crashed car after earthquake of apr 6, 2009. This earthquake had a moment magnitude of 6.2 M W and a shallow focal depth ( ~8-9 km, according to the Istituto Nazionale di Geofisica e Vulcanologia, INGV, 2009: (1896-1977), Chinese Journal of Geophysics (2000-2018), International To open auxiliary materials in a browser, click on the label. The present observation that the Paganica fault is accommodating the extension in the central Apennines area (3–5 mm/yr according to D'Agostino et al. Due to the damage to the land, lots of the wildlife's, that inhabited L'Aquila, habitat was destroyed meaning they had no where to go. The 2009 L'Aquila earthquake occurred in the region of Abruzzo, in central Italy. 1). English: The 2009 L'Aquila earthquake was an earthquake of 6.3 moment magnitude that occurred on 6 April 2009 in the central Italian region of Abruzzo and claimed nearly 300 lifes. There had been many small tremors beforehand, starting in December 2008. To download, Right‐click and select “Save Target As…” (PC) or CTRL‐click and select “Download Link to Disk” (Mac). Table S2. and Chemical Oceanography, Physical The earthquake had an initial emergent onset followed by a more energetic pulse after about 1 second. The distribution of aftershocks, 712 selected events with ML ≥ 2.3 and 20 with ML ≥ 4.0, defines a complex, 40 km long, NW trending extensional structure. L’Aquila earthquake of 2009, severe earthquake that occurred on April 6, 2009, near the city of L’Aquila in the Abruzzi region of central Italy. - l'aquila stock-fotos und bilder. 297 people died, 20 of whom were children. The normal fault system is elongated NW–SE and composed of adjacent, west‐dipping, and echelon fault segments [Amato et al., 1998; Boncio et al., 2004; Chiaraluce et al., 2004]. ++..++>===>@@@@@@@@@@ "",,&)###)&//,,//;;9;;@@@@@@@@@@�� (�" �� ?��? This region of central Apennines has one of the highest seismic hazard in Italy [Akinci et al., 2009, and references therein]. Learn more. The hypocenter computed with the first P‐wave readings is relative to the emergent onset that appears as a small prelude of the main dislocation. The 2009 aftershock data allow us to define the fault geometries and hence to infer the relationship with adjacent fault segments ruptured during past events (the 1915 Fucino earthquake to the south and the 1703 Upper Aterno to the north, see Figure 2c). Several thousand foreshocks and aftershocks, starting from December 2008. L'Aquila lies about 50 km (31 miles) from Amatrice, the town at the center of last week’s earthquake in central Italy. While the northern portion is almost continuously releasing seismicity, the central part, i.e., the Abruzzi region, was silent during the past decades, with only few and sparse events occurring around the main faults [Bagh et al., 2007; De Luca et al., 2009]. The aftershock data suggest a size of ∼10 × 6 km2 for the main ruptured patch, whereas the second shallower patch is smaller, ∼5 × 5 km2. Geophysics, Biological April 2009). The dashed lines are the traces of vertical sections shown in Figure 2, and the solid lines are the mapped Quaternary faults [, Map of the 3200 relocated events (see the, By continuing to browse this site, you agree to its use of cookies as described in our, Journal of Advances [10] The second large event is the MW 5.6 April 7 (17:47) shock that occurred a few kilometers to the south of the main event, at a depth of 15 km (Table S1 of the auxiliary material), well constrained by the use of P‐ and S‐wave arrivals at 8 close temporary stations installed after the main event. In the first three days after the main event, we note a migration of seismicity from the main structure northward (Figure 1b), culminated with a Mw5.4 aftershock on April 9th. Table S1. The hypocenter is at about 11 km depth and its aftershocks define a steep SW‐dipping plane (sez‐1 in Figure 2b). 0 comments. See Plugins for a list of applications and supported file formats. Then, the ML ≥ 2.3 aftershocks have been carefully reanalyzed yielding high quality picks from digital recordings at three‐component seismic stations. Auxiliary material for this article contains two tables and two figures. The main shock fault segment extends for 15–18 km and dips at 45° to the SW, between 10 and 2 km depth. If you do not receive an email within 10 minutes, your email address may not be registered, The majority of the damage occurred in the medieval city of L'Aquila and in its province. Large earthquakes originate mainly on a narrow belt along the central Apennines (Figure 1a), accommodating a NE‐trending extension, with a rate of about 3 mm/yr [D'Agostino et al., 2008], progressively thinning the Apennines thrust and fold belt. The extension in this region is accommodated by two sub‐parallel sets of faults, the eastern and western normal fault systems [see Boncio et al., 2004], which include several Quaternary normal faults with clear signature at the surface and paleoseismological evidence of Holocene surface faulting earthquakes [Pantosti et al., 1996; Galadini and Galli, 2000; Papanikolaou et al., 2005; Roberts and Michetti, 2004]. Related to Geologic Time, Mineralogy Oceanography, Interplanetary 2009 L'Aquila Earthquake. ���� Adobe d� �� � This region of central Apennines has one of the highest seismic hazard in Italy [Akinci et al., 2009, and references therein]. Geophysics, Marine We show in Figures 1b and 1c the magnitude distribution and the space‐time evolution of the 2009 sequence using all the earthquakes located by the INGV National Seismic Network (RSN) from March 30 to May 15 (about 3200 events, see the auxiliary material). The main shock rupture activated a NW–SE trending, ∼15–18 km long fault. Vom United States Geological Survey wurde die Stärke des Hauptbebens mit der Momenten-Magnitude MW = 6,3 angegeben, das Istituto Nazionale di Geofisica e Vulcanologia gibt eine Magnitude von ML = 5,8 auf der Richterskala an. Italy is an earthquake prone country. The last dramatic event was the MW 6.7, 1915 Avezzano earthquake [Amoruso et al., 1998], located about 30 km to the south–west, that caused about thirty thousand deaths. A divergent, or constructive plate boundary is when two plates spread apart from each other, usually creating a large crack down the centre where they separated. The 2009 L'Aquila earthquake occurred in the region of Abruzzo, in central Italy.The main shock occurred at 03:32 CEST (01:32 UTC) on 6 April 2009, and was rated 5.8 or 5.9 on the Richter magnitude scale and 6.3 on the moment magnitude scale; its epicentre was near L'Aquila, the capital of Abruzzo, which together with surrounding villages suffered most damage. [2] On April 6th 2009 (1:32 UTC, 3:32 local time), a Mw6.3 earthquake struck central Italy, devastating the L'Aquila town and surrounding villages of the Abruzzi region, causing 300 deaths and leaving sixty thousand homeless.

The recent earthquake sequence near L'Aquila can only have reduced this discrepancy by ∼3–4 × 10 18 Nm, leaving a significant seismic strain deficit and subsequent earthquake hazard in the region. [15] Most of the aftershocks occur on the main fault plane around three patches that, we hypothesize, accounted for the largest slip during the main shock (the main asperities, see Figure 3). The geometry of this fault, barely illuminated by aftershocks, is still uncertain since the shallower earthquakes located above the hypocenter occur on the fault plane of the MW6.3 event, with ∼5 km gap in between. Six Italian scientists and an ex-government official are sentenced to six years in prison over the deadly 2009 earthquake in L'Aquila. Physics, Comets and The main shock hypocenter is located at the base of the aftershocks and close to the northwestern border of the fault. Effects . [3] After the 2009 MW6.3 event, two additional earthquakes, MW 5.6 and MW 5.4, occurred at the edges of the main structure, raising concern that additional M > 6 shocks could develop on one of the adjacent seismogenic faults [Galli et al., 2002]. The hypothesized asperity location well agrees with the maximum slip areas defined by DinSAR models [Atzori et al., 2009].

[4] In this study we use data from permanent and temporary seismic networks to define the space‐time evolution of the seismicity, providing accurate earthquake locations and the geometry of faults that accommodate the extension in this portion of the Apennines. Four hours before the main event, a ML3.9 foreshock occurred (fortunately spurring part of the population to pass the night outside buildings). The aftershocks clearly define an 15–18 km long, NW‐trending and ∼45°SW‐dipping fault, located above 10 depth, with a seismicity cut‐off at 2 km depth (sez‐2 in Figure 2b). [13] The aftershock data clearly show the location and geometry of the fault ruptured by the L'Aquila earthquake (Figures 2 and 3) . The final locations have formal errors less than 1.0 kilometer. The 2009 L'Aquila earthquake occurred in the region of Abruzzo, in central Italy. and Paleomagnetism, History of All the largest magnitude events (ML ≥ 4.0) originate at about 11–8 km depth (excluding the 7th April event), and most of them around this volume that can be a compliant part of the fault plane, surrounded by the main asperities.  Cause of the L'Aquila Earthquake of 2009   Different Plate Boundaries  There are three different plate boundaries: divergent, convergent and transform. [18] We thank all the technician staff of the INGV that allowed the acquisition of seismological data, and all the people involved in the surveillance duty. The final dataset consists of 17497 P‐ and 10815 S‐wave arrivals from 712 earthquakes at 81 seismic stations located within 100 km from the epicentral area.
