Abstract
Penelitian ini bertujuan untuk memetakan struktur bawah permukaan di area manifestasi lumpur panas di Desa Karumenga dan menginvestigasi sebaran lumpur panas. Akuisisi data dengan jumlah lintasan 4 yang masing-masing panjang lintasannya yaitu 240 m untuk lintasan 1 dan lintasan 3, 160 m pada lintasan 2, dan 480 m pada lintasan 4. Data lapangan diukur menggunakan resistivity and IP meter MAE-X612-EM menggunakan metode geolistrik tahanan jenis konfigurasi dipol-dipol. Data pengukuran kemudian diolah menggunakan Software Res2dinv . Hasil berupa model tampang lintang 2D bawah permukaan, lumpur panas diidentifikasi dengan nilai tahanan jenis 13,9 Ωm sampai 80 Ωm. Pada lintasan 1 lumpur panas terdapat di sepanjang lintasan dengan kedalaman bervariasi antara 0 sampai 32,5 m.

这项研究的目的是绘制Karumenga村滚烫泥浆出现地区的地下结构,并进行调查。4号轨道长度为240米(240英尺),3圈160米(160米),2圈160米(300英尺),4圈480米(300英尺)。现场数据使用区域性电阻和IP米jee - x612 - em使用极光配置类型的位置位置测量。然后使用re2dinv软件进行测量数据。结果是纬度2D表面之下,泥浆热表情识别模型和价值类型的囚犯13,9Ω80Ωm。在1号轨道上,热泥沿着这条轨道生长,深度从0到32.5米(200到32.5英尺)不等。2热泥浆沿着这条轨道运行,深度在0到24.5米之间。热泥3号轨道沿着这条轨道运行,深度从0到33.5米不等。在4号轨道上,热泥浆沿着这条轨道散布,深度为32米(200英尺)。根据分析热泥的结果,通过11冲浪软件获得了研究区域不匹配的信息。这项研究是对热泥地区的泥图集结构的研究。数据与数字行4的步调一致,第一行和第3行240米,第2行160米,第4行480米,第4行480米。数据场采用了电阻和IP米乘e- x612《测量。数据正在处理re2dinv软件。The results 2D are in The form of subsurface models,热泥浆和resistivity identified 13 . 9到公元80Ω的价值观。第一行,热泥沿着直线上升,从0到32.5米。第2行,热泥在这条线上出现,从0米到24米。第3行,热泥沿着这条线移动,从0米到33.5米。4排,一起跟着热泥是利差线a≤32米的深度。根据热泥分布的分析,它通过使用11种软件的Surfer,在研究区域的外外化水平上发布了信息。
