Full title and description

SN RK 2.03-28-2004 — Scale for evaluation of earthquake intensity MSK-64(К). National Kazakhstani construction norm that defines procedures, criteria and tables for assessing earthquake intensity using the MSK-64 scale adapted (MSK-64(K)) for use in territorial surveys, post-event damage assessment and seismic microzoning.

Abstract

This document provides an adapted version of the MSK-64 seismic intensity scale (designated MSK-64(K)) with guidance and quantitative criteria for assigning intensity values based on: observed damage to buildings and structures, reaction of people and the environment, natural phenomena and instrumental data. It includes building-type classifications, damage-degree definitions, numeric thresholds and tables to support consistent intensity estimation for seismic zoning, emergency assessment and engineering use.

Scope

Defines procedures and criteria for evaluating earthquake intensity within the range commonly used for damage and engineering assessment (practically used for intensities from about 3 to 10 points). The scale is intended for: post-earthquake field assessments based on building damage and human/environmental observations; interpretation of instrumental records into intensity values; input to seismic microzoning and mapping; and for informing normative requirements in seismic design and emergency planning.

Key topics and requirements

• Adaptation of the MSK-64 intensity scale (MSK-64(K)) for Kazakhstan conditions.
• Classification of building types by seismic resistance (types A, B, V / variations for masonry, timber, reinforced concrete, panel, etc.).
• Definitions of damage degrees (0 — no visible damage through progressive degrees up to catastrophic destruction) with quantitative descriptors for each degree.
• Procedures to estimate intensity from observed building damage and from human/environmental reactions (people, furniture, ground effects, natural phenomena).
• Tables and rules to convert instrumental ground- and building-motion parameters into intensity estimates.
• Guidance on use of the scale for seismic zoning, microzoning and post-event reporting.

Typical use and users

Used by seismologists, structural and geotechnical engineers, emergency-management and civil-protection personnel, municipal and regional planning authorities, post-earthquake reconnaissance teams, insurance and risk-assessment professionals, and researchers performing seismic microzoning or damage studies. Typical uses include post-event intensity mapping, input for seismic hazard and risk assessments, and reference when preparing or updating seismic design/normative documents.

FAQ

Q: What is this standard?

A: SN RK 2.03-28-2004 is a Kazakhstani construction norm that defines the MSK-64(K) scale and procedures for assessing earthquake intensity by observing building damage, human reactions, natural effects and instrumental measurements.

Q: What does it cover?

A: It covers classification of building types and damage degrees, quantitative descriptors and tables for assigning MSK-64(K) intensity values, methods to estimate intensity from instrumental parameters, and guidance for using intensity estimates in seismic zoning, mapping and post-earthquake reporting.

Q: Who typically uses it?

A: Seismologists, structural and geotechnical engineers, emergency responders, municipal planners, reconnaissance teams, insurers and researchers involved in seismic hazard assessment, damage evaluation and seismic-aware planning.

Q: Is it current or superseded?

A: The document was approved on 14 September 2004 (Order No. 371). It has been used as the national reference for intensity assessment; however, national construction and seismic regulations are periodically updated. Users seeking the definitive current legal status or any amendments should verify with the official national regulatory registry or the responsible Kazakhstani authorities before relying on the standard for regulatory compliance or design decisions.

Q: Is it part of a series?

A: Yes — it belongs to the SN RK 2.03.* series of norms addressing protection and construction in relation to geophysical (seismic) hazards and sits alongside other SN RK and SNiP/SN RK documents covering seismic design, microzoning and engineering protection measures.

Q: What are the key keywords?
