Explanation:

To evaluate the statements about volcanoes:

1. The strength is measured of a volcano by the Volcanic Explosive Index. - This statement is correct. The Volcanic Explosivity Index (VEI) is a scale used to measure the explosiveness of volcanic eruptions.

2. Iceland and the Philippines were created by volcanic activity. - This statement is also correct. Both Iceland and the Philippines are located along tectonic plate boundaries and have been formed by significant volcanic activity.

3. Volcanic soils are rich, deep and fertile and allow intensive agriculture to take place. - This statement is correct as well. Volcanic soils, known for their nutrient-rich characteristics due to the minerals they release upon weathering, are often very fertile and suitable for agriculture.

Since all three statements are correct, the correct answer is:

Option 4: 1, 2, and 3.
