Earthquake Resilience in Hospitals: OasisPlus Case Studies 

Featuring Dr. Derek Skolnik, Kinemetrics

When an earthquake strikes, the focus of concern quickly turns to critical infrastructure and services. Chief among these is access to healthcare facilities and the services they provide. It’s imperative that these regional hubs remain in operation as the community’s need for hospitals increases during and after a seismic event.

In this informative webinar + Q&A, Dr. Derek Skolnik will review how two hospitals in areas with high seismic activity have implemented the use of real-time earthquake response systems and procedures. He will outline how these organizations have built resilience into each aspect of their respective implementations to ensure access to critical decision-making information before, during, and after an event. Suggestions on how similar critical organizations can learn from these implementations will also be provided.

Non-Invasive Subsurface Site Characterization for Seismic Ground Response Analyses

Featuring Dr. Brady Cox, Utah State University

The importance of accurately predicting site effects for engineering infrastructure projects in seismically active regions cannot be overstated.

Numerical earthquake wave propagation simulations, known as ground response analyses (GRAs), are commonly performed in an attempt to estimate the site-specific, frequency-dependent amplification of seismic waves (i.e., site effects) as they travel from a reference bedrock condition up through soil layers to the ground surface.

One-, two-, and three-dimensional (1D, 2D, and 3D) GRAs have been developed. However, recent studies have revealed that recorded ground motions at more than 50% of borehole array sites are modeled using 1D GRAs. While 3D GRAs are theoretically plausible, they remain largely inaccessible due to a lack of adequate and affordable site characterization methods that can be used to develop 3D subsurface shear wave velocity (Vs) models down to depths required for ground response studies.

In this presentation, Dr. Brady Cox will detail several seismic site characterization methods usable in developing subsurface models for use in 1D, 2D and 3D GRAs. Dr. Cox will discuss methods such as horizontal-to-vertical spectral ratios (HVSR or H/V) of ambient noise, multi-channel analysis of surface waves and microtremor array measurement.

Additionally, a new geostatistical approach that can be used for building large pseudo-3D Vs models as a means to rationally account for spatial variability in GRAs will be presented. Each of these methods will be discussed from the perspective of case history applications, including comparisons between recorded and GRA-predicted ground motions at several borehole array sites.

Seismic and Structural Health Monitoring of Large Concrete Dams

Seismic and Structural Health Monitoring of Large Concrete Dams  |  Featuring Dr. André Alegre, Instituto Superior de Engenharia de Lisboa (ISEL) and National Laboratory for Civil Engineering (LNEC)

Large concrete dams are civil engineering structures of vital importance for the management of freshwater resources, including water supply and hydropower. They are generally associated with high potential risks, and it is critical to continuously evaluate their dynamic behavior in normal operating conditions, enabling the analysis of measured vibrations under ambient/operational excitations, for structural health monitoring, and to analyze the response during earthquakes. Studies on the dynamic behavior of large concrete dams should be conducted based on results from dynamic monitoring data and numerical results obtained using advanced finite element models.

In this session, special guest speaker Dr. André Alegre presents programs recently developed for improving the software component of Seismic and Structural Health Monitoring (SSHM) systems of large concrete dams and for dynamic behavior modelling.

In this informative webinar + Q&A, Dr. Alegre places particular focus upon the primary results from studies on the dynamic behavior of two large arch dams, which have been under continuous dynamic monitoring over the last 10 years.

A 10-Year Review of the Operation of the Mission Critical Italian Strong-Motion Network – RAN

KMI Information Series Webinar + Q&A!!!

The Italian Civil Protection Department (DPC) is the owner of the 500-station national Italian strong-motion network (Rete Accelerometrica Naczionale – RAN). Since 2012, DPC has outsourced the network maintenance and operation to Kinemetrics’ Open Systems & Services Division (OSS).

In this session, Dr. Mathias Franke will review the RAN performance from inception in 2012 to recent events spanning nearly ten years. The webinar highlights the dynamics of such a large network requesting constant improvements and the need for scalability. He will place additional focus on how the knowledge gained from the RAN is fed back into Kinemetrics’ Aspen Solution, e.g., software, hardware, and system design.

We look forward to seeing you there!

A New Way Of Maximum Magnitude Estimate for Induced Seismicity – Chaos

A New Way Of Maximum Magnitude Estimate for Induced Seismicity – Chaos

Traffic Light Systems (TLS) for induced seismicity by underground injections traditionally rely on magnitude thresholds. The choice of these thresholds is debated and found inappropriate, with most recent 2020 fashion proposing very low thresholds based on empirical observations.

In this session, Dr. Leo Eisner will demonstrate that these observations can be explained as order of statistics and show how this theory can be used for TLS.

We look forward to seeing you there!

The Value Of SHM To Manage Seismic Emergency

The Value Of SHM To Manage Seismic Emergency

The management of civil infrastructures in the aftermath of a seismic event is a concern for decision makers, which have to choose quickly among alternative actions with limited knowledge on the actual structural conditions. Structural Health Monitoring (SHM) information can support these decisions.

However, information come with a cost and the relevant benefit must be assessed before the acquisition of the SHM system is decided.

In this session, Professor Maria Pina Limongelli will introduce us to the Value of Information (VoI) analysis, which is a powerful tool to estimate such benefit and to optimize the design of the SHM system for each specific application.

This informative webinar + Q&A presents a number of applications of VoI in the field of civil engineering for exemplary case studies.

We look forward to seeing you there!

The Importance of Force Balance Accelerometers to Constrain Future and Near Real Time Ground Motion Scenarios

The Importance of Force Balance Accelerometers to Constrain Future and Near Real Time Ground Motion Scenarios

Never before have so many strong motion instruments been deployed in the vicinity of active tectonic margins, which has enabled us to understand underlying physical processes of rupture that take place in the event of an earthquake. With the advancement of numerical and empirical techniques to simulate strong ground motion scenarios, with physics-based rupture models, the new objective is to constrain these models with ground motions recorded by force balance accelerometers, by dissecting the underlying physical processes related to the seismic source, path wave propagations, and site effects.

In this session, Dr. Jorge Crempien will show several approaches to invert these data to constrain kinematic rupture models on faults, for both scientific and near real time purposes, such as spatial ground motion intensities and cascading tsunami inundation estimations on coastal areas. He will also demonstrate numerical and empirical approaches aimed at constraining ground motion scenarios for regions with little recorded data.

This informative webinar + Q&A places particular focus on numerical methods to simulate ground motion stemming from crustal earthquakes, and the use of small earthquakes to simulate mega-earthquake ground motions on subduction zones, using the Empirical Green’s Function approach.

We look forward to seeing you there!

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

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

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.
