and geographic coordinates (lat, lon) -5.28, 153.682 at 18 km depth.

The earthquake was located by: Sala Sismica INGV-Roma.

Search earthquakes: Any within 30 km radius

The values of hypocentral coordinates and magnitude may be revised at a later time as more information becomes available.

Municipalities with at least 50000 inhabitants

No Italian municipalities within 100 km from the epicenter with at least 50000 inhabitants.

Recent and historical seismicity
Seismic hazard
Shakemap

These three maps show the results of the analysis using the software ShakeMap designed to provide the level of ground shaking experienced in a region using the data recorded by seismometers and strong motion instruments and seismological information regarding the attenuation of the wavefield with distance and the site characteristics. The Shakemaps are determined for research purposes to provide fast estimates of the level of ground shaking produced by the earthquake. The maps are calculated automatically and updated as more data become available. See http://shakemap.ingv.it for additional information. The black star indicates the epicenter. The triangles show the accelerometric and velocimetric stations used in the calculation, colored according to the recorded shaking.

Intensity Shakemap

Intensity Shakemap

This map shows the distribution of instrumental intensities. The intensity is derived through an empirical law that correlates the recorded values of actual ground shaking, e.g., acceleration and velocity, with the macroseismic intensity for Italian earthquakes, as reported in the Italian Macroseismic Database (DBMI15, https://doi.org/10.13127/cpti/cpti15.3).
Peak ground acceleration Shakemap

Peak ground acceleration Shakemap

This map shows the distribution of peak ground acceleration expressed as percent of the acceleration of gravity (i.e., g = 9.81 m/s²).
Peak velocity Shakemap

Peak velocity Shakemap

This map shows the distribution of peak ground velocities expressed in cm/s.
Felt maps
Preliminary map of the earthquake effects from the web questionnaire

Preliminary map of the earthquake effects from the web questionnaire

This map shows the distribution of earthquake resentment in the area, expressed in terms of intensity on the MCS scale (Mercalli-Cancani-Sieberg). Intensities are determined using data from questionnaires collected on the website http://www.hsit.it. The intensities shown are determined considering all the reports received from each municipality, and are all the more reliable the greater the number of questionnaires. The collected data are subjected to an automatic statistical filter, but are not checked individually. In particular, intensities greater than or equal to the VI degree of the MCS or EMS scale require on-site verification by specialized personnel. The black star is the epicenter of the earthquake that occurred. This map is updated every time citizens fill out new questionnaires. The number of questionnaires processed to obtain this map, the date and time of the last update are shown at the top right.
