In geology and volcanology, tectonic lake is known as maar. Maar was created for volcanic explosion with round shape and steep wall. Maar was formed by freatic and freato magmatic explosion. In 1907, until today there are 10 maar on earth. But in the prehistoric period, there were many maar created. The biggest and most amazing maar was created at Pematang Bata, in 1933. 2 maar with 1 km and 2 km diameter. Maar is a very rare phenomenon.

Volcano Explosion Level

LEVEL 0 (Hawaiian Level)
Hawaiian explosion is type of volcano explosion which lava from source is relatively in shallow explosion, low level and called so as the characteristic resembles Hawaiian volcano.Usually it is an effusive explosion, magma basaltic with low viscosity, in low gas contents and high temperature on hole. With eject-volume less than 10.000 m3 and plume less than 100 meters. Volcano in this category: Mt Kilauea Explosion in Pacific and Mt Piton de la Fournaise.

LEVEL 1 (Strombolian Level)
This type of explosion is relatively low level explosion, and named after volcano in Italy and the explosion constitutes of ejecting lava, lapili and lava bomb to hundred meters high. They have medium and small volume and sporadic sound. Volume of ejects more than 10.000 m3 and plume 100 – 1000 m. Explosion in this category: Stromboli Volcano in Italya explosion in April 2009 and Mount Nyiragongo explosion in Congo in 1977 dan 2002.

LEVEL 2 (Volcanian Level)
This term was used initially by Giuseppe Mercalli, when he overlooked explosion at Volcano Island in 1880-1890. The description about the explosion type is used around the world, marked by thick ash cloud with gas the explodes from crater and rises to the sky above its summit. Eject volume more than 1.000.000 m3 and plume 1-5 km. Explosions in this category: Mt Galeran (Columbia) explosion on August 25th 2010 and the worst in 1993. Mt Sinabung in Indonesia last eruption in September 2010.

LEVEL 3.(Pelean Level)
Pelean explosion has condensed magma, rhyolitic or andesit, they are involved and similar to volcanian. Most important in a Pelean explosion is erosion of hot volcanic ash, pyroclastic stream and forming a lava dome. Short-circuit of ash or forming of pumice cone can also be seen. Volume eject more than 10.000.000 m3 and plume 3-15 km. Explosion in this category: Mount Nevado del Ruiz explosion in Kolombia. And Mount Soufrière Hills at Monsteratt ,Karibia.

LEVEL 4
This level is similar to Level 3 and Level 5 and ejects volume more than 0.1 km3 and plume 10-25 km. Explosion in this category: Mt Pelée in Martinique and huge eruption was in 1902. Mt Eyjafjallajökull in Iceland, last eruption was in May 2010.

LEVEL 5 (PLINIAN EXPLOSION)
Plinian explosion is also known as Vesuvian exxplosion, and volcano explosion is marked with similarity to Mt Vesuvius date back 79 (as written by young Plinius that killed his uncle Pliny the Elder). Palinian explosion characteristic is gas column and volcanic ash soars high to stratosphere, the highest atmosphere layer. The main characteristic is expelling pumice and very strong continues gas explosion. Volume ejecta more than 1 km3 and plume 20-35 km. Explosion in this category is Mt Vesuvius explosion in Italy in 1944 and huge eruption in 79 BC. Mt St Helens eruption in USA in 1980 that killed 81 people.

LEVEL 6
This level is similar to Level 5 and Level 7. Volume eject more than 10 km3 and plume more than 30 km. Volcano in this category is in 1883 that yielded tsunami. Mt Pinatubo in the Phillipines that killed 847 in 1991.

LEVEL 7 (Ultra Plinian Level)
According to Volcanic Explosivity Index Smithsonian Institution, VEI 6 to 7 are classified as Ultra Plinian. They are defined by ash of more than 25 or 16 miles high and volume of explosion 10 km3 from 1000 km3. Example in this category are Mt Tambora (Indonesia) explosion in 1815. The mountain was gone after the explosion.

LEVEL 8 ( Super Volcanic Level)
From its name one can imagine how huge this explosion. Explosions in this category are: supervolcano Yellowstone, Creek lava that exploded 640.000 years ago, and expelled 240 km cubic (1.000 km3) of stone and ash to the sky and this volcano is still active. Toba explosion around 67.500 to 75.500 years ago. Toba explosion was the last of seris of 3 explosions that created caldera from volcano, the previous caldera was created 7000.000 and 840.000 years ago. The last explosion had explosivity index of volcanic 8 or called as mega-colosal and could be the biggest volcano explosion in the last 25 million years. And quake in 2004 that struck Sumatera and changed earth shape as detected by GRACE satellite. The quake activity can initiate magmatic activity of Toba.
