			<content:encoded><![CDATA[<p>Pada tanggal 16 Juni 2010, telah terjadi serangkaian gempa Bumi di wilaya peairan Biak-Papua. BMKG melaporkan rangkaian gempa ini di awali oleh sebuah gempa berkekuatan 6.2 SR pada pukul 10:06:01 WIB dan terus berlanjut hingga saat ini (17 Juni 2010). Gempa dengan kekuatan terbesar yang dilaporkan oleh BMKG tercatat memiliki magnitude 7.1 SR dan terjadi pada pukul 10:16:28 WIB dengan kedalaman 10 km, hanya berselang beberapa menit dari gempa pertama. Sementara USGS melansir gempa terbesar dari rangkaian kejadian ini berkekuatan 7.0 Mw dengan kedalaman pusat gempa 28.8 km</p>

<p>Berdasarkan data terakhir yang diperoleh <em>Antara</em> Jayapura hingga Kamis (17/6/2010), gempa tersebut mengakibatkan dua orang meninggal, yaitu Rian (5) dan Damaria (45), serta dua orang luka berat, Rosalina (65) dan Barangkea (58). Kepala Bidang Data dan Informasi Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) Wilayah V Jayapura Sudaryono sebelumnya mengatakan, sedikitnya terdapat delapan kali gempa susulan dan kebakaran di enam lokasi berbeda di Serui. Beliau juga mengatakan bahwa kebakaran di enam lokasi itu termasuk kantor PLN Serui, sebuah rumah roboh di kawasan kelapa dua Kampung Warari, dan kantor RRI retak. Selain itu, masih banyak perumahan warga lainnya yang juga retak (kompas.com, 2010). Antara juga melansir sembilan kampung di wilayah distrik Yapen Selatan, Kabupaten Yapen Kepulauan, Papua, rusak parah akibat guncangan gempa bumi tektonik 7,1 skala richter Rabu kemarin (16/60 pukul 12:16 WIT).</p>
<p>gempa dengan mekanisme semacam ini (subduksi)  pernah menyebabkan tsunami di biak pada 1996.</p>

<p>why this earthquake make me so intereted?</p>
<p>I estimated so many insurance companies must paid big claims for this earthquake. My friends who go there looked so bad building construction in padang (the biggest city there).<br />
I wont give them a comment,..</p>
<p>I saw the indonesian geologist mailinglist and then Danny hilman N pronouncement in <a href="http://www.surya.co.id/2009/10/02/waspadai-gempa-mentawai-padang-baru-pemicu.html">http://www.surya.co.id/2009/10/02/waspadai-gempa-mentawai-padang-baru-pemicu.html</a>. he interpreted that fault in the deep of the subducted crust under sumatera island moved and generated that earthquake.</p>
<p>I saw the USGS body wave moment tensor solutions</p>
<div class="wp-caption alignnone" style="width: 409px"><a href="http://neic.usgs.gov/"><img title="body wave moment tensor" src="http://neic.usgs.gov/neis/eq_depot/2009/eq_090930_mebz/neic_mebz_fmt.gif" alt="mekanisme fokus" width="399" height="306" /></a><p class="wp-caption-text">focal mechanism</p></div>
<p><img src="/DOCUME%7E1/haikal/LOCALS%7E1/Temp/moz-screenshot.jpg" alt="" /></p>
<p>that is not the common form of focal mechanism of sumatera subduction, se the historic moment tensor bellow</p>
<p><a href="http://neic.usgs.gov/neis/eq_depot/2009/eq_090930_mebz/neic_mebz_m.jpg"><img class="alignnone" src="http://neic.usgs.gov/neis/eq_depot/2009/eq_090930_mebz/neic_mebz_m.jpg" alt="" width="317" height="285" /></a></p>
<p>it is quite different, so there are posibilities that there is one more seismic source that could generated big earthquake and hit the sumatera island besides Great sumatera faults system, mentawai fault, major tectonic subduction force, and fault/faults in indo-australia slab under the island</p>

			<content:encoded><![CDATA[<p>tulisan ini sengaja saya tulis dalam bahasa indonesia dikarenakan memang saya tujukan untuk wartawan-wartawan atau penulis-penulis serta editor yang mengurusi urusan gempa dari indonesia saja, belum punya waktu kiranya saya mengamati penulis-penulis lain.</p>
<p>berikut adalah cuplikan berita dari beberapa media yang cukup populer di Indonesia :</p>
<p><em>Sebanyak 5 orang tewas dan 13 lainnya menderita luka-luka akibat gempa <strong>7.1 SR</strong> yang menggoyang Honduras. Puluhan rumah penduduk dan bangunan publik juga dilaporkan rusak. (</em><a href="http://www.detiknews.com/read/2009/05/29/024448/1139029/10/5-korban-tewas-puluhan-bangunan-ambruk-" target="_blank">www.detiknews.com</a>)<br />
<em>Gempa berkekuatan <strong>7,1 skala richter</strong> yang mengguncang Honduras, Amerika Tengah, Kamis 28 Mei, menewaskan sedikitnya lima orang. Gempa merusak bangunan di bagian utara Hodnuras hingga kawasan yang berdekatan dengan Guatemala. (</em><a href="http://international.okezone.com/index.php/ReadStory/2009/05/29/18/224118/gempa-honduras-tewaskan-lima-orang">international.okezone.com</a>)</p>
<p>point saya pada 7.1 skala richter, coba perhatikan data dari USGS berikut.</p>
<p><a rel="#someid1" href="http://earthquake.usgs.gov/eqcenter/glossary.php#magnitude">Magnitude</a> <strong>7.1</strong></p>
<p><a rel="#someid9" href="http://earthquake.usgs.gov/eqcenter/glossary.php#parameters">Parameters</a> NST=300, Nph=300, Dmin=317.2 km, Rmss=1.15 sec, Gp= 36°,<br />
<strong>M-type=teleseismic moment magnitude (Mw)</strong>, Version=9</p>
<p>saya bold bagian parameter.</p>
<p>nah Mw dan Skala Richter (SR) adalah ukuran magnitude yang berbeda dan ditentukan dengan metode yang berbeda pula baca wikipedia aja biar lebih terang.</p>
<p>ini ada sedikit tabel yang menunjukkan perbedaannya :</p>

<p>di ambil dari <a href="http://en.wikipedia.org/wiki/Moment_magnitude_scale">sini</a></p>
<p>baca juga artikel <a href="http://en.wikipedia.org/wiki/Seismic_scale">ini</a> untuk penjelasannya.</p>
<p>Apakah penulis berita itu mengutip sesuatu entah dari mana dengan sok tau, atau apakah memang 7.1 skala richter itu magnitude nya???</p>
<p>pointnya, mereka yang hidup dari menyajikan berita untuk orang lain bertanggung jawab atas apa yang disampaikan, tentu berbeda denngan saya yang tidak berharap tulisan saya disini menghasilkan apa-apa dan tidak memberikan jaminan bahwa yang saya tulis disini adalah sesuatu yang ilmiah, jadi saya bisa suka-suka menulisnya, sesuatu yang anda sebagai ilmuwan, wartawan, penulis media informasi tidak bisa lakukan. Cheers :p</p>

<p>I am not really understand about honduras sourcezones, but from the images on the left (source from <a title="USGS website" href="http://earthquake.usgs.gov/eqcenter/recenteqsww/Quakes/us2009heak.php#summary" target="_self">USGS</a>) we could understand the usgs&#8217;s summary that said the shock occurred as the result of left-lateral strike-slip faulting on the Swan Islands Transform Fault (the yellow lines are the sources visualisation). and the orange star is epicentre of the earthquake.</p>
<p>left-lateral strike-slip faulting is mechanisme of fault deformation, imagine we stand on a side in front of fault line another side across the faul tline move to the left.</p>

<p>usgs&#8217;s momen tensor solution above show us that really strike-slip :p P imaging  pressure and T as dilatation area.</p>
<p>strike-slip machanisme will not caused tsunami, because just make a small vertical displacement. we need enough vertical displacement to generate a tsunami.</p>
<p>poor english, ah&#8230; i am still learning huh, so sorry hehehehe</p>
