SummaryThe local magnitude ML at the seismological station Pruhonice (PRU) was converted into surface wave magnitude MS using the formula MS=−3.2+1.45 ML and the seismic wave energy was estimated using the relation log E (Joule)=1.2+2.0 ML. It was proposed to apply the same conversion formulae at seismological stations Kašperské Hory (KHC) and Berggiesshübel (BRG) where the calibrating functions for local magnitudes were determined for the same set of earthquakes with common reference… 

Relations for local magnitude at seismic station Berggiesshübel

SummaryNew calibrating functions for the local magnitude ML based on the maximum ratio of amplitude and period of the Sg - wave, the short-period surface wave and the duration of the whole seismogram

Ionospheric anomaly due to seismic activities-III: correlation between night time VLF amplitude fluctuations and effective magnitudes of earthquakes in Indian sub-continent

Abstract. We present the results of an analysis of year-long (2007) monitoring of night time data of the VLF signal amplitude from the Indian Navy station VTX at 18.2 kHz, received by the Indian


We present first results of the study of possible relations between the seismic activity and crustal fluids (groundwater and carbon dioxide) in the area of the Hronov-Pořici Fault Zone (HPFZ),

Precursory groundwater level changes in the period of activation of the weak intraplate seismic activity on the NE margin of the Bohemian Massif (central Europe) in 2005

AbstracttWe analyse continuous measurements of groundwater level in two deep wells VS-3 and V-28 at the experimental hydro-meteorological station situated on the NE margin of the Bohemian Massif,

Monte Carlo Based Seismic Hazard Model for Southern Ghana

Seismic hazard assessment involves quantifying the likely ground motion intensities to be expected at a particular site or region. It is a crucial aspect of any seismic hazard mitigation program. The

Poisson hidden markov model on earthquake occurrences in Metro Manila, Philippines

The Philippines, as part of the Circum-Pacific belt, is considered as one of the most seismically active countries in the world. Earthquake occurrence is frequent and its effects vary depending on

Seismic activity in the region of northwest bohemia

SummaryThe seismic activity of the region is analysed on the basis of the recent microseismic and former macroseismic observations. Only microearthquakes in the narrow magnitude range of 0–1.2 were



Seismic moment, stress, and source dimensions for earthquakes in the California‐Nevada region

The source mechanism of earthquakes in the California-Nevada region was studied using surface wave analyses, surface displacement observations in the source region, magnitude determinations, and

Earthquake magnitude, intensity, energy, and acceleration

The magnitude of an earthquake was originally defined by the junior author (Richter, 1935), for shocks in southern California, as the logarithm of the maximum trace amplitude expressed in

abstract A magnitude scale has been developed for South Australian earthquakes which is simple and consistent. It is based on the maximum trace amplitude among the S waves recorded on vertical

Source parameters of southern California earthquakes

The source characteristics of southern California earthquakes with local magnitudes ML between 2 and 7 have been estimated from the gross spectral properties of the locally recorded S waves written

Magnitudes and travel-time residuals of the Friuli earthquakes between May and August 1976

SummaryThe records of the first series of the North-Italian aftershock series from the period May–August 1976 at the stations Průhonice and Kašperské Hory were analyzed from the point of view of the

Regional seismicity and seismic wave propagation from records at the Tonto Forest Seismological Observatory, Payson, Arizona

The records of the Tonto Forest Seismological Ohservatorynear Payson, Arizona, have been used to investigate the applicabilityof an array station for the study of locai seismicity and seismic wave

Source parameters and scaling laws of the 1978 Swabian Jura (southwest Germany) aftershocks

The 3 September 1978, Swabian Jura (southwest Germany) earthquake (MWA = 5.7) was followed by a large number of aftershocks which have been recorded with a local network of five portable seismic

Earthquake magnitude, intensity, energy, and acceleration(Second paper)

This supersedes Paper 1 (Gutenberg and Richter, 1942). Additional data are presented. Revisions involving intensity and acceleration are minor. The equation log a = I/3 − 1/2 is retained. The

A microearthquake swarm in 1965 near Mould Bay, N.W.T., Canada

In a 30-day period beginning March 29, 1965, some 2026 microearthquakes were recorded at MBC and by the array NPNT. About 10 per cent of them were located. The extent of the epicentral region was 3
