The Effect of Confinement Due to COVID-19 on Seismic Noise in Mexico

Featuring Dr. Xyoli Pérez-Campos

In this session, special guest speaker Dr. Xyoli Pérez-Campos will discuss effects on seismic noise related to COVID-19 lockdowns in Mexico.

Mexican seismic stations witnessed a reduction in noise level as a result of the lockdown strategies to contain COVID-19. The largest drop was observed in Hermosillo, also the city with the fastest noise level recovery, and a quick increase in confirmed COVID-19 cases. Since June 1, 2020, a traffic-light system modulates the re-opening of economic activities for each state, which is reflected in noise levels. Noise reduction has allowed the identification and perception of smaller earthquakes.

This informative webinar + Q&A is a must-see for anyone interested in how other factors can impact seismic observation.

Review of Recent Applications of Ambient Noise Surface Wave Tomography (ANSWT)

Featuring Dan Hollis

Ambient seismic noise surface wave tomography for subsurface imaging and monitoring was developed in the early 2000s. Application of the method started with crustal studies and has evolved over the past several years to several applications: seismic hazard assessment, mineral exploration and development, Oil/Gas/Energy exploration and development, geotechnical assessment, and geothermal exploration and development.

In this session, special guest speaker, Dan Hollis will present a review of the ANSWT method and review several imaging and monitoring projects performed over the past couple of years.

Surface Wave Methods for Seismic Site Characterization

Featuring Dr. Sebastiano Foti 

Surface wave methods gained in the past decades a primary role in many seismic projects. Specifically, they are often used to retrieve a 1D shear wave velocity model or to estimate the VS,30 at sites of strong motion networks. The complexity of the interpretation process and the variety of possible approaches to surface wave analysis make it very hard to set a fixed standard to assure quality and reliability of the results.

In this session, special guest speaker Dr. Sebastiano Foti will introduce us to surface wave analysis and summarize the InterPACIFIC (Intercomparison of Methods for Site Parameter and Velocity Profile Characterization) guidelines published in 2018 and will provide some application examples.

Bridging Technology and Policy: The Case of Earthquake Early Warning Systems in the 2030 Agenda

Featuring Dr. Jair Torres

Bridging Technology and Policy: The Case of Earthquake Early Warning Systems in the 2030 Agenda

Earthquake and Multi-Hazards Early Warning Systems (EWS) ) disseminates timely information about the eminent impact of hazards to the public, emergency responders, and managers in the public and private sector, providing time to implement emergency measures, including some automatically.

In this session, special guest speaker Dr. Jair Torres will discuss how recent international agreements such as the Sendai Framework for Disaster Risk Reduction (SFDRR) 2015–2030, the 2030 Agenda for Sustainable Development, the Paris Agreement, and the New Urban Agenda, have all recognized the importance of EWS in moving the development agenda forward.

This informative webinar + Q&A will focus on the challenges and opportunities of turning current technologies on Earthquake EWS into practice and policy.

Earth’s Rock ‘n’ Roll – Measuring Rotational Motions in Seismology

Featuring Professor Heiner Igel 

We all know that seismology is a science based on measuring ground motions using seismometers. This measures three components of translational motions. But is that all the ground does? No, there are other motion components.

In this session, special guest speaker Professor Heiner Igel will discuss new developments in seismic instrumentation – in particular rotation sensing – with applications ranging from earthquake physics, ocean bottom seismology, seismic tomography, volcanology, earthquake engineering to planetary seismology. The key to these new applications is optical technology making use of laser light and relativistic effects getting hold of the wavefield gradient related information.

This informative webinar + Q&A is a must see, focusing on concepts and results from innovative pilot projects.
