Because of the depth and magnitude, there was a low chance for a local tsunami as well (but we have been surprised before). I could not identify a tsunami on the tide gages in the region.<\/p>\n<p>However, the USGS One Pager PAGER alert suggests that there may be significant casualties. I hope this estimate is incorrect. I have seen some videos online of significant building damage.<\/p>\n<p>The USGS prepares models to estimate the chance of earthquake triggered landslides and earthquake induced liquefaction. These models suggest that there is a low chance for landslides but a moderate chance for liquefaction. See the ground failure section of the USGS earthquake page for more information.<\/p>\n<p>I don\u2019t always have the time to write a proper Earthquake Report. However, I prepare interpretive posters for these events.<\/p>\n<p>Because of this, I present Earthquake Report Lite. (but it is more than just water, like the adult beverage that claims otherwise). I will try to describe the figures included in the poster, but sometimes I will simply post the poster here.<\/p>\n<h2><font color=\"orange\">Below is my interpretive poster for this earthquake<\/font><\/h2>\n<ul>\n<li>I plot the seismicity from the past month, with diameter representing magnitude (see legend). I include earthquake epicenters from 1923-2023 with magnitudes M \u2265 6.5. <\/li>\n<li>I plot the USGS fault plane solutions (moment tensors in blue and focal mechanisms in orange), possibly in addition to some relevant historic earthquakes. <\/li>\n<li>A review of the basic base map variations and data that I use for the interpretive posters can be found on the <a href=\"http:\/\/earthjay.com\/?page_id=3218\" rel=\"noopener\" target=\"_blank\">Earthquake Reports page<\/a>. I have improved these posters over time and some of this background information applies to the older posters.<\/li>\n<li>Some basic fundamentals of earthquake geology and plate tectonics can be found on the <a href=\"http:\/\/earthjay.com\/?page_id=8202\" rel=\"noopener noreferrer\" target=\"_blank\">Earthquake Plate Tectonic Fundamentals page<\/a>.<\/li>\n<\/ul>\n<ul>\n<h3><font color=\"orange\">I include some inset figures. <\/font><\/h3>\n<li>In the upper left corner is a large scale plate tectonic map showing the major plate boundary faults.<\/li>\n<li>In the lower left center is a map showing how the Nazca slab is configured in different locations (Ramos and Folguera, 2009).<\/li>\n<li>In the left center is a cross section showing seismicity in this region (Kirby et al., 1995). The source area for this plot is designated by a dashed yellow box on the map.<\/li>\n<li>In the upper right corner is a pair of maps that show the landslide probability (left) and the liquefaction susceptibility (right) for this M 6.8 earthquake. I spend more time describing these types of data here. <a href=\"http:\/\/earthjay.com\/?p=8541\" rel=\"noopener\" target=\"_blank\"><\/a>Read more about these maps <a href=\"https:\/\/earthquake.usgs.gov\/data\/ground-failure\/background.php\" rel=\"noopener\" target=\"_blank\">here<\/a>. <\/li>\n<li>In the lower right corner I plot the USGS modeled intensity (Modified Mercalli Intensity scale, MMI) and the USGS &#8220;Did You Feel It?&#8221; observations (labeled in yellow). Above the map is a plot showing these same data plotted relative to distance from the earthquake.
