A magnitude 6.1 earthquake struck south-central China near Dali on May 21, 2021 at 9:48 pm local time (May 21 at 13:48 UTC) followed by a magnitude 7.3 on May 22 at 2:04 am local time (May 21 at 18:04 UTC). Seismic instruments indicate both earthquakes originated at a depth of 6.2 miles (10 kilometers).

Coastal Change Hazards researchers Dr. Legna Torres-Garcia and Dr. Donya Frank-Gilchrist of the St. Petersburg Coastal and Marine Science Center (SPCMSC) organized a joint meeting with principal investigators currently conducting hazards-related projects in Puerto Rico. 

After 15 years of planning and development, the ShakeAlert earthquake early warning system is now available to more than 50 million people in California, Oregon and Washington, the most earthquake-prone region in the conterminous U.S.

For Women’s History Month in March 2021 the @USGS_Quakes Instagram featured dozens of photos of female earthquake scientists and shout-outs with the hashtag #EarthquakeWomen from the Earthquake Science Center, Geologic Hazards Science Center and the Office of Communications and Publishing (OCAP).

The U.S. Geological Survey (USGS) is currently soliciting project proposals for Fiscal Year (FY) 2022 grants on earthquake hazards science and is authorized to award up to $7 million. The deadline for applications is June 1, 2021, and interested researchers can apply online at GRANTS.GOV under funding Opportunity Number G22AS00006. 

In this issue: When will Mauna Loa next Erupt?, ShakeOut rollout to the Pacific Northwest, Big Sur Landslides, new storymaps for earthquakes and wildfire science, expanding coverage of the "Total Water Level and Coastal Change Forecast" tools, New Reducing Risk 2021 projects, and more.

Through coordinated communication activities, the Natural Hazards Mission Area is committed to sharing news and science with broad audiences. Social media is an important part of this communications portfolio.

Can a deep-learning approach perform better than NEIC’s traditional methods to get more accurate earthquake locations and magnitudes? The NEIC monitoring system is a perfect candidate for deep learning because it processes large amounts of data, and that’s where deep learning excels.
