Jakarta Badan Nasional Penanggulangan Bencana (BNPB) terus mendata kerusakan akibat gempa berkekuatan 6,1 Skala Richter (SR) di Sukabumi. Data sementara, ada 444 rumah rusak dan dua orang terluka.

"Hingga saat ini pukul 18.00 WIB dampak gempa 6,1 SR di barat daya Sukabumi, tercatat 2 orang luka ringan dan 444 rumah rusak," kata Kepala Humas BNPB, Sutopo Purwo Nugroho, lewat pesan tertulis, Rabu (6/6/2012).

Menurut Sutopo, kerusakan rumah tersebar di 20 desa dari 12 kecamatan di Kabupaten Sukabumi. Dari 444 rumah, 19 diantaranya rusak berat, 153 rusak sedang, dan 272 rusak ringan.

"Kerusakan rumah terbanyak terdapat di Kec Cilodog yaitu 269 rusak, yaitu 14 rusak berat, 120 rusak sedang, dan 135 rusak ringan. Kerusakan di Kecamatan Cilodog tersebut tersebar di 5 desa yaitu desa Cikarang, Cilodog, Tegalega, Cipamingkis, dan Mekar Jaya," jelas Sutopo.

Seperti diketahui gempa berkekuatan 6.1 Skala Richter mengguncang Sukabumi, Jawa Barat, pada Senin (4/6) pukul 18.18 WIB. Pusat gempa berada di kedalaman 24 kilometer dan berjarak 121 Km dari Sukabumi.

Keterangan dari Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) lokasi pasti gempa ada di titik 7.99 LS-106.19 BT. Tidak ada potensi tsunami akibat gempa ini. Gempa yang cukup besar ini terasa hingga ke beberapa daerah. Informasi yang dikumpulkan detikcom beberapa daerah yang merasakan goyangan akibat gempa adalah Sukabumi, Jakarta, Bogor, dan Bandung.

TRC BNPB dan BPBD Sukabumi masih di daerah untuk melakukan pendataan bencana.

Tokyo Jepang digoyang dua kali gempa dalam rentang 8 menit, Minggu (20/5/2012). Satu di antara gempa berkekuatan 6,2 SR namun tidak ada laporan kerusakan dan peringatan tsunami.

Gempa 6,2 SR terjadi pukul 16.20 waktu setempat, diikuti gempa susulan pada skala 5,7 SR pada pukul 16.28. Demikian diberitakan AFP.

USGS memperkirakan kekuatan gempa pertama pada skala 6. Kedalaman pusat gempa 10 km.

"Ketinggian laut mungkin berubah sedikit terkait gempa (pertama) namun tidak perlu dikhawatirkan kerusakan akibat itu," tulisnya.

Gempa dahsyat di Jepang terjadi pada 11 Mei 2011 dengan kekuatan 9,0 SR, yang memicu tsunami besar. Sebanyak 19 ribu orang tewas atau hilang.

Tectonic Summary

Seismotectonics of the Mediterranean Region and Vicinity

The Mediterranean region is seismically active due to the northward convergence (4-10 mm/yr) of the African plate with respect to the Eurasian plate along a complex plate boundary. This convergence began approximately 50 Ma and was associated with the closure of the Tethys Sea. The modern day remnant of the Tethys Sea is the Mediterranean Sea. The highest rates of seismicity in the Mediterranean region are found along the Hellenic subduction zone of southern Greece, along the North Anatolian Fault Zone of western Turkey and the Calabrian subduction zone of southern Italy. Local high rates of convergence at the Hellenic subduction zone (35mm/yr) are associated with back-arc spreading throughout Greece and western Turkey above the subducting Mediterranean oceanic crust. Crustal normal faulting throughout this region is a manifestation of extensional tectonics associated with the back-arc spreading. The region of the Marmara Sea is a transition zone between this extensional regime, to the west, and the strike-slip regime of the North Anatolian Fault Zone, to the east. The North Anatolian Fault accommodates much of the right-lateral horizontal motion (23-24 mm/yr) between the Anatolian micro-plate and Eurasian plate as the Anatolian micro-plate is being pushed westward to further accommodate closure of the Mediterranean basin caused by the collision of the African and Arabian plates in southeastern Turkey. Subduction of the Mediterranean Sea floor beneath the Tyrrhenian Sea at the Calabrian subduction zone causes a significant zone of seismicity around Sicily and southern Italy. Active volcanoes are located above intermediate depth earthquakes in the Cyclades of the Aegean Sea and in southern Italy.
In the Mediterranean region there is a written record, several centuries long, documenting pre-instrumental seismicity (pre-20th century). Earthquakes have historically caused widespread damage across central and southern Greece, Cyprus, Sicily, Crete, the Nile Delta, Northern Libya, the Atlas Mountains of North Africa and the Iberian Peninsula. The 1903 M8.2 Kythera earthquake and the 1926 M7.8 Rhodes earthquakes are the largest instrumentally recorded Mediterranean earthquakes, both of which are associated with subduction zone tectonics. Between 1939 and 1999 a series of devastating M7+ strike-slip earthquakes propagated westward along the North Anatolian Fault Zone, beginning with the 1939 M7.8 Erzincan earthquake on the eastern end of the North Anatolian Fault system. The 1999 M7.6 Izmit earthquake, located on the westward end of the fault, struck one of Turkey's most densely populated and industrialized urban areas killing, more than 17,000 people. Although seismicity rates are comparatively low along the northern margin of the African continent, large destructive earthquakes have been recorded and reported from Morocco in the western Mediterranean, to the Dead Sea in the eastern Mediterranean. The 1980 M7.3 El Asnam earthquake was one of Africa's largest and most destructive earthquakes within the 20th century.
Large earthquakes throughout the Mediterranean region have also been known to produce significant and damaging tsunamis. One of the more prominent historical earthquakes within the region is the Lisbon earthquake of November 1, 1755, whose magnitude has been estimated from non-instrumental data to be about 8.0. The 1755 Lisbon earthquake is thought to have occurred within or near the Azores-Gibraltar transform fault, which defines the boundary between the African and Eurasian plates off the west coast of Morocco and Portugal. The earthquake is notable for both a large death toll of approximately 60,000 people and for generating a tsunami that swept up the Portuguese coast inundating coastal villages and Lisbon. An earthquake of approximately M8.0 near Sicily in 1693 generated a large tsunami wave that destroyed numerous towns along Sicily's east coast. The M7.2 December 28, 1908 Messina earthquake is the deadliest documented European earthquake. The combination of severe ground shaking and a local tsunami caused an estimated 60,000 to 120,000 fatalities.

Italia diguncang gempa, tiga orang tewas


Italia diguncang gempa, tiga orang tewas

Terbaru  20 Mei 2012 - 14:25 WIB
Gempa Italia
Balaikota Sant Agostino rusak parah akibat gempa yang mengguncang Italia Utara.
Sebuah gempa berkekuatan 6,0 dalam skala Richter mengguncang kawasan sebelah utara kota Bologna, Italia, Minggu (20/5) dan mengakibatkan sedikitnya tiga orang meninggal dunia.
Gempa itu terjadi di kedalaman 10km dan terjadi pada pukul 4.00 dini hari atau sekitar pukul 9.00 waktu Indonesia.
Selain itu gempa yang cukup kencang tersebut membuat ribuan orang berhamburan keluar rumah untuk menyelamatkan diri.
Aparat pemerintah setempat mengatakan ketiga korban tewas terjadi saat bangunan tempat mereka bekerja runtuh.
Sejumlah televisi Italia menayangkan kerusakan berbagai bangunan termasuk pabrik dan gereja. Sementara itu, sejumlah gempa susulan dilaporkan telah terjadi.
Televisi juga menayangkan warga tengah membersihkan puing-puing rumah, kantor dan bangunan-bangunan kuno, termasuk bagian dari benteng kuno di salah satu kota.
Tim penyelamat saat ini menyisir kawasan bencana karena muncul kabar sejumlah orang terjebak di bawah reruntuhan bangunan.
Wartawan BBC di Roma Alan Johnston melaporkan Italia Utara kerap diguncang gempa kecil namun negeri itu sudah terbiasa menghadapi bencana ini.
Gempa besar terakhir di Italia terjadi di kota L'Aquilla pada 2009 yang menewaskan hampir 300 orang.
