250th Anniversary of the 1755 Lisbon Earthquake
A probabilistic method that takes account of the ordinal character of the MSK Scale has been adapted to generate a 1755 seismic intensity map for the Iberian Peninsula. Statistical models are employed to estimate isoseismals and to compute standard error uncertainties. The output includes intensity maps, estimates of the effects associated with each intensity level, and estimates of the distrib...
متن کاملA Statistical Study of the Seismic Intensities of the 1755 Lisbon Earthquake
Substantial tragic effects result from great earthquakes – damage, deaths, tsunamis. Various groups, including seismologists, seismic engineers, government officials and insurers seek to quantify the effects in order to proceed with their work. The quantification methods employed include seismic intensity scales and damageability matrices particularly. Principal intensity scales employed are: t...
متن کامل250TH ANNIVERSARY OF THE 1755 LISBON EARTHQUAKE Seismic risk evaluation for an urban centre
Risk has been defined, for management purposes, as the potential economic, social and environmental consequences of hazardous events that may occur in a specified period of time. However, in the past, the concept of risk has been defined in a fragmentary way in many cases, according to each scientific discipline involved in its appraisal. From the perspective of this article, risk requires a mu...
متن کامل250TH ANNIVERSARY OF THE 1755 LISBON EARTHQUAKE Evaluation of the risk management performance
The Risk Management Index, RMI, brings together a group of indicators that measure risk management performance and effectiveness. These indicators reflect the organizational, development, capacity and institutional actions taken to reduce vulnerability and losses, to prepare for crisis and to recover efficiently from disasters. This index was designed to assess risk management “performance”. It...
متن کاملSource mechanism of February 4, 1965, Rat Island earthquake
The Rat Island earthquake of February 4, 1965 (origin time 05h 01m 21.8s, h = 40 km), is one of the largest earthquakes recorded in recent years. On the basis of the radiation patterns and the amplitudes of the great circle Rayleigh and Love waves, the earthquake is found to have the following characteristics: fault plane dip, 18ø; fault plane dip direction, N19øE; rupture propagation direction...
