Gunung Patuha terletak di Jawa Barat dan
memiliki kondisi tektonik yang dipengaruhi oleh aktivitas
subduksi di bagian selatan Pulau Jawa. Aktivitas vulkanik
yang menghasilkan berbagai jenis batuan, termasuk tuf,
lapili, breksi vulkanik, skoria, dan aglomerat. Penelitian
ini bertujuan untuk mengidentifikasi karakteristik erupsi
Gunung Patuha berdasarkan analisis stratigrafi batuan
di Kawah Putih. Metode yang digunakan adalah metode
deskriptif kualitatif, dengan data primer diperoleh melalui
observasi lapangan dan wawancara, serta data sekunder dari
studi literatur. Hasil penelitian menunjukkan bahwa kawasan
ini mencerminkan dinamika vulkanisme yang kompleks,
dengan berbagai fase erupsi, dari eksplosif hingga efusif.
Batuan tuf dan lapili mengindikasikan erupsi eksplosif
yang berulang, sementara keberadaan skoria dan aglomerat
mencerminkan aktivitas efusif dengan pelepasan gas yang
signifikan. Namun, erupsi Gunung Patuha belum mencapai
intensitas erupsi Plinian, sebagaimana ditunjukkan oleh
tidak adanya deposit pumis yang signifikan dan distribusi
material yang cenderung lokal. Penelitian ini diharapkan
dapat memberikan pemahaman mendalam tentang proses
vulkanisme Gunung Patuha. Temuan ini juga diharapkan
dapat berkontribusi pada upaya mitigasi bencana vulkanik
di kawasan tersebut.
Kata kunci: Gunung Patuha, stratigrafi, vulkanisme, erupsi.
Abstract
Mount Patuha is located in West Java and has
tectonic conditions influenced by subduction activity in the
southern part of Java Island. Volcanic activity produced a
variety of rock types, including tuff, lapilli, volcanic breccia,
scoria, and agglomerate. This research aims to identify the
eruption characteristics of Mount Patuha based on the
analysis of rock stratigraphy in Kawah Putih. The method
used is a descriptive qualitative method, with primary data
obtained through field observations and interviews, and
secondary data from literature studies. The results showed
that the area reflects complex volcanism dynamics, with
various eruption phases, from explosive to effusive. Tuff and
lapilli rocks indicate repeated explosive eruptions, while
the presence of scoria and agglomerate reflects effusive
activity with significant gas release. However, the eruption
of Mount Patuha has not reached the intensity of a Plinian
eruption, as indicated by the absence of significant pumice
deposits and the localized distribution of materials. This
research is expected to provide an in-depth understanding
of the volcanism process of Mount Patuha. The findings are
also expected to contribute to volcanic disaster mitigation
efforts in the region.
Keywords: Mount Patuha, stratigraphy, volcanism,
