A map from the 2018 United States Seismic Hazard Model showing highest hazard in red and lowest hazard in gray. Damage from various earthquakes around the U.S. is shown in the photographs. Larger versions of each photo can be found at: 2001 M6.8 Nisqually, Washington, 2014 M6.0 South Napa, California, 1994 M6.7 Northridge, California, 1975 M7.7 Kalapani, Hawaii, 2011 M5.8 Mineral, Virginia, and 2018 M7.1 Anchorage, Alaska.maps - The 2023 Modified Mercalli Intensity (MMI) hazard maps of the conterminous United States showing estimates of earthquake shaking in terms of (1) 50% probability of exceedance (PE) in 50ā€‰years (somewhat likely), (b) 10% PE in 50ā€‰years (uncommon), and (c) 2% PE in 50ā€‰years (rare).maps - Maps show faults, zones applied in the CEUS, and zones of ground-motion model (GMM) amplification for the 2023 50-State National Seismic Hazard Model. The inset map is a close-up view of the New Madrid seismic zone area (orange dashed boundary). Spatial boundaries include potentially induced earthquakes for the update and the previous 2018 zones, 2023 central and eastern United States (CEUS)ā€“western United States (WUS) attenuation boundary update and 2018 boundary, WUS basins, and two areas of uniform seismicity. Fault sections for the WUS (Hatem et al., 2022a, 2022b) and for Alaska from Bender et al. (2021) are shown colored according to slip rates. Fault sections in the CEUS are not shown according to slip rates but all slip rates are less than 0.2ā€‰mm/year. The Alaska megathrust is represented by 14 segmented zones. Damaging earthquake locations are shown in all three maps. In addition, we show seismicity for Alaska (M7+) and Hawaii (M5+) (Petersen et al., 2021; Rukstales et al., 2021)....maps and charts - Normalized probability density function grids of seismicity-based earthquake rates (no fault models) are displayed for (a) the western United States (WUS), (b) the central and eastern United States (CEUS), (c) Alaska, and (d) Hawaii...

#Taiwan was hit by a Magnitude 6.2 #earthquake earlier today.

My computer jumped into alert mode with the Earthquake Early Warning app with more than 20 seconds to spare. I gave everyone in the office a heads-up of the incoming #tremor.

Thankfully it ended up just an Intensity 2 quake on the CWB scale (Level III on the Modified #Mercalli scale) in #Taipei.

If you live in Taiwan, this app is a 10 out of 10 recommendation from me.

Screenshot of the Earthquake Early Warning app simulating the Magnitude 6.2 earthquake off the coast of Hualien County, Taiwan, on December 15, 2022 at 12:03 local time. The app indicated an Intensity 3 quake would arrive at the current location in 26 seconds. A color-coded map shows the epicenter, animated expanding rings of the two incoming shockwaves (both the P wave/compressional wave and the S wave/shear wave), as well as the predicted intensity felt across different parts of Taiwan.
