staff interact with emergency management personnel, as needed, and recently provided rapid response and situational monitoring during the January 2017 floods in western Nevada along the Truckee and Carson rivers and the Hawthorne earthquake sequence (three magnitude >5 earthquakes on Dec. Preparedness and Public Access NBMG provides state-of-the-art hazard and preparedness information to officials, emergency responders, and the Nevada public through the MyHazards-Nevada website, participation in the Nevada Resilience Commission and Western States Seismic Policy Council, and coordination of the update of the Nevada Enhanced Hazard Mitigation Plan (NEHMP).
